MycoBank number: MB 839292; Index Fungorum number: IF 839292; Facesoffungi number: FoF 11517;

Etymology: Name refers to its morphological similarity to Scirrhia.

Ascomata pseudothecial, gregarious, stromatic, immersed, becoming erumpent, opening by longitudinal split of epidermis, arranged parallel to the culm axis, black, thick- and smooth- walled, multi-locular, loculi in one row and one level, globose, black, soft, ostiole central, indistinct. Peridium multi-layered, of textura angularis-prismatica, inner layers hyaline, outer layers dark brown. Pseudoparaphyses numerous, partly evanescent, multi-celled, moniliform to cylindrical, branched, anastomosing. Asci 8-spored, subclavate to cylindrical, apically rounded with ocular chamber, pedicel short, broad and furcate, bitunicate, fissitunicate. Ascospores straight to slightly curved, cells cylindrical, ends rounded, upper cell enlarged towards median septum, at times with lateral swelling just above the septum hyaline, thin- and smooth-walled, constricted at septum, cytoplasm aggregated in middle region, causing ends to appear very thick-walled, apex more prominently so than basal end. Conidiomata pycnidial, globose, brown, with central ostiole; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells lining inner cavity, hyaline, smooth, doliiform to ampulliform, phialidic. Conidia solitary, hyaline, smooth, prominently guttulate, medianly 1-septate, subcylindrical to obovoid, ends obtuse.
