Observation 45571: Parasola auricoma (Pat.) Redhead, Vilgalys & Hopple

When: 2010-05-15

Collection location: St. Genis, France [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Found in a grassy area, with some moss.

The first micro-shot is of the cap in radial section at 400x in KOH. Here you can see the cellular cap surface, with the globose elements. Large elongated pointed cystidia are missing, which are usually common in Coprinus-type species.

The second micro-shot is of spores from a gill at 1000x in KOH. The spores are ellipsoid, smooth, dark grey, with a more or less central germ pore.

This all points to P. auricoma pretty well. Two sources agreed on this.

Auricoma Parasol is easy to identify by their large esclerocistidios in the pileus. It seems strange that so striking structures do not appear in the microphotographs.
Parasol is a taxon described hemerobia Parasolid similar but without presenting sclerocistidios auricoma. I think these examples, the description better enter P. hemerobia.
