Description: Original observation #4747601 (iNaturalist)
Occurrence Remarks:

Under mixed pine and hardwood. No odor. Cap not viscid.

In the field I thought the spores were dark purple brown, but now that they are dried and I am looking at them closely in the sunlight, they look more like a medium chocolate brown.

Cheilocystidia and pleurocystidia abundant and very similar. Most of the cystidia are hyaline, however some have a bright yellow color in both water and KOH. Basidia 2 and 4 spored, and very small compared to the cystidia.

Spores slightly inequilateral, ellipsoid in face view and mango shaped in side view. Hilar appendage is conspicuous. No germ pore can be seen.
