Entoloma nidorosum
Description
Entoloma nidorosum has a convex cap, sometimes concave, 5-7 cm in diameter, occasionally with a faint bump in the center, silky, olive-gray, lightens when dried. The gills are whitish, then dirty pink. Spores are ellipsoidal, 8–10 × 7–8 μm. The stem is narrowly cylindrical, 5–9 × 0.2–0.8 cm, floury at the top, dense in the middle, later with a cavity, whitish. The pulp is whitish, with a strong ammonia odor.
Habitat in the pine-oak forest in October. In steppe cenoses it forms fruiting bodies from the end of May to the middle of June, therefore it belongs to the group of spring-early-summer species.
Common names: Nitrous Entoloma.
