Observation 10195: Conocybe velutipes (Velen.) Hauskn.
When: 2008-08-12
Herbarium specimen reported

Notes: Found at the edge of a grassy spot, with moss, near area with woody debris. I think these were mostly there for the moss.

9/6/2008 – Taking a look at these under the scope.

These first looked like Galerina, and there was moss near by, but quickly under the scope, and they are clearly not, but are Conocybes.

The first micro-shot is of a part of the cap surface at 400x in Meltzer’s. Here the surface is hymeniform, no gelatin layer, and no pileocystidia are observed.

The second micro-shot is of the stipe apex surface at 400x in KOH. There is a tight cluster of caulocystidia seen here, and the cystidia are either short and blunt, or filiform and long.

The third micro-shot is of spores on the stipe surface at 1000x in KOH. Here the spores are smooth, ellipsoid, brown, with a germ pore. The rough length of the spores is 12-14 microns.

Also in other looking there were 4-spored basidia seen.

Putting this together and going to the Flora Aragicina Neerlandica vol. 6 and the section on Conocybe, it agrees well with Conocybe velutipes. Which seems to be a common enough mushroom in Europe at the edge of lawns and grassy areas, which is where it was found here. It also describes the striations, the orange-brown patch in the cap center, but it says these should have thin long pileocystidia, which I didn’t see. The caps looked a little old and somewhat beatup, so those might have been lost.
