Notes: Found under live oak, madrone, C. bay.
The first micro-shot is of the cap surface at 1000x in KOH. The surface hyphae are rather thin, and strongly encrusted. No clamp con. were obs.
The second micro-shot is of spores from the gill at 1000x in KOH. The spores are angular and 5-7 sided. The apr. ave. size is 10 × 8 um.
Also with this, the cystidia were uncertain. Only very few projecting cells on the edge, above the basidia, more or less cylidrical.
Putting this together, with the striate smooth cap, and the striate stipe, it seems to come out fairly well in the Largent keys as Nolanea papillata.
