Epiphytic, saprobic or pathogenic on a range of hosts worldwide. Colonies mostly growing slowly, pale grey-brown in the center, cream-colored, light mouse grey to dark grey, 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 or grey olivaceous when mature, 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 round at the ends, with or without a guttule in each cell (Yang et al. 2018, Phookamsak et al. 2019). Asexual morph: hyphomycetous. Conidiophores absent or rarely reduced to a short cell basal to the conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, short cylindrical to flask-shaped, ampulliform, 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 or triangular, 1–multi-septate or aseptate, constrictioned at the septa, hyaline to brown, straight or sometimes concave, smooth-walled, guttulate or aguttulate, with or without oil droplets, without a gelatinous sheath or appendages. Spermatial state absent. Chlamydospores absent.
Notes – Réblova et al. (2013) introduced Cyphellophoraceae Réblová & Unter. to accommodate the type genus Cyphellophora G.A. de Vries with eight species from Cyphellophora and six species from Phialophora Medlar based on morphology, secondary structure data and phylogenetic analysis which formed a distinct lineage within Chaetothyriales. Anthopsis was formally established in Cyphellophoraceae by Moussa et al. (2016). Thus, the definition of Cyphellophoraceae was extended to include flask-shaped or ampulliform phialides or phialide-like cells with indistinct sessile collarettes or short and flaring to funnel-shaped collarettes, and oblong-fusoid to oblong-ovoid or triangular conidia with or without septa. Currently, two sexual morph species are accepted, viz. Cyphellophora jingdongensis H. Yang & K.D. Hyde and C. filici Hongsanan et al. isolated from plant material (Yang et al. 2018, Phookamsak et al. 2019).
