Sulcosporium
Sulcosporium Phook. & K.D. Hyde, in Ariyawansa et al., Fungal Diversity: 10.1007/s13225-015-0346-5, [51] (2015).
Index Fungorum number: IF 551328; Facesoffungi number: FoF 00894, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Pathogen on grasses, causing necrotic leaf spots. Sexual morph: Ascomata solitary, scattered, immersed, globose to subglobose, uniloculate, membranous, with minute central papilla erumpent through host surface, ostiolate. Peridium thin, composed of several layers of thick-walled, brown to dark brown, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium comprising dense, 2–4 μm wide, cellular pseudoparaphyses, anastomosing at the apex, embedded in mucilaginous matrix. Asci 8-spored, bitunicate, fissitunicate, broadly fusiform to clavate, saccate or ampulliform, with a short blunt pedicel, apically rounded, with well-developed ocular chamber. Ascospores overlapping bi- to tri-seriate, initially hyaline, becoming very pale brown, ellipsoidal to fusiform, or slightly clavate, uniseptate. Asexual morph: Unknown (adapted from Ariyawansa et al. 2015).
Type species: Sulcosporium thailandicum Phook. & K.D. Hyde
Notes: Sulcosporium resembles Mixtura in causing leaf spot disease on Poaceae and having pseudoparaphyses with saccate asci (Eriksson & Yue 1990, Phookamsak et al. 2014) but differs in having two-celled ascospores, while Mixtura has muriform ascospores. Sulcosporium is a distinct and well-supported genus in Halotthiaceae. Molecular markers available for Sulcosporium are ITS, LSU, RPB2 and SSU.
