probably stock obectives, i imagine. every seat in Dennis’ lab uses the same one.

these spores most certainly came from this collection. there is no mistaking that. an entire gill was sectioned and mounted. these were all along its face in the thousands.

Epispores, insofar as I’ve come to understand them, were not seen here. I can take another look on Monday though. Let me know if I should look for any other important characters.

The spores appear to be hyaline which makes it somewhat unlikely that they came from this collection. The universal veil remnants don’t look much like what I would expect to see in a universal veil. I have to admit I am not a universal veil expert as I have studied precisely 0 in the past.

What kind of microscope and objectives were you using for these micrographs?

It is a section Coprinopsis Narcotici. Almost certainly it Coprinopsis semitalis.
