Description.

Pileus is 23.0– 32.2 mm in diameter, convex or broadly convex, occasionally umbonate on the disc, margin entire, occasionally straight; dry orhygrophanous, smooth, background gray or dark brown. Lamellae up to 3 mm broad, adnate or slightly sinuate, light brown, brown, getting dark near the pileus edge, eroded, veined. Stipe 72.4–80.2 × 3.2–3.8 mm, concolor with the pileus, paler toward base, cylindrical, equal, surface dry, smooth, silky, occasionally with the white fibrils or punctate near the pileus.

Basidiospores 8.6–11.6 × 8.1–9.8 μm [x ̄ = 9.6 ± 0.7 × 8.7 ± 0.4 μm, Q = 1.0–1.2, Q m = 1.1 ± 0.1, n = 20], subglobose-angular, asymmetrical, with 5–7 side. Basidia 40.7–47.9 × 11.2–13.2 μm, 4 - spored. Cheilocystidia absent. Pileipellis a cutis with a transition to a plagiotrichoderm and a trichoderm of cylindrical to slightly inflated hyphae 14.2–28.9 μm wide, with lightmembranous brown pigment. Clamp connections absent. Lamellae edge is fertile.

Notes.

Our samples clustered with samples from Northern America and Mongolia of E. fuligineocinereum in the phylogenetic tree (Fig. 1 View Figure 1 ). Morphologically, the morphological characteristics of our samples differs slightly from the previous descriptions. Basidiomes color of our samples is paler than those described in Largent (1971). In addition, our Chinese samples present slightly larger basidiospores compared with the holotype (7.5–9 × 7–8.5 μm, x ̄ = 8.3 × 7.7 μm, Largent 1971).
