but spores are oblong ellipsoid and about 6-8×3,5-5µm and strongly amyloid, clamp connections present.Most basidias have four spores.
Macroscopical distinctive feature is hygrophanous velvety cap, thickened gills that have a greyish-brown tinge and a stipe which is finely pruinose-flocculose at the apex. Context is odorless or faintly mealy.It grows in natural meadows on calcareous soil, mostly in late fall.
