Material examined:— CHINA. Yunnan province: Kunming City (AEDZ市), Fangwang Tree Farm (Ẁffi林场), 25°38.24'N, 102°52.24'E, elev. 2262 m, 22 September 2011, Zhu-Liang Yang 5586 (KUN-HKAS 71071, GenBank Acc. No.: nrLSU = MW763011, ITS = MW762886).

Comments:—According to the previous description (He & Yang 2021), S. rugosiceps is the type species of the genus Spodocybe which is distinctive by its small basidiomata (pileus 0.5−2 cm diam.), grey-brown to grey-black finely tomentose pileus, elongate basidiospores (5–6 × 3–3.5 μm, Q = 1.55–1.95, Q m = 1.73 ± 0.14), 4-spored basidia, and growing in coniferous forests. The epithet “rugosiceps ” refers to its rugose pileus. Based on our field observation, the rugose pileus might be a valid character at only young period, however, this character is insignificant when mature. This species is known to occur in southwest China.
