Ascomycete.org - Volume 5

Fascicule 1 - Janvier 2013 (mise en ligne 3/01/2013)

puce Phylogenetic studies in the family Sarcosomataceae (Ascomycota, Pezizales)  Open Access PDF
  Carbone M., Agnello C., Alvarado P. 1-12
Summary: New phylogenetic studies focused on the family Sarcosomataceae support the independence of the genera Plectania, Pseudoplectania, Donadinia, Sarcosoma, Galiella and Urnula. Galiella is restricted to the temperate species, while the tropical taxa seem to be more related to the family Chorioactidaceae, and are here accomodated in the prioritary genus Trichaleurina. The lineage including the type species of Urnula is here shown to include also several morphologically deviant species. The genus Pseudosarcosoma is here proposed to accommodate Sarcosoma latahensis/Plectania latahense in the family Chorioactidaceae, since this lineage is not related to the type species of the genus Sarcosoma, S. globosum.
puce Urnula padeniana (Pezizales) sp. nov. and the type study of Bulgaria mexicana  Open Access PDF
  Carbone M., Agnello C., Parker A. 13-24
Summary: Urnula padeniana is described as new although it is a common northwestern American species known for years as Sarcosoma mexicanum or Plectania mexicana. A morphological in-depth study of this species is reported. The type of Bulgaria mexicana is also revised, and turns out to be a different species, being a member of the Urnula campylospora complex. The new combination Urnula mexicana is proposed. Color pictures of fresh and dried specimens, microscopic morphology, and a black and white plate of hymenial elements are included. Related or similar species are also discussed.
puce Notes on Urnula campylospora (Pezizales)  Open Access PDF
  Carbone M., Agnello C. 25-32
Summary: The authors present a detailed morphological study of Urnula campylospora (Berk.) Cooke based on a Tasmanian collection and on four New Zealand specimens housed in the New Zealand Collection of Fungi and Plant Pathogens (PDD). Nomenclatural and taxonomical notes are provided along with photographs and drawings of microscopic and macroscopic features.
puce A type study of Pseudoplectania stygia (Pezizales)  Open Access PDF
  Carbone M. 33-38
Summary: The original material of Peziza stygia Berk. & M.A. Curtis, housed in the Farlow Herbarium (FH) of Harvard University and in the herbarium of the Royal Botanic Gardens of Kew (K), was revised to confirm its taxonomic position in the genus Pseudoplectania Fuckel. Color pictures of dried specimens and microscopic characters are also provided.
puce Wolfina aurantiopsis, a rare species in the family Chorioactidaceae (Pezizales)  Open Access PDF
  Agnello C., Carbone M., Braaten C. 39-45
Summary: A detailed morphological study of the rare ascomycete Wolfina aurantiopsis (Ellis) Eckblad is presented after the thorough study of two collections from Tennessee (USA). Macroscopic and microscopic color photographs as well as line drawings are included. Notes regarding taxonomy and nomenclature of W. aurantiopsis and related species are proposed.
puce Pseudoplectania melaena (Pezizales): taxonomical and nomenclatural note  Open Access PDF
  Van Vooren N., Moyne G., Carbone M., Moingeon J.-M. 47-52
Summary: Pseudoplectania melaena (Fr.) Sacc. (= P. vogesiaca) is a widespread species, growing on dead wood of conifers (Abies sp. in Europe), during spring, in mountainous areas. In some regions, it is considered as rare or uncommon, that’s why we propose a full description of this taxon based both on recent collections and ancient specimens housed in Persoon’s herbarium (L). Taxonomical and nomenclatural aspects are provided, and a lectotype is designated. Although limited, the risk of confusion with other species of the genus is discussed.
puce Notes on Urnula hiemalis Nannf.  Open Access PDF
  Carbone M., Agnello C. 53-61
Summary: The authors report a detailed morphological study of Urnula hiemalis, based on recent Finnish collections. Colour pictures of fresh and dried material, microscopy, as well as B/W drawings are provided. The taxon is also compared with the closest species like U. craterium, U. groenlandica and U. brachysperma.

Fascicule 2 - Mars 2013 (mise en ligne 25/03/2013)

puce Contribution à l’étude des discomycètes. Version 2013  Open Access PDF
  Dougoud R. 63-89
Résumé : cette « Contribution à l’étude des discomycètes, version 2013 » a pour but une compréhension plus aisée de la classe des Pezizomycetes. Elle traite les caractères nécessaires à la connaissance des genres et des espèces, de leur mode de reproduction à leurs habitats, de leur récolte aux spécificités macroscopiques et microscopiques permettant leur identification, jusqu’à leur mise en herbier. Hormis les caractères macroscopiques, un accent particulier a été mis pour permettre d’atteindre une bonne mise en évidence des éléments de la microscopie, indispensables à une identification précise des espèces. Les commentaires sont illustrés de photographies et de nombreux dessins.

Fascicule 3 - Mai 2013 (mise en ligne 18/05/2013)

puce Patinella hyalophaea Sacc. – Rediscovered in New Brunswick, Canada  Open Access PDF
  Baral H.-O., Carter A. 91-96
Summary: Patinella hyalophaea (type species of Patinella) is redescribed from the type material from Italy and from a recent collection from Canada. Further records of this apparently rare species could not be traced. Its ecological amplitude involves decorticated branches of both angio- (Fagus) and gymnosperms in montane, humid beech forests mixed with conifers. A possible adaptation to flooding by streams is discussed. The affinities of Patinella within the Helotiales are unsettled, whereas an earlier proposed relation to the Orbiliomycetes based on the capitate paraphyses is considered as quite improbable.
puce Beiträge zur Erforschung der Pilzflora Äthiopiens. Operculate Discomyceten, Teil 1  Open Access PDF
  Lindemann U. 97-103
Summary: Based on recent collections from Ethiopia, two species of the genus Octospora are presented. O. kilimanjarensis J. Moravec is reported for the first time for Ethiopia and the second time worldwide. Due to the difficulties in assigning the second Octospora sp. to an existing taxon it is only described and illustrated.
puce Une espèce à rechercher : Octospora affinis Benkert & L.G. Krieglsteiner (Pezizales), nouvelle pour la Franche-Comté  Open Access PDF
  Chaillet P., Moyne G. 105-107
Résumé : les auteurs décrivent et illustrent Octospora affinis à partir de récoltes très récentes. L'espèce est enregistrée pour la première fois en Franche-Comté.

Fascicule 4 - Octobre 2013 (mise en ligne 20/10/2013)

puce Hymenoscyphus serotinus and H. lepismoides sp. nov., two lignicolous species with a high host specificity  Open Access PDF
  Baral H.-O., Bemmann M. 109-128
Summary: Hymenoscyphus serotinus is a rather well-known and common species which, in its restricted sense, was so far recorded only within Europe, where it fruits exclusively in late autumn and early winter on externally blackened wood of twigs and thin branches of Fagus. Despite its rather characteristic, long and slender, curved (comma-shaped) ascospores, the species was not rarely confused in the past with other European lignicolous taxa: either with H. calyculus, from which it was thought to be insufficiently separated, or with an undescribed species that likewise fruits in late autumn on blackened wood though of Carpinus, and is here described as a new species, H. lepismoides. This differs from H. serotinus in longer and wider, straighter spores, which are provided by prominent terminal setulae, and also in the absence of croziers at the ascus base. Apart from this and some other misinterpretations, Hymenoscyphus serotinus was considered by various authors as a foliicolous taxon, mainly outside Europe. One of these records, on unidentified skeletonized leaves from Jilin (China), was reinvestigated in the present study and considered to be related to, though not conspecific with, H. vacini, a European species confined to skeletonized leaves of Acer. The identity of this and other extra-European records remains to be resolved by future studies.
puce Micropeziza filicina sp. nov. (Helotiales), a fern inhabiting species of intermediate generic position, with an emendation of the genus Micropeziza Fuckel  Open Access PDF
  Helleman S., Lindemann U., Baral H.-O., Yeates C. 129-136
Summary: Micropeziza filicina is described as a new species and the generic boundaries between Calloriella, Calycellina, Crustomollisia, and Micropeziza are discussed. Due to morphological similarities between the genera, and the intermediate position of this species, the amalgamation of Calloriella and Crustomollisia with Micropeziza is proposed. For Calloriella umbrinella, Calycellina castanea and Orbilia mollisioides new combinations in Micropeziza are proposed, and Allophylaria soederholmii is included within the synonymy of C. umbrinella.

Fascicule 5 - Décembre 2013 (mise en ligne 22/12/2013)

puce Studies in Trichaleurina (Pezizales). Type studies of Trichaleurina polytricha and Urnula philippinarum. The status of Sarcosoma javanicum, Bulgaria celebica, and Trichaleurina tenuispora sp. nov., with notes on the anamorphic genus Kumanasamuha  Open Access PDF
  Carbone M., Wang Y.Z., Huang C.L. 137-153
Summary: The original material of Trichaleurina polytricha and Urnula philippinarum housed in the Herbarium of the Swedish Museum of Natural History (S) was examined. The results of the morphological study prove they are synonyms of Trichaleurina javanica. The status of Sarcosoma javanicum and Bulgaria celebica are investigated, and a new species, Trichaleurina tenuispora, is proposed to replace one of the different interpretations of B. celebica. The anamorphic genus Kumanasamuha is discussed as well. Color pictures of dried and fresh specimens and microscopic characters are provided.
