Description.

Pileus 29–33.4 mm in diameter, campanulate, occasionally with a broad umbo, disc depressed or deeply indented, margin entire, straight, slightly uplifted; surfacedry, background gray or light brown, covered with brown fibrillose scales in triangular shape, scales denser and darker at the disc. Lamellae up to 4 mm broad, adnate to decurrent, subdistant, white, light pink, entire, veined. Stipe 48.1–59.6 × 2.3–2.5 cm, light brown, concolor with the pileus, surface dry, smooth, base white with hypha.

Basidiospores 9.3–12.0 × 6.7–9.2 μm [x ̄ = 10.7 ± 0.7 × 8.1 ± 0.6 μm, Q = 1.2–1.6, Q m = 1.3 ± 0.1, n = 20], heterodiametric, with 5–7 angles in side-view. Basidia 28.5–38.6 × 9.8–13.6 μm, 4 - spored. Cheilocystidia basidia-like, 13.2–19.8 × 3.7–7.4 μm. Pileipellis a cutis with a transition to a plagiotrichoderm and a trichoderm of cylindrical to slightly inflated hyphae 8.2–17.9 μm wide, hyaline, membranous light brown. Clamp connections absent. Lamellae edge is heterogeneous.

Notes.

A sample from Qilian Mountain clustered two European samples of E. glaucobasis in the phylogenetic tree (Fig. 1 View Figure 1 ). This species is originally described from Germany. Our sample generally coincides with the original description of E. glaucobasis . Difference is that the cheilocystidia is basidia-like in our sample while is clavate or vesicular according to the original description ( Noordeloos 1985).
