features
The species forms fruit bodies divided into hat and stem, the hat is 0.8-2.5 cm wide, it is frustoconical to bell-shaped, often with a pointed hump. When moist it is dark yellow-brown and fades to pale yellowish-brown or greyish-brown as it dries. The surface is smooth and covered by a thin gelatinous skin that can hardly or not at all be removed. Sticky when wet. The lamellae are grown or attached at the base, they are close to not close together and are narrow to moderately wide. They are dull greyish brown to cinnamon brown and when ripe they are smoky brown in color, the lamellar edges remain whitish. The stem becomes 2–8 cm long and 1–3 mm thick. It is equally thick everywhere, only a little wider at the base, brittle, brittle, hollow and slightly bent. Beneath a whitish, fibrous coating, it is dirty white to brownish in color. A velum partiale is barely developed, veil-like, very thin, often barely recognizable and soon disappears. The spore powder is dark purple-brown, the spores are 6–9.5 × 4.5–5.5 µm in size. The species has four-pore basidia , more rarely two -pore ones are sometimes present. There are no pleurocystids . The spindle-like, bulbous to bottle-shaped cheilocystids are 24–40 µm long and 4.4–7 (8.8) µm wide, and have a long, winding neck 1.6–2.2 µm thick.
