Paraophiobolus
Paraophiobolus Phookamsak, Wanas., & K.D. Hyde, in Phookamsak et al., Fungal Diversity 87: 318 (2017).
Index Fungorum number: IF 553920; Facesoffungi number: FoF 03798, 3 morphological species (Species Fungorum 2022), 3 species with molecular data.
Saprobic on Poaceae. Sexual morph: Ascomata immersed to erumpent through epidermis of host, light brown at the base, brown to dark brown towards the apex, scattered, solitary to gregarious, globose to subglobose, uniloculate, glabrous, ostiolate, papillate. Papilla mammiform to oblong, with rounded to truncate apex, composed of several layers of dark brown to black cells, arranged in a textura angularis to textura prismatica, glabrous, ostiole central, without periphyses. Peridium thick-walled, composed of brown to dark brown, thick-walled cells, arranged in a textura angularis. Hamathecium comprising numerous, broad, branched, septate, cellular pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, cylindrical to cylindric-clavate, with short furcate pedicel, apically rounded, ocular chamber clearly visible when immature. Ascospores fasciculate, scolecosporous, with rounded ends, tapering towards the lower cells, hyaline to pale yellowish, or yellowish green at maturity, slightly curved near the apex, multi-septate, with a swollen cell, slightly constricted at the septum, not separating into part spores, smooth-walled, with or without terminal appendages. Asexual morph: Unknown (adapted from Phookamsak et al. 2017).
Type species: Paraophiobolus arundinis Phukhamsakda, Phookamsak, Wanas., Camporesi & K.D. Hyde
Notes: Paraophiobolus resembles Ophiobolus in having scolecospores, with a swollen cell. But, Paraophiobolus is phylogenetically distant from Ophiobolus and is a distinct genus. Molecular markers available for Paraophiobolus include ITS, LSU, SSU, and TEF-1.
