Fungicolous, growing on the fruiting body of Fistulina sp. Asexual morph: Hyphomycetous. Mycelium partly superficial, composed of septate, loosely branched, floccose masses of white, hyaline hyphae bearing conidiophores and white spore masses. Conidiophores macronematous, mononematous, erect, septate, branched, with branches arranged in 1–3 verticillate whorls, hyaline, 200–300 × 4–6 μm (x̅ = 280 × 5.5 μm, n = 10). Phialides verticillate, determinate, terminal, 30–60 × 4–6 μm (x̅ = 42 × 5.5 μm, n = 50), attenuating to 1.0–2.0 μm at their apices, slightly tapering at the tip. Conidia acrogenous, holoblastic, broadly ellipsoidal, each with a broad, blunt basal apiculus and broadly rounded apex, 1–3-septate when mature, slightly constricted at the septa, thin-walled, smooth-walled, hyaline, 16–32 × 6–10 μm (x̅ = 27 × 8 μm, n = 50). Sexual morph: Undetermined. (Description from Sun et al. 2019)
