puce Cheilymenia catenipila J. Moravec (Pezizales). Un rare discomycète coprophile découvert en Espagne et en France  
  Rubio E., Delpont M. 11-16

puce Phylogenetic and morphological studies in the genus Pseudoplectania (Ascomycota, Pezizales)  
  Carbone M., Agnello C., Alvarado P. 17-33
Summary: New phylogenetic studies focused on the genus Pseudoplectania confirm the independence of the already known species Pseudoplectania nigrella, P. melaena, and P. ericae, although there seems to exist a species complex around both P. nigrella and P. melaena. The status of Peziza spongiosa is discussed. In addition, molecular results support the independence of P. sphagnophila in the sense of European authors. However, the original diagnosis of the latter does not fit the modern concept of this species, and so P. episphagnum is proposed as a substitute for the species growing in bogs on Sphagnum spp. Finally, the new species P. affinis and P. tasmanica are proposed to accomodate material from New Zealand and Tasmania, respectively. A review on the remaining known species of the genus is also discussed.

Studies in Trichaleurina (Pezizales). Type studies of Trichaleurina polytricha and Urnula philippinarum. The status of Sarcosoma javanicum,...
Author: Carbone M., Wang Y.Z., Huang C.L.
Date: 12/22/2013
Language: EN
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

Hymenoscyphus serotinus and H. lepismoides sp. nov., two lignicolous species with a high host specificity
Author: Baral H.O., Bemmann M.
Date: 10/20/2013
Language: EN
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

Micropeziza filicina sp. nov. (Helotiales), a fern inhabiting species of intermediate generic position, with an emendation of the genus Micropeziza
Author: Helleman S., Lindemann U., Baral H.O., Yeates C.
Date: 10/20/2013
Language: EN
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

Patinella hyalophaea Sacc. – Rediscovered in New Brunswick, Canada
Author: Baral H.O., Carter A.
Date: 05/18/2013
Language: EN
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

Contribution à l’étude des discomycètes. Version 2013
Author: Dougoud R.
Date: 03/25/2013
Language: FR
The 2013 version of "Contribution à l’étude des discomycètes" aims at an easier comprehension of the Pezizomycetes. The necessary features to the knowledge of genera and species are delt with, such as reproduction cycle, habitats and collecting devices, along with macroscopic and microscopic specific studies facilitating their identification and the preparation of exsiccata. The study of microscopic features has been emphasized in order to enable an clear description of the necessary features for a precise species identification. A great number of drawings and photographs are given to illustrate the text
