Found under oak, hornbeam, fir.
Adding some micro-details.
The first micro-shot is of the cap surface at 400x in KOH. The cap surface is a hymeniderm, with random elements. This shot shows how a number of the elements have long thin projections.
The second micro-shot is of the cap surface at 400x in KOH. Again showing the random elements, from clavate, to lageniform, to globose.
The third micro-shot is of the gill edge at 400x in KOH. The gill edges were rather poor, and beat up, this is a small section that folded over, but showed the cheilocystidia best. The cystidia are lageniform with narrow projections with nodules and pointed ends. Pleurocystidia were uncertain in this one given the poor state of the gills.
The fourth micro-shot is of spores from the gill edge at 1000x in KOH. The spores are sub-globose, smooth without a germ pore. The apr. size of the spores are 7 × 6 um.
With the random surface elements, and the narrow projections on the cystidia, this is Pluteus thomsonii. Although this is a really old and poor specimen. I just am able here to get bragging rights, put a point on the map of where this species could be found.
