Observation 187772: Pyrenopsis (Nyl.) Nyl.
When: 2014-11-08

Notes: Another lichen from the same place on Gold Creek trail growing on or with Andreaea (see http://mushroomobserver.org/187473?q=2Kdwc and https://www.flickr.com/photos/29750062@N06/15508584428/) This one needs more work, but my specimen is small and may be someone (Jason?) can save me from floundering around. If not I’ll try working on it a bit more. Just wanted to get it up.

I know almost nothing about cyanobacterial crusts :(

I’m also away from my library. Not that I’d have any better opinion about your alleged Gleocapsa, anyway…
