Observation 50629: Pluteus chrysophaeus (Schaeff.) Quél.
When: 2010-08-09
Herbarium specimen reported

Notes: Under mixed hardwood forests, mostly oak and beech. On a large very rotten log.

Adding some micro-details:

The first micro-shot is of the cap surface at 400x in KOH. The surface is hymeniform, with lightly pigmented even elements.

The second micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are thin-walled and clavate. There is also lots of similar pleurocystidia, although are quite a few are thinner.

The third micro-shot is of spores from the gill at 1000x in KOH. The spores are sub-globose, smooth, without a germ pore. The apr. size is 6 × 5 um.

With the yellow colors and the hymeniform surface, this is Pluteus chrysophaeus.

pileipellis structure

I would like to see the type of pileipellis this collection has. I somehow don’t think they have a ‘hispidoderm’ as Pluteus leoninus should have (that is a pileipellis made up of long upright elements).
If it is a celluloderm, made up of clavate to sphaeropedunculate cells, then it is one of the species in the Pluteus chrysophaeus group.
