Observation 50846: Parasola leiocephala (P.D. Orton) Redhead, Vilgalys & Hopple
When: 2010-08-13
Herbarium specimen reported

Notes: Found under mixed hardwoods, mostly oak and beech

Adding some micro-details:

The first micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are cylindrical to clavate. There are also many pleurocystidia, which are inflated clavate.

The second micro-shot is of the cap surface at 400x in KOH. The cap surface is a hymeniderm of globose elements, with no gelatin or pileocystidia.

The third micro-shot is of spored from the gill at 1000x in KOH. The spores are subglobose, and sub-angular, also flattened, dark grey, with a germ pore. The apr. size is 10 × 8 um (only 6 um in flattened aspect).

Putting this together with the thin smooth stipe, it seems that this best matches Parasola leiocephalus, at least according to Flora Agaracina Neerlandica vol. 6 (p35).
