Found under oak, beech.
The first micro-shot is of part of a gill edge at 400x in Meltzer’s. The cheilocystidia are mostly narrowly lageniform, most slightly fat and rounded on the base. Some cylidrical, some somewhat random. No pleurocystidia obs.
The second micro-shot is of spores from the gill at 1000x in Meltzer’s. The spores are ellipsoid, with a roughened surface, somewhat pointed, and strongly dextrinoid. The apr. ave. size is 10 × 6 um.
Putting this together, with the thicker rounded bottoms of the cystidia, and the strongly dextrinoid spores, this is Hebeloma sinapizans. Also the tan cap, and the scaly stipe.
This one I’ve put up as a comparison to a California obs. of a Hebeloma:
Just to show the difference with H. sinapizans. The obs. in California was clearly not H. crustiliniforme, but some might think it looks like H. sinapizans. But here it is clearly not the same under the microscope. Also even though the spores are brown to tan, there is clearly a difference when dextrinoid or not.
