Haniomyces J.C. Xu, in Wanasinghe et al., Journal of Fungi 7(3, no. 180): 24 (2021).
Index Fungorum number: IF 837991; Facesoffungi number: FoF 11378, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on dead twigs and branches in terrestrial habitats. Sexual morph: Ascomata scattered, immersed to semi-immersed, subglobose to conical or shaped irregularly, glabrous, brown to dark brown ostiolate. Ostiole short papillate, black, smooth periphysate. Peridium comprises cells of textura angularis. Hamathecium comprises numerous, filamentous, branched, septate, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, clavate, with a pedicel, apically rounded with or without an ocular chamber. Ascospores overlapping biseriate, ellipsoidal to sub-fusiform, hyaline, one-septate, with small to large guttules in each cell, with the ends remaining rounded, surrounded by a distinct mucilaginous sheath. Asexual morph: Coelomycetous. Conidiomata sporodochial on PDA, globose, solitary or aggregated, semi-immersed, black, exuding yellow conidial masses. Conidiophores and conidiogenous cells were not observed in vitro. Conidia solitary, aseptate, globose to ellipsoid, with the hyaline becoming medium to golden brown, and finely verruculose (adapted from Wanasinghe et al. 2021).
Type species: Haniomyces dodonaeae Wanas. & Mortimer
Notes: Haniomyces is characterised by immersed to semi-immersed, subglobose to conical ascomata, short papillate, black, smooth periphysate ostiole, eight spored, bitunicate, fissitunicate, clavate asci and ellipsoidal to sub-fusiform, hyaline, one-septate ascospores. Haniomyces is morphologically and phylogenetically a distinct and well-defined genus in Teratosphaeriaceae. Molecular markers available for Haniomyces include ITS, LSU, SSU, Actin, BTUB, Calmodulin, RPB2 and TEF-1.
