Beautiful small mushrooms on decaying wood. They have amazing prismatic spores. I surely though these were Mycena until I saw the rust colored spore print from white gills (!). I need help on this one.
Haven’t looked microscopically at anything but spores so far.
Spores “fill out” upon standing in Melzer’s for a few hours. The two photomicrographs are of the same slide, which I left on the microscope stage (light off/no heat) for a few hours. These spores are from the spore print, which was NOT dried with heat. Anyone ever see spores change like this?

It may be these spores were dehydrated and “collapsed” despite simple air drying of the spore print. I usually take my spore prints on glass or wax paper. I will look for such behavior in the future as well as compare fresh vs. dried spore prints and rehydrated spore appearances. I’ve never had the time or thought to do this.
Those are much more similar to the spores I saw from the mushrooms in my observation.
I’ve read about mushrooms swelling in KOH before but not Meltzer’s. Good careful work!
at what happened to the spores!!
and a good starting point for further research. I’ll look for microscopic features related to what you note in observation 74411. Thanks!
from the mushrooms in observation 74411, but that’s my best suggestion for a starting point.
In particular, the gills aren’t as decurrent, and the spores are much more stellate-diamond shaped than those of the mushroom in my observation.
Beautiful mushroom and amazing work!
