Sarcoporia yunnanensis 

Sarcoporia yunnanensis Y. Yang and C.L. Zhao

MycoBank number: 851228.

Basidiomata Annual, pileate, corky when fresh, brittle and hard when dry, odorless, and up to 4 cm long, 3 cm wide, and 1.5 cm thick. Pileal surface salmon to reddish-brown; margin cream, obtuse. Pore surface orange-yellow, pores angular, 2–4 per mm; context orange-brown, cottony, up to 1 cm thick; tubes pinkish-buff, up to 5 mm, extremely brittle and shattering easily when dry. Hyphal system Monomitic; generative hyphae with clamp connections, colorless, IKI–, CB–, tissues unchanged in KOH. Generative hyphae in the tube infrequent, colorless, thin-walled, easily collapsing, 1.5–3.5 µm in diameter. Generative hyphae in the context infrequent, colorless, thin-walled, 3–5 µm in diameter. Hymenium Cystidia and cystidoles absent; basidia clavate, with four short sterigmata and a basal clamp connection, 15.5–22.5 × 4–6 µm; basidioles in shape similar to basidia, but slightly smaller. Basidiospores ellipsoid, colorless, thick-walled, smooth, dextrinoid, weakly cyanophilous, 4–5.5(–6) × 2.5–4(–4.5) µm, L = 4.84 µm, W = 3.31 µm, Q = 1.48 (n = 30/1).

Fig. 1 Maximum parsimony strict consensus tree illustrating the phylogeny of three new species and related species in Polyporales based on ITS + nLSU + mt-SSU + TEF1 + RPB1 + RPB2 sequences. Branches are labeled with maximum likelihood bootstrap values ≥ 70%, parsimony bootstrap values ≥ 50%, and Bayesian posterior probabilities ≥ 0.95. The new species are in bold.
