Bjerkandera ecuadorensis Y.C. Dai, Chao G. Wang & Vlasák, sp. nov.2021

MycoBank: 538578

Type.:Ecuador, Pichincha Province, volcan Pasochoa, 3300 m, VI. 2019, J. Vlasák Jr. JV 1906/C16-J (holotype in PRM, isotypes in JV and BJFC032992).

Description:

Sexual morph: Basidiomata. Annual, pileate, soft corky, without odor or taste when fresh, be coming corky when dry, projecting up to 4 cm, 5 cm wide and 1.3 mm thick at base. Pileal surface pinkish-buff to buff, glabrous, faintly zonate, margin blunt. Pore surface grey to dark-brown, becoming almost black when touched or bruised; sterile margin distinct, up to 2 mm wide; pores round to angular, 7–9 per mm; dissepiments thin, entire. Context buff-yellow, slightly fibrous to corky, up to 1 mm thick. Tubes con colorous with the pore surface and darker than context, corky, up to 0.3 mm long, and with a distinct dark line between tubes and context. Tubes. Generative hyphae thin- to slightly thick-walled, rarely branched, subparal lel along the tubes to loosely interwoven, 2.5–3.8 μm in diam. Cystidia and cystidioles absent. Basidia clavate to barrel-shaped, with four sterigmata and a basal clamp con nection, 13–14.5 × 4.5–5.5 μm; basidioles of similar shape to basidia, but smaller. Basidiospores. Ellipsoid, hyaline, thin-walled, smooth, often with one or more guttules, CB–, IKI–, (3.8–)3.9–4.5 × 2.7–3 μm, L = 4.09 μm, W = 2.86 μm, Q = 1.43 (n = 30/1).
