Vol. 7 - Fascicule 1 - Février 2015 (en ligne 12/02/2015)

puce Varicosporella, a new aquatic genus in the Nectriaceae from France PDF
  Lechat C., Fournier J. 1-8
Summary: Varicosporella aquatica gen. and sp. nov. is described and illustrated based on six collections on submerged wood in South of France. A fusarium-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 species in 22 genera of Hypocreales including 16 genera in the Nectriaceae. It is primarily characterized by obpyriform, greyish yellow to pale orange nonstromatic ascomata, short-ribbed ascospores and freshwater habitat.
puce Three distinctive neotropical species of Hypoxylon (Xylariaceae) with purple KOH-extractable pigments, including two new taxa H. cypraeisporum sp. nov. and H. sclerophaeum var. parvisporum var. nov. PDF
  Fournier J., Lechat C. 9-21
Summary: Three species of Hypoxylon collected in the French West Indies that release violaceous to purple KOH-extractable pigments are described and compared with their known relatives. Two of them exhibit a combination of morphological characters that supports their status of new taxa as H. cypraeisporum and H. sclerophaeum var. parvisporum. The former is diagnosed by black rosellinioid stromata and ascospores with conspicuously pitted epispore and the latter by its ascospores significantly smaller than in the typical variety. Two ancient herbarium specimens of H. sclerophaeum have been studied for comparison and are illustrated. The third species dealt with, occurring on bamboo, appeared conspecific with H. rugulosporum, a species known from Papua New Guinea, based on examination of the isotype and reinterpretation of some of its morphological characters. Hypoxylon rugulosporum is recorded here for the first time from the Neotropics. An updated dichotomous key to the Hypoxylon spp. with purple KOH-extractable pigments is provided.
puce Preliminary phylogenetic and morphological studies in the Plectania melastoma lineage (Ascomycota, Pezizales) PDF
  Carbone M., Loizides M., Alvarado P. 23-29
Summary: Phylogenetic studies conducted on one collection from Greece and two from Cyprus, the latter morphologically matching Plectania zugazae and Plectania melastoma respectively, reveal that the delimitation of these two species is still far from clear. The authors choose to keep the two species separate on phylogenetic and microscopic basis only. The presence of P. zugazae is confirmed for the first time for Cyprus and Greece and only for the second time worldwide. Useful macro- and microscopic pictures are provided and a tentative key of the accepted Plectania species is proposed.
puce Typification of Peziza sicula  Open Access PDF
  Agnello C., Baglivo A., Carbone M. 30
Summary: The authors revise their typification of Peziza sicula made in a previous article, in order to avoid conflict with ICN rules.
puce Kirschsteiniothelia thujina (Peck) D. Hawksw. (Kirschsteiniotheliaceae), reported from Europe for the first time PDF
  Zhang Y., Fournier J. 31-37
Summary: A dothideomycete repeatedly collected on stubs of dead branches of Abies alba in the French Pyrénées and once on the Spanish side of the Pyrénées was identified as Kirschsteiniothelia thujina based on morphological and ecological characters. This fungus was known from North America and had not been reported from Europe. A sample was isolated in artificial culture and three loci of genes sequenced. A phylogenetic analysis based on the results confirmed its placement in Kirschsteiniothelia and revealed its affinities with other taxa known in that genus. The peculiar ecology of K. thujina is briefly commented.

Several recent collections of Cupulina montana from mountainous regions of France, Switzerland and Austria are reported.
puce An update of Podospora sect. Podospora, with first descriptions from Italy of P. appendiculata and P. perplexens PDF
  Doveri F. 45-53
Summary: A survey of coprophilous fungi from Italy has allowed the author to recognise nineteen Podospora species, three (P. fimiseda, P. appendiculata and P. perplexens) belonging to section Podospora, whose main morphological features are mentioned and also examined in the light of recent molecular studies. P. appendiculata and P. perplexens are described for the first time from Italy and compared with P. fimiseda, which has frequently been collected and described by the author. The three species are also compared with others in sect. Podospora, and a key to the section is provided. Species currently excluded from sect. Podospora are also discussed.

puce New, rarely recorded and unsettled species of Hypoxylon (Xylariaceae) from French Guiana PDF
  Fournier J., Lechat C. 63-96
Summary: In June 2012, a field trip carried out over two weeks in two different localities in French Guiana resulted in a collection of 256 specimens of pyrenomycetes, mostly Xylariaceae. Out of them 42 specimens of Hypoxylon were recorded, several of them could not be equated to known species. Specimens of Hypoxylon collected by C. Lechat during previous collecting trips in French Guiana in 2008 and 2010 are likewise included in this survey. As a result of the thorough morphological study of these specimens 13 taxa are presented herein, including six new species, H. aureolimbatum, H. leprieurianum, H. nudum, H. paracouense, H. rhombisporum and H. verruciperisporium that are described, illustrated and commented upon. H. aureolimbatum strikingly resembles the temperate species H. subticinense but besides its different geographical distribution it deviates in the combination of morphological differences of stromata, asci, ascospores and asexual morph associated on natural substrate; H. leprieurianum is segregated from Hypoxylon spp. with similar external morphology based on small equilateral ascospores with broadly rounded ends, a perispore indehiscent in KOH and a faint short germ slit; H. nudum is unique in having a stroma reduced to a black basal tissue and lacking stromatal pigments; Hypoxylon paracouense resembles H. duranii but deviates by different KOH-extractable pigments and smaller ascospores with a sigmoid germ slit; H. rhombisporum is diagnosed based on frequently rhomboid ascospores with laterally ridged epispore and several further morphological differences from the closely related H. rectangulosporum; H. verruciperisporium is unique in having a verrucose perispore. Four rarely recorded species are likewise described and illustrated: H. aeruginosum, H. musceum and H. trugodes that are recorded from French Guiana for the first time, and H. fusoideosporum that was only known from two collections in French Guiana and Guyana. Finally, two collection deviating respectively from H. cinnabarinum and H. hypomiltum and possibly different are described, for which no formal taxonomic decision can be made until the natural range of variations encountered in these taxa is clearly understood; furthermore, three specimens are tentatively referred to H. dieckmannii, a pantropical taxon that appears to be a complex of closely related species. The holotypes of H. duranii, H. musceum and H. rectangulosporum that were studied for comparison are likewise illustrated. A dichotomous key the Hypoxylon spp. known from French Guiana is provided. In conclusion, the use of new morphological characters to segregate Hypoxylon spp. is suggested and commented.

puce A new species of Ijuhya, I. fournieri, from French Guiana PDF
  Lechat C., Lesage-Meessen L., Favel A. 101-104
Summary: A detailed description of Ijuhya fournieri sp. nov. is presented based on two collections on dead palm leaves in French Guiana. The asexual state has been obtained in culture and sequenced. Molecular data indicate that it is an undescribed species of Ijuhya. A key to the species of Ijuhya with fasciculate hairs is provided.
puce Lachnea poiraultii (Pezizales), rediscovered after more than one hundred years PDF
  Van Vooren N., Lindemann U., Vega M., Ribes M.A., Illescas T., Matocec N., Kušan I. 105-116
Summary: Recent collections of a cup-fungus identified as Lachnea poiraultii Boud. from the Iberian and Istrian (Croatia) peninsulas provided the opportunity to investigate its modern taxonomic position. An examination of the type specimen of this taxon confirmed the determination of Croatian, Portuguese and Spanish collections. Based on the results of multi-gene phylogenetic analyses which placed L. poiraultii within the Pyronemataceae with no support of affiliation with another genus, and the study of microscopic features in the living state, the new genus Paratricharina is proposed to accommodate L. poiraultii. The morphological similarities and differences from the most closely related species are discussed. A full description and illustrations of P. poiraultii are also provided.
puce Spooneromyces laeticolor (Pezizales) nouveau pour la Franche-Comté PDF
  Moyne G., Moingeon J.-M., Moingeon S., Page C. 117-120
Summary: The authors describe and illustrate two collections of Spooneromyces laeticolor made on the same day in different places in the Franche-Comté (France). One of these collections is a pseudoalbino variety, initially identified as S. velenovskyi. A key of members of this genus is also provided.

Vol. 7 - Fascicule 4 - Juillet 2015 (en ligne 22/07/2015)

puce Bryocentria hypothallina (Hypocreales) – a new species on Metzgeria furcata PDF
  Nordén B., Gardiennet A., Priou J.-P., Döbbeler P. 121-124
Summary: Bryocentria hypothallina (Bionectriaceae, Hypocreales) is described as a new species. It grows necrotrophically on the liverwort Metzgeria furcata (Metzgeriales), causing bleached, insular infections. Ascomata are formed on the ventral side of the thalli and perforate them from below. The novel ascomycete species is recorded from France, Norway, and Spain. Thus, the obligately bryophilous genus Bryocentria now includes eight species. Our new species is characterized ecologically by its specialized microhabitat, and morphologically by having ascospores bearing tiny cyanophilous warts.

Vol. 7 - Fascicule 5 - Août 2015 (en ligne 21/08/2015)

puce The genus Hypoxylon (Xylariaceae) in Guadeloupe and Martinique (French West Indies) PDF
  Fournier J., Lechat C., Courtecuisse R. 145-212
Summary: 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.

Vol. 7 - Fascicule 6 - Novembre 2015 (en ligne 30/11/2015)

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

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
  Perić B., Grebenc T. 347-356
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

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.

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.

Since Psilocistella quercina was described in 1977, it is considered a doubtful taxon, and therefore not currently accepted. A bibliographic revision, together with recent studies on collections from France and the Canary Islands (Spain) are used to provide evidence about its relevance. A provisional key to the genus is also given

Hymenoscyphus sulphuratus is an uncommon species growing on conifer litter, but is typically found on Picea abies needles. As with many other historically described species, this name lacks a clearly defined type. The purpose of this note is to provide a type which covers all the features that agree with the protologue and our modern interpretation of this name
