Hello. Now we know the spore dimension, we can say that your images are C. insignis. The main character of this species is the spore ornamentation, but as seen in the microscopic image, that we wrong.

Thanks Alan, the spores seem a bit long for C. spelaiophila and I’m still not sure about the shape, what do you think? Uljé has them at “Spores [100,5,5] 7.8-11.7 × 6.4-8.2 × 5.3-7.2 µm”. Its supposed to be a “C. domesticus-like fungus”, knowing how the veil looks microscopically would of helped, oh well.

These spores don’t really strike me as like the spores of Coprinopsis spelaiophila seen here . And there is nothing about the zoned aspect of the foot in Uljé’s description or Flora Agaricina Neerlandica vol 6, where are you getting that from? :)

Alan, do you happen to have spore measurements somewhere?

Spelaiophilla.

This misclassified.

The zoned aspect of the foot and the spores are Coprinopsis spelaiophilla.
