Index Fungorum number: IF556756; Facesoffungi number: FoF06335; 1 morphological species; 1 species with sequence data.


Saprobic on dead sheaths of Miscanthus sinansis (Poaceae). Sexual morph: Ascomata immersed beneath blackened aggregated clypeus on the surface of dead sheath, loosely aggregated or rarely solitary; dark brown to black, globose to subglobose, slightly depressed, uniloculate with distinct centrally erumpent ostiole with periphyses, surrounded by distinct, shiny, black flanges the tissue spreading down along the papilla. Peridium comprising 4–5 cell layers of thin-walled, brown cells of textura angularis, inwardly lighter. Paraphyses filamentous, distinctly septate, embedded in a gelatinous matrix. Asci 8-spored, unitunicate, cylindrical, short pedicellate, slightly truncate at the apex with a wedge-shaped, J+, subapical ring. Ascospores overlapping uniseriate, brown, ellipsoidal, slightly tapering at the ends, equally 2-celled and guttulate at both cells, constricted at the septum, with striations, surrounded by a thick, hyaline mucilaginous sheath, parallel to the margin of the spore (Hyde et al. 2020). Asexual morph: Undetermined.



Type species: Alishanica miscanthii Karun., C.H. Kuo & K. D. Hyde, in Hyde et al., Mycosphere 11(1): 461 (2020)



Notes: Alishanica resembles Cainiaceae in having clypeate, ostiolate ascomata, unitunicate, cylindrical asci with J+ apical ring and ascospores with a number of longitudinal germ-slits resembling ridges. The genus has been shown to be phylogenetically well-supported with bayesian posterior probability (0.94 PP) and moderate maximum likelihood (53%) along with maximum parsimony (53%) support in Hyde et al. (2020).
