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.

puce Xylaria violaceorosea sp. nov. (Xylariaceae), a distinctive species discovered in Spain  
  Fournier J., Román A., Balda J., Rubio E. 35-39
Summary: Xylaria violaceorosea is described as a new species based on the combination of distinctive macroscopic and microscopic characters. It is a lignicolous Xylaria with stromata roughly recalling those of X. hypoxylon but with a purplish pink outer layer that yields olivaceous yellow pigments in 10% KOH and relatively large ascospores provided with gelatinous secondary appendages.

puce Species diversity of Genea (Ascomycota, Pezizales) in Europe  
  Alvarado P., Cabero J., Moreno G., Bratek Z., Van Vooren N., Kaounas V., Konstantinidis G., Agnello C., Merényi Z., Smith M.E. 41-51
Summary: Here we revisit the species diversity within the genus Genea in Europe. Nine new species are proposed: Genea brunneocarpa, G. compressa, G. dentata, G. fageticola, G. oxygala, G. pinicola, G. pseudobalsleyi, G. pseudoverrucosa, and G. tuberculata to accommodate new collections that do not match any previously described taxa. The new species are described with accurate morphological and ecological data. Genea lobulata is also proposed as a new combination to elevate the previously recognized variety, Genea sphaerica f. lobulata, to the species level. Useful macroscopic images and spore drawings of all ten new taxa are included to help discriminate them from closely related species.

puce Two new species of Hypoxylon (Xylariaceae) from French Central Pyrenees occurring on Fagus sylvatica  
  Fournier J. 53-60
Summary: In the course of an extensive survey of Xylariaceae in the French Central Pyrenees over the last fifteen years two undescribed species of Hypoxylon were recently discovered, both on Fagus sylvatica. Based on the combination of remarkable ecological and morphological characters that does not match known taxa, both species are recognized as new to science. Hypoxylon cazenavei is distinctive in having brown vinaceous effused-pulvinate stromata turning fuscous, with tubular to lanceolate perithecia and yellow brown KOH-extractable pigments. Hypoxylon invadens is diagnosed on its occurrence on aborted primordia of H. fragiforme, its fulvous stromata soon turning shiny black with strongly exposed perithecial contours, slightly carbonaceous subsurface and yellow brown KOH-extractable pigments.
puce Découverte de Lazuardia lobata (Pezizales) sur l’île de Mayotte  
  Van Vooren N., Pélissier M. 61-63
Summary: Lazuardia lobata is an uncommon discomycete, known from tropical or subtropical areas, rarely cited in literature. A late discovery of this species on the Island of Mayotte provides an opportunity to propose a full description, along with microscopic drawings and colored illustrations. A brief history of this taxon is provided and its systematics is also discussed.

Auteur: Van Vooren N.
Date: 03/20/2014
Language:

Urnula padeniana (Pezizales) sp. nov. and the type study of Bulgaria mexicana
Auteur: Carbone M., Agnello C., Parker A.
Date: 03/20/2014
Language:
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

The genus Ascodesmis (Pezizales) in Norway
Auteur: Kristiansen R.
Date: 03/20/2014
Language:
This report presents the four species of Ascodesmis (Ascomycota, Pezizales) recorded in Norway, and an updated map of their distribution. All are coprophilous, and occur on dung of both carnivorous and herbivorous animals. The species are illustrated by scanning electronmicrography of their ascospores, which is the main distinguishing character at species level. Systematics are briefly discussed, and Ascodesmis is genetically close to the genus Eleutherascus

The genus Otidea. VI. Otidea felina and its interpretations
Auteur: Van Vooren N., Carbone M.
Date: 03/20/2014
Language:
Otidea felina is one of the oldest names in the genus Otidea. Described by Persoon with only a short diagnosis and without illustration, it has been interpreted in several ways by successive authors. Until now, most collections of Otidea with fulvous or ochraceous tinges and with small spores have been named O. felina, perpetuating the confusion around this name. To clarify the situation, we had the opportunity to revise the type collection of Peziza felina Pers. as well as other collections named O. felina. We discovered that the holotype is, in fact, an immature specimen of O. alutacea. The identification of other revised collections is also revealed
