Herbarium specimen reported

The first micro-shot is of the cap surface at 400x in KOH. The cap surface is hymeniform, in single layer of more of less globose elements, with intercellular pigments.

The second micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are thin walled, mostly lageniform, some clavate, with blunt ends, some with thick encrustations. Pleurocystidia were also obs.

The third micro-shot is of spores from gill at 1000x in KOH. The spores are sub-globose, smooth, the apr. ave. size is 6.5 × 5.5 um.

The micro details agree with a few Pluteus, but with the crome-yellow stipe, this is Pluteus romellii.
