Observation 4259: Bolbitius lacteus J.E. Lange
When: 2007-08-04
No herbarium specimen

Notes: ID from Arora again. Small, fragile, pleated, viscid cap, and cinnamon brown spore print convince me it is Bolbitius. The color is rather variable; usually whitish to brownish but occasionally I see one that is quite yellowish. All were from the same section of lawn nearby, fruiting regularly for several weeks in August. (Sharing lawn with Coprinus disseminatus and Panaeolus foenisecii.) Arora suggests either B. vitellinus (if yellow) and B. lacteus (if whitish). Photos on the web make it clear that the yellow coloration of B. vitellinus is obvious, so I’m tentatively calling it B. lacteus. Is it possible both species are present? More notes here.

I’ve changed this to from B. lacteus to B. coprophilus on Nathan’s suggestion. (The key and descriptions in Flora Agaricina Neerlandica make it clear it is not the former.)

obs 103649, I wonder how they compare to the European taxon genetically. The European key obviously has far fewer names than there are Bolbitius….

Bolbitius coprophilus is also possible
