Lamellae adnatae, secedentes, confertae, aridae, acie subtilissime crenulatae, ex albido-argillaceo dilute ferrugineae, 2 mm. latae. Sporae ovoideo-oblongatae, eguttulatae aut primitus uniguttulatae, laeves, longit. 6-10 mmm., crassit. 4-6 mmm. Inter folia in abiegno prope lacum Salois par. Tammela, m. Aug. 1883.

English translation: Pileus fleshy, plano-convex, circular, blunt, glabrous, smooth, dry, pale yellowish, more saturated when dry, up to 3 cm broad. Stipe solid then hollow, elongate, equal, for most of the length flexuous, adpressed fibrillose, at apex slightly pruinose, pallescent, towards base umber brown, particularly when handled, 2–3 cm high, 3–4 mm thick. Lamellae adnate, free, crowded, dry, edge subtly crenulate, white then clay-coloured to diluted reddish brown, 2 mm broad. Spores ovoid-oblong, also when young without guttules, smooth, 6–10 μm long, 4–6 μm thick. Among leaves in a fir woodland near the lake Saloid in Tammela Parish, Aug. 1883. Growing in groups. Taste bitter. Odour strong, like soap (saponaceus). Close to H. elatus (Batsch) but differing in odour and taste, and the not twisted stipe, and small size.

Commentary: We have examined the neotype material morphologically and molecularly and confirmed this is: = Hebeloma syrjense P. Karst.
