Found under lodgepole pines, and mixed conifer, in mixed moss, mostly Polytrictum.

Part of the Yosemite National Park Fungal Survey, num. YNP1932.

Adding some micro-details:

The micro-shot is of the gill edge at 400x in Meltzer’s. The cheilocystidia are fusiod-ventricose, with blunt ends, on a non-fertile edge. Pleurocystidia were also obs., similar and numerous. The spores are dextrinoid, and come from 4-spored basidia.

The second micro-shot is of the cap surface at 400x in Meltzer’s. The surface is a cutis, without a gelatin layer. There are a few pileocystidia obs. here (they might be hard to see…), the pileocystidia are mostly similar to the cheilocystidia, but tend to be random, spread out and sparse.

The third micro-shot is of the stipe apex at 400x in KOH. The caulocystidia are fusiod-ventricose, and numerous, and were obs. at the apex and the base.

The fourth micro-shot is of spores from the stipe apex at 1000x in KOH. The spores are ellipsoid, pointed, roughened, and with a plage. The apr. size of the spores is 11.5 × 7 um.

Putting this together (and it almost needs all of this info), I get to Galerina perplexa. With some caveats, the spore size is too big here. In the European source Haan and Waylen (rip), the spore size is listed as 8-9 × 5-6 um. In Smith and Singer the north American source, it is listed as 8-11 × 5-6.5 um. This is closer to Smith and Singer, so we can go with it, it agrees in all other features, and does key out to the species in both sources.
