Sporormiaceae Munk, Dansk bot. Ark. 17 (no.1): 450 (1957).
MycoBank number: MB 81414; Index Fungorum number: IF 81414; Facesoffungi number: FoF 06565, 164 species.
Saprobic on wood, plant debris, soil, dung and exceptionally endophytic on various substrates. Sexual morph: Ascomata immersed to erumpent or superficial, globose to pyriform, solitary or gregarious, scattered, perithecioid or cleistothecioid, ascolocular pseudothecia, dark pigmented, membraneous or coriaceous. Peridium smooth or hairy, dark-pigmented cells of textura angularis, outermost cells thick-walled. Hamathecium comprising abundant cellular pseudoparaphyses, lacking periphyses. Asci usually 8–spored, fissitunicate, J–, clavate, globose or cylindrical, usually with a pedicel, apical apparatus scarcely developed, non-refractive, with a narrow endotunica. Ascospores often partly overlapping inside the asci, 1–3-seriate, sometimes fasciculate or crowded, oval to cylindrical, dark brown, exceptionally one-celled, usually septate and poly-celled, muriform, thick-walled, smooth, exceptionally ornamented, constricted at septa and fragmenting into part-spores at maturity, often with germ slits, with or without surrounded by a mucilaginous sheath. Asexual morph: Coelomycetous. Conidiomata subglobose, immersed, dark brown. Pycnidial wall dark brown to light brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, hyaline, oblong to clavate. Conidia oblong, suboboviod, hyaline to brown, 1-transverse septum.
Type – Sporormia De Not.
Notes – Sporormiaceae was established by Munk (1957) with Sporormia as the type genus. The members of this family are known as saprobic on dung, plant debris, soil, wood or exceptionally endophytic (Hausmann et al. 2002, Burney et al. 2003, van Geel et al. 2003, Kruys & Wedin 2009, Gonzalez-Menendez et al. 2017). Barr (1987b) synonymized Sporormiaceae under Phaeotrichaceae. However, Phaeotrichaceae was considered as members of Sordariales based on its unitunicate asci, thus the family status of Sporormiaceae was reinstated as an independent family. In Barr (2000), coprophilous bitunicate fungi were classified into three families based on their morphology; these are Delitschiaceae, Phaeotrichaceae and Sporormiaceae. The robust phylogenetic analyses confirmed that Delitschiaceae, Phaeotrichaceae and Sporormiaceae represent a distant relationship (Kruys et al. 2006, Schoch et al. 2009a, Liu et al. 2017a). Sporormiaceae comprises nine genera, Chaetopreussia, Forliomyces, Pleophragmia, Preussia, Sparticola, Sporormia, Sporormiella, Sporormurispora and Westerdykella.
