Facesoffungi number: FoF 07484

Leotiomycetes, Leotiomycetidae, Medeolariales, Dermateaceae


Endophytic, saprobic or pathogenic on plant host in terrestrial habitat. Sexual morph: See Chen et al. (2016). Asexual morph: Conidiomata dark brown to black, acervular to stromatic, solitary, gregarious or confluent, immersed or erumpent, cylindrical to subglobose or conical, unilocular or multilocular, dehiscence irregular, but some species forming a massive erumpent stroma and dehisence by a large ostiole (P. pruinosa and P. italica), thick-walled. Conidiomata wall composed of thick-walled, hyaline to pale brown cells of textura angularis. Conidiophores reduced to conidiogenous cells or present. Conidiogenous cells enteroblastic, phialidic discrete or integrated, indeterminate, proliferating percurrently, cylindrical to subcylindrical, hyaline. Macroconidia oblong to cylindrical, hyaline, straight, apex obtuse, base abruptly tapered to a distinct truncate scar, aseptate, smooth, thick-walled, guttulate or eguttulate. Microconidia present or absent, hyaline, cylindrical, rounded at the apex, truncate at the base, unicellular, smooth, thin-walled, contents granular (Sutton 1980, Verkley 1999).


Type species: Pezicula carpinea (Pers.) Tul. ex Fuckel, Jb. nassau. Ver. Naturk. 23-24: 279 (1870) [1869-70]


Notes: Since Pezicula was introduced, many species have been described under this genus (Verkley 1999, Abeln et al. 2000, Verkley et al. 2003, Johnston et al. 2004, Yuan and Verkley 2014). The asexual morph of Pezicula is associated with Cryptosporiopsis Bubák & Kabát., which was introduced in 1912 based on C. scutellata, the sexual morph of which is Pezicula ocellata (Yuan and Verkley 2014, Chen et al. 2016). Chen et al. (2016) revised the genus based on both morphology and phylogeny, designated an epitype for P. carpinea and delineated the boundary of the genus. Cryptosporiopsis was synonymized under this genus. There are 27 species accommodated in Pezicula, including a new species which is introduced in this paper.


Distribution: Austria, Belgium, Canada, China, Denmark, France, Germany, Italy, Norway, Poland, Portugal, Russia, UK, USA, Switzerland, The Netherlands (Grove et al. 1946, Abeln et al. 2000, Chen et al. 2016, this study).
