That is really helpful. It looks about as easy to figure out as Afghanistan right now!

Yeah, the grey ones are tricky

Yeah, the grey Mycena are tricky, good luck with those. Actually with the scope and experience it is ok, but you need the scope. Plus a bunch of stuff when they are fresh. Let’s see here are some features to record: odor, marginate gills, viscid cap and or stipe, base of stipe bleeding fluid when cut, removable gelatin cuticle, gelatinized gill edge.

Then under the microscope you need: spores amyloid or not, cheilocystidia shape, gill trama dextrinoid or not, pleurocystidia or not, caulocystidia shape, pileus hyphae incrusted or not.

And then that might do it… along with the Smith mycena book, and Dr. Perry’s masters thesis on Mycena. Then it isn’t too bad.

Actually someone should do more of this, and get more obs. on the grey Mycenas, we mostly ignore them it seems…

This page should help to jump start you:
The Mycena key in Mushrooms Demystified is also a good place to read.

Could someone tell me what are some good characteristics to look for to help distinguish some of these grey brown abundant mycenas? Are there particular microscopic traits you should look for? Is it gill cystidia?
