: referring to the locality (
Yunnan Province
) of the
type
specimen.
Description:—
Basidiocarps
annual, gregarious, without odor or taste and corky when fresh, becoming hard corky upon drying.
Pilei
spathulate to flabelliform, more or less stipitate, projecting up to
2 cm
wide,
1 cm
thick at centre. Pileal surface slightly tomentose, zonate, buff to ochraceous when fresh and ochraceous to pale brown upon drying.
Hymenophore surface
smooth, cream to buff when fresh, turn to buff to pale brown upon drying.
Hyphal structure
dimitic; generative hyphae with clamps, thin- to thick-walled, unbranched, 2.5–3.5 μm in diam.; skeletal hyphae colorless, thick-walled with a wide to narrow lumen, unbranched, 3–4.5 μm in diam.; IKI–,
CB
–, tissues unchanged in KOH.
Hymenium
:—Cystidia (caulocystidia) cylindrical with an apex or not, present in subiculum, thin- to thick-walled, 30–55 × 3–5 μm, cystidioles absent;
basidia
narrowly clavate to subcylindrical, with 4(2) sterigmata and a basal clamp, 25–32 × 2.5–4 μm; basidioles dominant, in shape similar to basidia, but slightly smaller.
Basidiospores
ellipsoid to subglobose, hyaline, thin-walled, smooth, IKI–,
CB
–, 3–3.5(–4) × 2.5–3(–3.5) μm, L = 3.34 μm, W = 2.71 μm, Q =1.2–1.31 (n = 120/4).
