It makes me more confident of the ID. So much so that I’m not sorry that I disposed of the specimen without doing more ’scoping.

Kees Uljé said, “Coprinus niveus can be easily recognized by the very large spores which are limoniform in frontal view and ellipsoid in side-view, borne on 4-spored basidia.” The spores look right, how about the basidia?
