Facesoffungi number: FOF 06029

MycoBank number: MB827516

 

Fungicolous on a fruiting body of Boletus sp. Asexual morph: Hyphomycetous. Mycelium partly superficial, developing as floccose masses of septate, branched, smooth and hyaline hyphae bearing robust conidiophores with white spore masses. Conidiophores hyaline, erect, flexuous, septate, smooth. With two types of conidiogenous cells phialidic and aleuriogenic. Type A: Phialides solitary or rarely in verticels, 40–90 × 2–3 μm (x̅ = 58 × 2.5 μm, n = 30), attenuating to 1.0–2.0 μm at their apices. Phialoconida acrogenous, hyaline, broadly fusiform, 1-spetate when mature, 6–10 × 3–4 μm (x̅ = 7.5 × 3.5 μm, n = 50). Type B: Aleuriogenic discrete, on short side branches. Aleurioconidia hyaline, globose to gourd shaped, 1-septate, constricted at septum, with upper bigger and lower smaller cells, with angular tubercles on surface, 10–15 μm (x̅ = 13 μm, n = 50) in diam. Sexual morph: Undetermined.  (Description from Sun et al. 2019)
