Observation 23299: Cystoderma Fayod

Found a few scattered in trail along lakeshore. Sub-rainforest interior cedar-hemlock (“ICH”) zone. Spore print failed, but spores appear to be whitish at 30×.

Update: spores smooth, elliptical, clear, ~4.5 × 2.5 µm; no pileo-, pleuro- or cheilocystidia; pileipellis is a… I guess that’s an epithelium: thick layer of vertical chains of inflated cells stained reddish-brown (on drying it cracks up into a bunch of wart-like areoles.

I’m all about funky cystidia, but alas, no dice.

Check for cystidia

If you think this might be C. cinnabarina, it is an easy id, check for cystidia on the gill edge. It is the only Cystoderma/Cystodermella with cystidia, and they are large and funky, long, spear shaped, with incrustations.
