Observation 14023: Conocybe rickeniana P.D. Orton
When: 2008-11-08
Collection location: St. Genis, France [Click for map]
No herbarium specimen

Notes: Found in grass near a wet area. Strange for a Galerina, these were found in grass and clover, but with no moss seen, or wood. If this holds up, this is one of the rare ones that grow on grass.

Updating obs., quite some time later… adding some micro-shots.

The first shot is the gill edge at 400x in Meltzer’s. Here the cheilocystidia can be seen and are lecythiform, as you would expect for Conocybe.

The second shot is the cap surface at 400x in Meltzer’s in radial section. Here the cap surface is hymeniform, again as expected for Conocybe.

The third shot is of the stipe surface near the apex at 400x in KOH. Here you can see the caulocystidia, which are also lecythiform, and large, with large capitulum 8-10um in diameter.

The forth shot is of spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, smooth, with a clear germ pore, apr. 8um long.

Putting this together, and looking in Flora Agaricina Neerlandica vol. 6, you get Conocybe rickeniana. These appeared to be Galerina at first, but that is clearly wrong, also the habitat in purely grass seemed wrong, but is a good habitat for Conocybe.
