Saprobic on dead or decaying leaves of plants in terrestrial habitats. Sexual morph: Ascomata perithecial, immersed at the base, obpyriform, dark brown, with setae. Peridium composed of 3–5 layers of pale brown cells of textura prismatica. Paraphyses branched, septate. Asci 8-spored, unitunicate, cylindrical-clavate, short pedicellate, apex truncate with shallow ring. Ascospores biseriate, hyaline, ellipsoid to oblong, apiculate at ends with minute mucoid cap, smooth-walled, guttulate, becoming 1-septate and pale brown after discharge. Asexual morph: Conidiophores subcylindrical, macronematous, unbranched, erect, flexuous, thick-walled, rounded at apex, guttulate, multi-septate, pale brown to bark brown, smooth-walled. Conidiogenous cells enteroblastic, phialidic, subcylindrical, subhyaline, terminal, integrated. Conidia solitary, cylindrical-ellipsoid to clavate, rounded at apex, aseptate, hyaline, smooth-walled, guttulate, dry in mass (adapted from Tibpromma et al. 2018).

Notes: Malaysiascaceae was introduced by Tibpromma et al. (2018) to accommodate Malaysiasca which belong in Glomerellales. The family is similar to Australiascaceae, but the latter differs in having phialidic conidiogenesis with hyaline 0(–3)-septate conidia aggregated in slime or chains (Réblová et al. 2011).

Type species: Malaysiasca Crous & M.J. Wingf.
