Velvet cap? Is it from a tricodermium, or does it have broom cells? You seen to suggest that is has no cystidia on the gills.

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.

but the amyloidity of the spores and other features showed this to be the extremely rare Dermoloma species; this is the first time I saw this too. The only “more frequent” species is D.cuneifolium: this I have seen thrice …
