Not sure, with the cedar odor you could be looking at a Hygrophorus. But it also could be Clitocybe. But the with the free gills, neither of those really fit. Then you get into the Collybia/Gymnopus area, which these more have the look of, but all these small, thin, white spored, but not Mycena stuff just confuses me. (But, like the Mycena stuff doesn’t confuse me… but at least you can usually say, ah, Mycena there.)
It would nice to compare to Denise Gregory’s thesis, but I’m not sure you can get a copy of this yet…
One thing, I kinda have a need for interesting stuff to put under the microscope in the mycology class. I could use the dried material here, and put it under the scope, and see what microscopic details come up. Probably still won’t get any better, but I could add some microscopic details to the observation…
