The first micro-shot is of the gill edge at 400x in Meltzer’s. There are cheilocystidia, and they are lageniform with capitate ends. No pleurocystidia were obs.

The second micro-shot is of spores from the gills at 1000x in Meltzer’s. They are tan, lacrymose, warted and non-dextrinoid. Small spores, with an ave. size of 5 × 3 um.

The id of these is a little problematic. They are fairly well described in Bon and Roux “Le Genre Gymnopilus en Europe”, as G. josserandii. But this is a European name. There is in Hesler “North American Species of Gymnopilus”, G. subbellulus, with the small non-dextrinoid spores, and no veil. But this desc. includes the existence of plueorcystidia, which I didn’t see here. And the descriptions in the Bon and Roux are better anyway, so I am going with that id.
