Cantharellus versicolor S. C. Shao & P. G. Liu , sp. nov. Fig. 1.

MycoBank no.: MB 810623;

Etymology: the species epithet refers to the darkening characteristic of upon injury.

Holotype: CHINA. Yunnan Prov.: elev. 3294 m, Diqing Tibetan Autonomous Prefecture, Shangri-La county, 23 July 2007., X.F. Tian 161 ( HKAS 55762 ).

Basidiomata extremely fleshy and compact, medium-sized, 60−100 mm in height. Pileus small, 20−30 mm in diam., sandy brown (5C4−5C5) to dark brown (5B8−5C8), firstly applanate with involute margin, becoming more or less plane with age; surface entirely covered with dark brown (5F4) scales, often developing gray after handling. Context solid, fleshy, off-white to pale yellow (1A2), 5−7 mm thick at mid-radius, turning dark brown (5E8) when handled or upon injury.

Odor mild, fungic. Subhymenium shortly decurrent, composed of relatively few and shallow veins, rarely forking and anastomosing, yellow to orange yellow (3A4−4A5). Stipe solid, subcylindrical, 60−100 × 8−10 mm, concolorous or slightly paler than the subhymenium, turning gray after injury. Basidiospores print not obtained.

Basidiospores oval to ellipsoid, smooth, colorless and hyaline, thin-walled, (8.5−) 9.0−10.0 × 5.0−6.0 μm,Q= (1.47−) 1.50−1.78, Q m = 1.65±0.1. Basidia narrowly clavulate to subcylindrical, mostly 83−103 × 7−12 μm, with (2−) 4 (−5) sterigmata. Cystidia absent. Pileipellis composed of two types of hyphae, with irregular, erected, thickwalled hyphae in the scales and thin-walled interwoven hyphae away from the squamules; both composed of similar, subcylindrical hyphae, measuring 5.5−14.0 μm diam., with pale yellow tint. Subhymenium trama composed of filamentous hyphae 3.0−8.0 μm diam., colorless, thin-walled; clamp connections in all tissues.

Habit, habitat and distribution: caespitose, under trees of Abies fabri (Mast.) Craib. ( Pinaceae ) forest.
