I have one but this specimen was not collected. I have used it, see here:

My scope does not have a reticule, so it is of little use for distinguishing between species when the important character is spore size.

I have not broken it out lately because there have been just so many cool mushrooms popping up this year. Time spent preparing slides and looking through the scope is time not spent in the woods hunting mushrooms.

psath delineata and rugocephala are almost identical in hand, and have undoubtedly both been eaten, one mistaken for the other. rugocephala is a known edible, delineata presumed (see above).

(Gee, I hope that Doug isn’t reading this!)

do you even have a scope, Dan? I can’t remember. But your macro shots are so nice I can’t image that your micro would compare! but it might nail a tricky ID…

Need microscope

According to Bill Roody, Ps. delineata and Ps. rugocephala are nearly identical and the differences are microscopic.

Psathyrella for sure, I just got the name wrong.

This is the corrugated Psathyrella. It is common on hardwood logs this time of year. The flesh is very brittle and watery.

Also might be Stropharia

Are you sure these are Psathyrella? It might be Stropharia? (Or might be Psathyrella…)

that’s either a highly unusual cap morph…

or another species entirely…
