Found by Noah Siegel.

Looking at this under scope, I get the species of Crepidotus applanatus var. applanatus.

The first micro-shot is of the cap surface in radial section in Meltzer’s at 400×. This shows a cutis of compressed fibrals, with no gelatin or pileocystidia.

The second micro-shot is of the gill edge in Meltzer’s at 400×. This shows the clavate cheilocystidia. No pleurocystidia were observed.

The third micro-shot shows the spores in Meltzer’s at 1000×. Here the spores show no reaction to the reagent, they are globose with spines and about 5um in size.

Putting this together makes this Crepidotus applanatus var. applanatus.
