puce Description of Chaetomium aureum, Corynascus sepedonium and Coniochaeta hansenii newly recorded from Italy, and a key to coprophilous Chaetomiaceae and Coniochaetaceae PDF
  Doveri F. 7-24
Abstract: The ongoing survey of coprophilous basidiomycetes and ascomycetes from Italy results at this stage in describing further Chaetomiaceae and Coniochaetaceae species isolated from herbivore dung. The high frequency of occurrence on this substrate is explained with their supposed cellulolytic ability and with the abundance of cellulose and lignin in specific types of dung. Chaetomium aureum, Corynascus sepedonium and Coniochaeta hansenii are extensively discussed. A worldwide key to Coniochaeta with poly-spored asci is provided. A key to coprophilous Chaetomiaceae and Coniochaetaceae from Italy is also provided and each species is pictured by one or more coloured photographs.
puce Annulohypoxylon michelianumuna rara especie laurícola recolectada en el noroeste español PDF
  Rubio E., De la Peña S. 25-29
Abstract: The authors describe two Spanish (NW) collections of the uncommon xylariaceous and lauricolous fungus Annulohypoxylon michelianum.
puce Protocreopsis caricicola (Hypocreales, Bionectriaceae), the first species of Protocreopsis reported from a temperate area of the northern hemisphere PDF
  Lechat C., Fournier J., Richter T. 30-32
Abstract: Protocreopsis caricicola sp. nov. is described and illustrated based on a collection on Carex acutiformis in Germany. The placement of P. caricicola in Protocreopsis is supported by morphological characters of both sexual and asexual morphs and analysis of LSU sequences. This species has smooth ascospores as does Protocreopsis korfii Lechat & J. Fourn. but differs from it in having significantly smaller ascospores and a different ecology.
puce Some Annulohypoxylon spp. (Xylariaceae) from French Guiana, including three new species PDF
  Fournier J., Lechat C. 33-53
Abstract: This survey deals with Annulohypoxylon spp. collected in two French Guiana locations during two weeks in June 2012. Two species, A. leptascum var. macrosporum and A. stygium, previously reported, were collected. In addition, we collected A. moriforme s.l., A. purpureopigmentum (first collected in Brazil), and three new species, A. fulvum, A. nouraguense and A. subnitens. All species are described and illustrated; a dichotomous key is provided. In conclusion, some problems in description of morphological features of Annulohypoxylon, especially the ostiolar discs, are discussed.

Fascicule 2 - Mars 2016 (en ligne 15/03/2016)

puce Hydropisphaera znieffensis, a new species from Martinique PDF
  Lechat C., Fournier J. 55-58
Abstract: A detailed description of Hydropisphaera znieffensis sp. nov. is presented, based on a collection on dead leaf of Cyathea arborea (L.) Sm. in Martinique (French West Indies). The asexual morph has been obtained in culture and sequenced. This species has coarsely verrucose ascospores, an unusual feature in the genus Hydropisphaera.
puce Lasionectriella, a new genus in the Bionectriaceae, with two new species from France and Spain, L. herbicola and L. rubioi PDF
  Lechat C., Fournier J. 59-65
Abstract: Lasionectriella rubioi gen. and sp. nov. and L. herbicola sp. nov. are described and illustrated based on collections from France and Spain. The asexual morph of L. rubioi was obtained in culture and cultures of both species were sequenced. The genus is placed in the Bionectriaceae based on ascomata not changing colour in 3% KOH or lactic acid, acremonium-like asexual morph and phylogenetic comparison of LSU sequences with species in 13 genera of the Bionectriaceae. Lasionectriella is primarily characterized by subglobose, pale yellow, pale orange to dark brownish orange, non-stromatic ascomata with a conical apex and ascomatal surface covered by thick-walled hyphae proliferating from base and agglutinating to form a fringe around the upper margin of ascomata. It is morphologically and phylogenetically compared with the most similar genera Ijuhya, Lasionectria and Ochronectria.
puce Freshwater Ascomycetes: Submersisphaeria aquatica (Annulatascaceae), reported for the first time from France (Morvan) and from Europe PDF
  Fournier J., Gardiennet A., Lechat C. 66-72
Abstract: A distinctive aquatic fungus belonging to the Sordariomycetes was recently collected twice on submerged wood in a peat bog and in a small brook in Morvan region (France). Based on its more or less immersed perithecial and ostiolate ascomata, cylindrical unitunicate asci with a massive inamyloid apical apparatus and brown, two-celled fusiform ascospores with small bipolar cap-like appendages, this fungus was identified as Submersisphaeria aquatica K.D. Hyde. This species, so far known only from Australia and USA, is reported from France and Europe for the first time. Herein, we provide a detailed morphological description of this fungus and compare it with material from the USA. The presence of minute germ pores beneath the bipolar appendages of the ascospores is assessed for the first time, in American and European material as well. Repeated attempts to grow the ascospores in culture on artificial media were unsuccessful.
puce Nuevas aportaciones al conocimiento de Xylaria crozonensis (Ascomycota, Xylariaceae) PDF
  Rubio E., Marcote J.M.C., Costa J.M. 73-76
Abstract: Xylaria crozonensis on twigs of Quercus robur and Fagus sylvatica is reported for the first time from Spain. A description and illustrations of both macroscopic and microscopic characters are provided.

  Roth J.-J., Van Vooren N. 77-82
Abstract: Gibellula pulchra is a parasitic fungus on Arachnids, rather common and widely distributed worldwide. This notice provides a full description based on several collections, accompanied by illustrations in colors and SEM photographs of the main microscopic characters. A brief history of hyphomycetes growing on spiders is proposed. The systematics of this species is discussed, especially through the article 59 of ICN (Melbourne).

Fascicule 3 - Mai 2016 (en ligne 05/05/2016)

puce Studies on Hypoxylon ferrugineum (Xylariaceae), a rarely reported species collected in the urban area of Graz (Austria) PDF
  Friebes G., Wendelin I. 83-90
Abstract: Hypoxylon ferrugineum has been collected repeatedly on branches of Tilia in the urban area of Graz. It is described and illustrated based on this newly collected material as well as the previously known collections from Austria. An overview of the known distribution of H. ferrugineum is given. Its ecology, host specificity, and some newly observed as well as previously rarely reported morphological characters are discussed. Hypoxylon ferrugineum appears to be a distinct and well-characterized species based on morphology as well as the results of phylogenetic analyses of β-Tubulin, α-Aktin, and ITS sequences.
puce Belonioscyphella hypnorum (Helotiales), a rarely reported bryoparasitic ascomycete new for the Czech Republic PDF
  Egertová Z., Hairaud M., Sochor M. 91-95
Abstract: Belonioscyphella hypnorum is published from the Czech Republic for the first time. It was found in three localities in Moravia — in all cases in calcareous areas at an altitude around 300 m asl., on wood, soil or a limestone boulder covered with its hosts. Didymodon rigidulus, Eurhynchium schleicheri, Homalia trichomanoides, Orthotrichum sp. and Radula complanata are newly recognized as host bryophytes of the species. Macroscopic and microscopic descriptions based on fresh material, photos of apothecia and microstructures and DNA sequence data from three nuclear genomic loci are provided. Five additional new localities of the species from Europe and Canada are listed.
puce Varicosporellopsis, a new aquatic genus from southern France PDF
  Lechat C., Fournier J. 96-100
Abstract: Varicosporellopsis aquatilis gen. and sp. nov. is described and illustrated based on two collections on submerged wood in southern France. An acremonium-like asexual morph was obtained in culture and sequenced. The genus is placed in the Nectriaceae based on its asexual morph and phylogenetic comparison of ITS and LSU sequences with 21 genera of Hypocreales including 14 genera in the Nectriaceae and 7 genera in the Bionectriaceae. Varicosporellopsis is primarily characterized by obpyriform, pale orange, non-stromatic ascomata not changing colour in 3% KOH, becoming very pale yellow to nearly hyaline in lactic acid, short-ribbed ascospores, freshwater habitat and an acremonium-like asexual morph.
puce Jafnea pallida (Pezizales), a new name for a cup fungus rediscovered in Tasmania PDF
  Gates G., Van Vooren N. 101-104
Abstract: A modern description is provided for Geopyxis pallidus, a species described by L. Rodway in 1920, from the here selected lectotype and additional recent collections from Tasmania. Based on its morphology, we recombine G. pallidus into the genus Jafnea. Recent records of Jafnea pallida comb. nov. from Tasmania have been misnamed as the morphologically similar Tarzetta jafneospora. The two species can be distinguished by their different spore ornamentation.
puce Genea cephalonicae sp. nov. (Ascomycota, Pezizales), a new hypogeous species from Greece PDF
  Kaounas V., Agnello C., Alvarado P. 105-110
Abstract: A new species of Genea Vittad. from Greek forests of Abies cephalonica is proposed based on morphological and genetic studies. Macroscopic images of fresh specimens, as well as observations made under optical microscopes, drawings, a 28S rDNA phylogenetic tree and a small key are provided.
puce Podospora bullata, a new homothallic ascomycete from kangaroo dung in Australia PDF
  Bell A., Mahoney D., Debuchy R. 111-118
Abstract: Podospora bullata sp. nov. is described and illustrated based on five kangaroo dung collections from Australia. The species is placed in the genus Podospora based on its teleomorph morphology and its ITS sequence from a fertile homothallic axenic culture. Perithecial necks are adorned with prominent simple unswollen filiform flexuous and non-agglutinated greyish hairs. Ascospores are characterized by minute pedicels, lack of caudae and an enveloping frothy gelatinous material with bubble-like structures both in the amorphous gel and attached to the ascospore dark cell. No anamorph was observed.

puce New records of two pyrophilous ascomycetes from Siberia: Pyropyxis rubra and Rhodotarzetta rosea PDF
  Filippova N., Bulyonkova T., Lindemann U. 119-126
Abstract: The paper reports the first findings of Pyropyxis rubra and Rhodotarzetta rosea from Asian Russia (West Siberia). The ecological conditions, i.e. vegetation, substrates and phenology of both species are described and compared with earlier publications. Also the morphological characteristics are described and depicted by photographic images and the differences between these quite similar species are highlighted. P. rubra has been cultivated in vitro. The paper provides descriptions of the anamorphic stage and culture growth on different media.
puce The genus Annulohypoxylon (Xylariaceae) in Guadeloupe and Martinique (French West Indies) PDF
  Fournier J., Lechat C., Courtecuisse R. 127-156
Abstract: This survey deals with the Annulohypoxylon spp. collected in the French West Indies in the course of an ongoing inventorial work on the mycobiota of these islands initiated in 2003. Based on the evaluation and comparison of their morphological characters, eleven species are described, illustrated and discussed, including three new species, A. caravellense, A. ramulorum and A. splendens and a taxonomically unsettled species provisionally referred to A. moriforme. Other recorded taxa include A. atroroseum, A. leptascum, A. moriforme var. microdiscum, A. nitens, A. purpureopigmentum, A. purpureonitens and A. stygium, of which only the latter was already known from Guadeloupe. A dichotomous identification key is provided.
puce Erioscyphella lunata (Lachnaceae), a rare discomycete collected in Spain PDF
  Tello S., Baral H.-O. 157-162
Abstract: The rare discomycete Erioscyphella lunata, inhabiting coniferous leaves and originally described from China, is re-described from a recent collection from southern Spain, which is the first report from Europe. Its molecular data are compared to the closest species and confirm its distinctness from the recently described smaller-spored E. curvispora.
puce Lamprospora verrucispora sp. nov. (Pezizales) PDF
  Vega M., Eckstein J., Van der Kolk H.-J. 163-171
Abstract: A description and illustrations of both macroscopic and microscopic characters of Lamprospora verrucispora sp. nov. are provided. Differences from other bryophilous Pezizales with globose ascospores ornamented with isolated warts are discussed and a dichotomous key to these species is given. Gall formation on rhizoids and chloronema of the bryophyte host Campylopus pyriformis is described and illustrated. This represents the first report of gall formation for a species of the genus Lamprospora.
puce Xanthonectria, a new genus for the nectrioid fungus Nectria pseudopeziza PDF
  Lechat C., Fournier J., Moreau P.-A. 172-178
Abstract: A new genus, Xanthonectria, is proposed for the enigmatic taxon Nectria pseudopeziza. Xanthonectria is characterized by nonstromatic, soft-textured, superficial, glabrous, pale yellow to bright orange nectria-like ascomata, not changing color in 3% KOH or lactic acid, long fusiform, multiseptate ascospores and an acremonium-like asexual morph. Its placement in the Bionectriaceae and its relationship to other members of this family are based on morphological, cultural and molecular data.

Fascicule 5 - Novembre 2016 (en ligne 3/11/2016)

puce Compte rendu de la session Ascomycota Zone alpine 2015 PDF
  Van Vooren N. 179-184

puce Chaetomium convolutum and C. hexagonosporum from Italy with a morphological revision of the group-bostrychodes PDF
  Doveri F. 185-198
Abstract: Chaetomium convolutum, newly isolated from herbivore dung in a survey of coprophilous ascomycetes and basidiomycetes, is first described from Italy and compared with other species of the so called “group-bostrychodes”. The taxonomic uncertainty, still present in this group despite a recent comparative, morphological and molecular study, led the author to revise all Italian collections of species related to C. convolutum, and to prove that also the very rare C. hexagonosporum is present in Italy. The morphological features of C. hexagonosporum are described in detail and particularly compared with those of C. convolutum. The results of this review confirm the existence of several intermediates in the group-bostrychodes, for which a much more extended revision is hoped.
puce Three Cercophora species from Indian elephant dung. An opportunity to establish new combinations and a new taxon PDF
  Doveri F. 199-220
Abstract: Elephant dung, when compared with other dungs from mammalian herbivores, was regarded as an ideal substrate for cellulolytic fungi. One sample of Indian elephant dung, examined for detecting coprophilous ascomycetes, was found to have developed three different Cercophora species. Cercophora elephantina, Cercophora sp. of the complex-sordarioides, and a new species, C. cephalothecoidea, were classified based on morphological characteristics. C. elephantina was described in detail and compared with species having the so called “pseudobombardioid” peridium. Cercophora sp. and C. cephalothecoidea were described, compared and placed in keys with species having a membraneous or carbonaceous peridium, respectively. Bombardia mutabilis and B. rostrata were recombined in Cercophora. Following recent phylogenetic analyses, the morphological and physiological features of family Lasiosphaeriaceae, Cercophora and related genera were re-examined and discussed.
puce Xylaria xylarioides (Xylariaceae), a subtropical species reported for the first time from Europe PDF
  Fournier J., Delgado M.A., Castillo J. 221-226
Abstract: Xylaria xylarioides is reported for the first time from Europe based on two recent collections from Catalonia and Galicia in Spain, and three previous unpublished records including one from Corfu (Greece) and two from Tenerife (Canary Islands) made by Dr. Walter Jaklitsch. An illustrated description of the material collected in Galicia is provided together with comments on the morphological variations encountered in X. xylarioides, its known distribution worldwide, ecology and taxonomic affinities.
puce Trichophaea dougoudii sp. nov. (Pezizales), un nouveau discomycète de l’étage alpin  Open Access PDF
  Van Vooren N. 227-234
Abstract: A Trichophaea species collected in Alpine zone in France, with characters close to those of T. woolhopeia, offers the opportunity to confirm — after a morphological and phylogenetic analysis — that the latter represents a complex of mycorrhizal species difficult to split morphologically. The morphological differences seen on this collection, in particular the size and shape of the ascospores, associated to its alpine ecology, and a probable relationship with Bistorta vivipara, are confirmed by molecular data. We propose it as a new species under the name T. dougoudii.
puce Sclerotinia cirsii-spinosissimi, a new species from the Alps PDF
  Senn-Irlet B., Peter M. 235-240
Abstract: Sclerotinia cirsii-spinosissimi is described as a new species from bracts of Cirsium spinosissimum based on morphological, cultural and molecular studies. Ascospore size and absence of small lipid bodies inside the spores are distinctive, medium sized sclerotia are typically produced on solid media in cultures. This description includes earlier molecular studies showing a close relationship to S. borealis. A key is added to Sclerotinia species from arctic-alpine habitats. - Volume 7

puce Pezizaceae taxonomy and classification: Boudier, Cooke and Korf PDF
  Pfister D. 239-244
Summary: Richard Korf is an important figure in the study of discomycetes. His contribution as teacher and scholar in relationship to Boudier’s masterwork, the Icones Mycologicae, is commented upon particularly in regard to the classifications used for the Pezizaceae. Although it has been common practice to recognize a single genus Peziza for most of the species in the Pezizaceae, molecular phylogenetic studies have shown that the genus Peziza is diverse and is not monophyletic. Boudier’s classification shows a more accurate picture of the diversity within the family than later classifications. Comments on the Icones and Cooke’s Mycographia are included as they relate to graduate training and opportunities offered by Richard Korf in his long career as a teacher.
puce The Richard P. Korf Herbarium and CUP’s geographical collections: the enduring legacy of a globe-trotting mycologist  Open Access PDF
  LaGreca S. 245-254
Summary: Richard P. Korf’s many contributions to herbarium CUP are spotlighted, with an overview of his personal herbarium, and the thousands of foreign specimens he has given to CUP’s geographical collections. Dick’s foreign fieldwork is summarized from 1957 to the present, giving a rough itinerary of Dick’s professional life. A table of fungal taxa described or recombined by Dr. Korf is provided.
puce Hymenoscyphus menthae, H. macroguttatus and H. scutula, a comparative taxonomic study emphasizing the value of spore guttulation and croziers PDF
  Baral H.O. 255-287
Summary: The taxonomic value of spore guttulation (lipid pattern inside of mature ascospores) studied with the light microscope from fresh but also dried collections is illustrated mainly for the two species of Hymenoscyphus extensively treated here. Also, the value of croziers at the ascus base is emphasized. The high intraspecific consistency of these characters permits rapid recognition of these species in the living state: H. menthae with multiguttulate ascospores and simple-septate asci, H. macroguttatus (= H. menthae s. auct.) with spores containing a few large oil drops and asci arising from croziers. Further valuable characteristics in the genus Hymenoscyphus concern the shape of ascospores (homo- versus heteropolar), the presence of polar setulae on them, and the vacuolar guttules in the living paraphyses. The neglect of spore guttulation due to the current dominance of herbarium studies, and also the neglect of croziers resulted in much confusion and name changes in this group of fungi. The traditional delimitation of taxa within Hymenoscyphus according to the substrate (lignicolous, herbicolous, pteridicolous) is questioned because quite a few species turned out to be highly plurivorous. The present type studies led to the following conclusions: (1) Hymenoscyphus menthae is an earlier synonym of H. consobrinus. (2) H. pteridicola Thind & Sharma is conspecific with H. menthae s. auct. and is replaced by the name H. macroguttatus because of the homonym H. pteridicola (Crouan) O. Kuntze. (3) Helotium repandum var. rumicis, H. julianum, and H. stramineum are later synonyms of Hymenoscyphus menthae. (4) Helotium geiphilum and Hymenoscyphus vitellinus are conspecific and hardly separable from the older H. scutula whilst Svrček’s interpretation of H. vitellinus mainly concerns H. menthae. (5) Helotium scutula var. solani might also be a synonym of Hymenoscyphus scutula, but type material could not be located. (6) The new species H. sharmae is described for collections from India (Himalaya) issued under the name Helotium scutula var. solani; it resembles H. trichosporus but differs in 4-spored asci. (7) A syntype of Helotium hyalopes in M contains a mixture of two similar species with scutuloid spores; possibly neither of them are synonymous with Hymenoscyphus vitigenus, a species described with homopolar spores and requiring restudy of the type. Molecular data supports a close relationship between H. menthae and H. repandus, both having a yellow disc and homopolar ascospores, but the data suggests a strong separation from the bulk of Hymenoscyphus s. str., which usually have heteropolar (scutuloid) but exceptionally also homopolar (H. macroguttatus) spores, and often whitish though also yellow apothecia.

puce The British species of Otidea (2) O. alutacea and related taxa PDF
  Parslow M., Spooner B. 295-302
Summary: The typification of Peziza alutacea Pers., the basionym of Otidea alutacea, is discussed, together with an analysis of British collections of O. alutacea and related taxa. Amongst British collections of O. alutacea sensu lato at least four closely related phylogenetic taxa are present. One of the latter is morphologically indistinguishable from that referred to O. alutacea sensu stricto by Olariaga et al. (2015), two others have smaller spores than those of the epitype designated by Carbone (2011), but are indistinguishable from each other except for subtle difference in hymenium colour. One taxon is morphologically distinct from the epitype in spore size range and in hymenium colour. An ITS sequence from a British collection is identical to those of clade 1 of Olariaga et al. (loc. cit.). This clade is strongly supported within the O. alutacea complex and warrants recognition at varietal level. It is described here as O. alutacea var. parvispora. In addition, the interpretations of O. felina and of O. alutacea var. microspora are considered, and an aberrant specimen with ovoid spores belonging to a fourth clade is reported. A lectotype is selected for O. alutacea var. microspora.
puce Lepidotia hispida: a spectacular member of the Pezizaceae PDF
  Van Vooren N., Van den Berg-Blok A., Verkley G. 303-306
Summary: A recent collection of Lepidotia hispida (syn. Peziza quelepidotia), a very rare species, characterized in particular by stipitate ascomata, has been studied in depth. Description of macro- and micro-characters, illustrations, and comments are provided. Pure cultures have been obtained and deposited in the CBS Collection, and sequences deposited in GenBank.
puce Protocreopsis korfii (Hypocreales, Bionectriaceae), a new species from Martinique (French West Indies) PDF
  Lechat C., Fournier J. 307-310
Summary: Protocreopsis korfii sp. nov. is described and illustrated based on a collection on Heliconia bihai in Martinique. The placement of P. korfii in Protocreopsis is supported by morphological characters and analysis of LSU sequences. This species has smooth ascospores 35–46 × 7–8.5(–9) µm, shorter than the most closely related species, P. fusigera.
puce “MolliBase”, a new sequence database including unidentified Mollisia and its allied genera PDF
  Hosoya T., Jinbo U., Tsujino N., Tanney J. 311-314
Summary: Mollisia and its allied genera are known to occur worldwide as saprophytes and are easily cultured, but difficult to identify. They are also known as root endophytes, but a lack of morphological characteristics of endophytic isolates makes their identification challenging. To facilitate connecting apothecial morphology with isolates based on sequence data, a new database called MolliBase was designed. The database provides photographs of apothecia, line drawings of apothecial elements, sequences obtained from the culture, and specimen and culture information. Initially, a dataset comprising 51 specimens from Japan is released.
puce Phylacia korfii sp. nov., a new species of Phylacia (Xylariaceae) from French Guiana, with notes on three other Phylacia spp. PDF
  Fournier J., Lechat C. 315-319
Summary: During a field trip to French Guiana in June 2012, a distinctive species of Phylacia was collected. It appeared to differ from all known species by significantly larger and pear-shaped ascospores and thus it is described as the new taxon P. korfii J. Fourn. & Lechat. We also noticed the presence of a germ slit on ascospores and we observed that fragments of the stromatal crust yielded pigments in 10% KOH, two characters so far rarely or not documented in this genus. Similar investigations carried out on three other Phylacia spp. showed that recording these characters is taxonomically relevant and should facilitate a better appraisal of the known species and the segregation of new taxa.
puce Rommelaarsia flavovirens gen. et sp. nov. (Helotiales), a new discomycete on Equisetum with a peculiar asexual state PDF
  Baral H.O., Haelewaters D. 321-330
Summary: Rommelaarsia flavovirens gen. et sp. nov. is proposed. This inoperculate discomycete is known only from two collections in Western Europe, fruiting in spring on dead stems of Equisetum arvensis. An affiliation with the family Hyaloscyphaceae is suggested by the presence of short hairs on the superficially growing apothecium. The species is associated with an unusual, likewise unknown asexual state with large multiguttulate, holoblastic phragmoconidia formed in sporodochia. Phylogenetic analyses of the internal transcribed spacer (ITS) and large subunit (LSU) ribosomal DNA show that Rommelaarsia has an uncertain position within the Helotiales. Our analyses consistently show a close relationship to Cistella and Psilachnum, but there is no support for this placement. Bayesian analysis moderately supports the Cistella + Psilachnum + Rommelaarsia clade, which hints at the placement of Rommelaarsia within Hyaloscyphaceae. This agrees with the morphological data.
puce Cookeina korfii, a new species hidden in Cookeina tricholoma PDF
  Iturriaga T., Xu F., Pfister D.H. 331-335
Summary: Cookeina korfii (Ascomycetes, Pezizales, Sarcoscyphaceae) is described from the Philippines. Ascospores are smooth, smaller than Cookeina tricholoma (Mont.) Kuntze, and hairs are more flexuous than in C. tricholoma. Analyses of the ITS region shows it to be close to Cookeina tricholoma and Cookeina sinensis Z. Wang.
puce Rutstroemia alnobetulae sp. nov. (Helotiales, Rutstroemiaceae), une espèce nouvelle des aulnes verts PDF
  Dougoud R. 336-340
Summary: Description and illustration of a new Rutstroemia species, R. alnobetulae, are provided, which is characterized by its spore dimensions, the amyloid reaction of paraphyses, and by its host, dead wood of Alnus alnobetula (syn. A. viridis).
puce Pseudotricharina intermedia (Pezizales), a new genus and a new species discovered in the Mediterranean area PDF
  Van Vooren N., Tello S., Vega M. 341-346
Summary: Three collections of a cup-fungus found in the Mediterranean basin in three different localities (southern Spain, southern Italy and Crete) are presented as a new genus and a new species of Pezizales. Its morphology is similar to that of Tricharina species, but some of its microscopic characters, i.e. ascospores structure, disagree with the usual concept of this genus. Morphological study and phylogenetic analysis have been conducted to determine the correct position within the Pyronemataceae.
puce Une espèce nouvelle du genre Peziza (Pezizales) : P. montirivicola spec. nov. PDF

Summary: Description and illustrations of a new species of Peziza, P. montirivicola, are given. It is characterized by its habitat and its occurrence on very wet substrates, stipitate apothecia, with a very granular receptacle, ascospores surrounded with a hyaline gel coating, and its paraphyses with yellow oil drops.
puce Fun with the discomycetes: revisiting collections of Korf’s anamorphic Pezizales and Thaxter’s New England truffles leads to a connection between forms and the description of two new truffle species: Pachyphlodes pfisteri and P. nemoralis PDF
  Healy R., Hobart C., Tocci G.E., Bóna L., Merényi Z., Paz Conde A., Smith M.E. 357-366
Summary: Pachyphlodes is a pleiomorphic pezizalean truffle genus, originally described from Europe. Color is an important diagnostic character for the species in this genus, and is naturally, if unfortunately, obscured in dried herbarium specimens. Therefore, some notable experts have understandably misidentified some of the species in herbaria. This study was part of a larger effort to use molecular phylogenetic analyses followed by morphological study to sort the relationships and species limits within Pachyphlodes. One clade of Pachyphlodes that we refer to here as the /nemoralis clade was previously unrecognized for its unique spore ornamentation of coalesced spine tips present in all species in this clade studied to date. A North American species was misidentified as P. melanoxanthus, while a European species was misidentified as P. citrinus, or P. ligericus. Here we describe these two species in the /nemoralis clade as P. pfisteri from North America and P. nemoralis from Europe. We also link a mitosporic form to P. pfisteri, and revisit the concept of the mitosporic form called Glischroderma. We dedicate this paper to Richard P. Korf, who’s work on pezizalean anamorphs inspired this study.
puce Novel Tuber spp. (Tuberaceae, Pezizales) in the Puberulum Group from Mexico PDF
  Guevara-Guerrero G., Bonito G., Cázares-González E., Healy R., Vilgalys R., Trappe J. 367-374
Summary: Recent taxonomic and molecular studies on Tuber in North America have revealed several new species. Here we propose Tuber bonitoi, T. brunneum, T. pseudoseparans and T. tequilanum as new species. These species are described from Mexico and differ in a combination of morphologically features including ascospore size, pellis cell size, peridium thickness and ascoma color. These new taxa have phylogenetic affinity to Tuber separans, described from the United States. Phylogenetic placement of these novel Tuber species in the /puberulum clade are presented.
puce Contribución al conocimiento de la micobiota de las Islas Canarias (España) IV. Ascomycetes PDF
  Ribes M.Á., Negrín R., Quijada L., Beltrán-Tejera E. 375-393
Summary: 16 species of Ascomycetes collected in the Canary Islands are studied and described. Four genera are reported for first time in the archipelago: Kompsoscypha, Marcelleina, Plicaria and Sclerotinia (K. chudei, M. benkertii, P. carbonaria and S. sclerotiorum). Six species are new reports for the islands: Peziza succosa, Plectania ericae, Scutellinia crinita, Spathularia nigripes, Tricharina praecox and Trichophaea abundans. We widened the knowledge distribution of six species previously reported: Adelphella babingtonii, Plicaria endocarpoides (previously reported as Peziza endocarpoides), Pseudolachnea hispidula and Lamprospora maireana (La Gomera), Geopora clausa and Peziza succosella (Tenerife).
puce Four new species of Crocicreas (Helotiales, Leotiomycetes) from China PDF
  Zheng H.D., Zhuang W.Y. 394-402
Summary: Crocicreas species from China are reviewed and nine species are accepted. Four of them with unique set of specific morphological characteristics are described as new: C. boreosinicae, C. korfii, C. minisporum, and C. xinjiangensis. Crocicreas boreosinicae, C. korfii and C. xinjiangensis grow on herbaceous stems, and C. minisporum is on decorticated wood. An apical ring of the Hymenoscyphus type occurs in Crocicreas boreosinicae, C. korfii and C. minisporum, and the apical ring of C. xinjiangensis appears J-. Crocicreas albidum is recorded for the first time from China. Descriptions and illustrations of the new species are provided. A key to the known species of the genus in China is given.

This survey of the genus Hypoxylon in the French West Indies is based on the material collected during an ongoing mycological inventorial project initiated in 2003, including field trips usually carried out annually, between June and November. Previous records of Hypoxylon from these islands found in literature are analyzed and discussed, and only two species are retained as reliably identified in 1996, viz.: H. musceum and H. ochraceum. The thirty-seven additional taxa collected during these field trips bring up to thirty-nine the number of Hypoxylon taxa known from Guadeloupe and Martinique. These thirty-nine taxa are described, illustrated in colour and their taxonomic status is commented. They include seven taxa recently described as new in 2010, 2012 and 2015, viz.: H. cypraeisporum, H. griseobrunneum, H. isabellinum, H. laminosum, H. lateripigmentum, H. pulicicidum and H. sclerophaeum var. parvisporum and six new species described in this article, viz.: H. arawakianum, H. dussii, H. ochraceoglobosum, H. sepiaceum, H. sofaiense and H. subtrugodes. Seventeen known species are recorded for the first time from Guadeloupe or Martinique, viz.: H. aeruginosum, H. brevisporum, H. erythrostroma, H. fendleri, H. haematostroma, H. hypomiltum, H. investiens, H. lenormandii, H. monticulosum, H. munkii, H. pelliculosum, H. rickii, H. rubellum, H. rugulosporum, H. samuelsii, H. subgilvum and H. tortisporum. Finally seven collections that could not be unequivocally equated to known species are given the following provisional names referring to the most resembling known species viz.: H. cf. cinnabarinum sp1, H. cf. cinnabarinum sp2, H. cf. duranii, H. cf. dieckmannii, H. cf. hypomiltum, H. cf. pilgerianum sp1 and H. cf. pilgerianum sp2. A dichotomous identification key to the Hypoxylon spp. known from the French West Indies is proposed
