Index Fungorum number: IF 518513
Facesoffungi number: FoF 06011
Fungicolous on the fruiting body of decayed Basidiomycetes. Asexual morph: Conidial fructifications developing as loosely floccose masses of white mycelium bearing robust conidiophores with yellowish spore masses. Conidiophores erect, with branches arranged in verticillate whorls, with 3–5 verticils, 2–4 branches producing conidiogenous cells formed from one point, sometimes in lateral position in a verticil of phialides. Phialides colorless, 20–45 × 3.5–5.0 (x̅ = 42 μm, n = 30), attenuating to 2.0–3.0 μm (x̅ = 2.4 μm, n = 30). Conidia hyaline, ellipsoidal, sometimes cylindrical, long clavate or fusiform, with protuberant hilum, (0–)1-septate, slightly constricted at the septum, smooth-walled, 14–22 × 5–8 μm (x̅ = 19 × 6.5 μm, n = 30). Sexual morph: Undetermined. (Description from Sun et al. 2019)
