Notes.
Hygrophorus fuscopapillatus, originally described from Sichuan, is distinguished by a combination of macro- and micro-morphological features. Its basidiomata are slender, with a pileus 2–7 cm diam. and a stipe measuring 5.5–10 × 0.4–1 cm. The pileus exhibits a greyish-brown disc and the lamellae are distant (25–35 full lamellae per pileus). A distinctive odour reminiscent of H. cossus (similar to the scent of goat moth larvae, Cossus cossus) is also characteristic. Microscopically, it produces ellipsoid basidiospores measuring 8–10 × 5–6 μm and the pileipellis is an ixotrichoderm, composed of subglobose, cylindrical or clavate elements that are insoluble in 5 % KOH. Ecologically, this species grows scattered in broadleaf forests, occasionally forming arcs or fairy rings and is likely associated with Quercus guyavaefolia. It is currently known only from the subalpine zone (2000–3500 m) of south-western China (Wang et al. 2020, 2023; this study).
