Elaphroporia ailaoshanensis
Elaphroporia ailaoshanensis Z.Q. Wu & C.L. Zhao 2018, in Wu et al., MycoKeys (29), 89 (2018).
Etymology. Ailaoshanensis (Lat.): referring to the locality (Ailaoshan) of the type specimens.
Diagnosis. This species is distinguished by the cream to yellow pore surface upon drying; pores angular, 7–9 per mm. Hyphal system monomitic; generative hyphae thick-walled bearing both clamp connections and simple septa, slightly amyloid, CB+. Basidiospores ellipsoid, hyaline, thin-walled, smooth, IKI–, CB–, 1.9–2.5 ×1.5–2 μm.
Basidiocarps. Annual, resupinate, easy to separate from substrate, soft corky when fresh, without odour or taste when fresh, becoming rigid and light-weight up on drying, up to 5 cm long, 3.5 cm wide, 4 mm thick at centre. Pore surface cream to pale yellow when fresh, turning to yellow upon drying; pores angular, 7–9 per mm; dissepiments thin, entire. Sterile margin narrow, cream, up to 1 mm wide. Subiculum thin, cream, corky, up to 0.2 mm thick. Tubes concolorous with pore surface, hard corky, up to 3.8 mm long.
Hyphal structure. Hyphal system monomitic; generative hyphae thick-walled, slightly amyloid, CB+; tissues unchanged in KOH.
Subiculum. Generative hyphae hyaline, thick-walled bearing both clamp connections and simple septa, simple septa more frequent than clamps, occasionally branched, interwoven, 3.5–5.5 μm in diam.
Tubes. Generative hyphae hyaline, thick-walled bearing simple septa only, occasionally branched, 3–5 μm in diameter. Cystidia and cystidioles absent; basidia clavate, with four sterigmata and a basal clamp connection, 10.5–14.5 × 3.5–4.5 μm; basidioles dominant, in shape similar to basidia, but slightly smaller.
Spores. Basidiospores ellipsoid, hyaline, thin-walled, smooth, IKI–, CB–, (1.7–)1.9– 2.5(–2.9) × (1.3–)1.5–2(–2.2) μm, L = 2.29 μm, W = 1.74 μm, Q = 1.33–1.81 (n = 120/4).
