Phomatosporaceae Von Arx.
Index Fungorum number: IF 552312; Facesoffungi number: FoF 02486
74 species. Saprobic on submerged wood or decaying twigs in both terrestrial and aquatic habitats.
Sexual morph: Ascomata perithecial, solitary, seldom gregarious, immersed or gradually becoming erumpent with age, subglobose to globose, light brown to dark brown or black, coriaceous, occasionally developing beneath a small blackened clypeus, ostiolate, with a short papilla or rarely with a rostrate or cylindrical, hyaline neck, central or eccentric. Ostiole periphysate. Peridium composed of small, brown pseudoparenchymatous cells. Paraphyses filamentous, aseptate or septate, tapering. Asci 8-spored, unitunicate, cylindrical or oblong-fusiform, thin-walled, shortpedicellate or sessile, J- ring in the ascal apex. Ascospores overlapping uniseriate to rarely biseriate, hyaline, ellipsoidal to fusiform, aseptate or septate, not constricted at the septum, at times biguttulate, with striations or appendages or a sticky mucilaginous sheath (Senanayake et al. 2016). Asexual morph: sporothrix-like (adapted from Rappaz 1992, Fournier & Lechat 2010, Senanayake et al. 2016).
Type genus: Phomatospora Sacc
Notes: After von Arx (1951) invalidly established Phomatosporaceae, Senanayake et al. (2016) formally introduced the family to accommodate Phomatospora, Lanspora and Tenuimurus. Three genera, based on LSU, SSU and ITS phylogeny, formed a clade distantly related to other existing orders in the Diaporthomycetidae, for which, the new order Phomatosporales, was established (Senanayake et al. 2016).
