MycoBank number: MB 7885; Index Fungorum number: IF 7885; Facesoffungi number: FoF 10359; 26 morphological species (Species Fungorum 2021), 22 species with molecular data.

Epiphytic, saprobic and pathogenic on a range of hosts worldwide. Colonies mostly growing slowly, pale grey-brown in the center, loose, cottony, woolly-velvety, margin entire, flat, straight or sharp, dark brown to olivaceous black, reverse olivaceous black, somewhat moist. Vegetative hyphae hyaline initially, pale brown in older hyphae, septate, constrictions at the septa, straight or undulate, smooth-walled, guttulate or aguttulate, with or without oil droplets. Sexual morph: Ascomata scattered, subglobose to globose, dark brown, glabrous, thick-walled, ostiolate or ostiole inconspicuous, with or without dark superficial hyphae. Wall of ascoma multi-layered, comprising brown to hyaline cells of textura angularis and textura globulosa. Asci 8-spored, bitunicate, ellipsoidal to cylindrical, ovoid to ampulliform, with a short pedicel. Ascospores 2–3-seriate, ellipsoidal to fusiform, hyaline, 1–3 septate, not constricted at the septa, narrowly rounded at the ends, with or without a guttule in each cell (Yang et al. 2018, Phookamsak et al. 2019). Asexual morph: Hyphomyctous. Conidiophores absent or rarely reduced to a short cell, basal to the conidiogenous cells. Conidiogenous cells enteroblastic, phialidic. short cylindrical to flask-shaped, intercalary, lateral or terminal, sometimes arising at short side branches of hyphae, with indistinct sessile collarettes or short and flaring to funnel-shaped collarettes, sub-hyaline to pale olivaceous brown, producing subsequent conidia in more or less sympodial order, thin-walled. Conidia aggregated, oblong-fusoid or oblong-ovoid, 1−multi-septate, constrictioned at the septa, hyaline to brown, straight or curved, smooth-walled, guttulate or aguttulate, with or without oil droplets, without a gelatinous sheath or appendages. Spermatial state absent. Chlamydospores absent.
