Found on the base of a rotting live oak stump.
Kinda funny looking, but the id seems to be ok…
the first micro-shot is of the gill edge at 400x (my notes say KOH, but it looks like Meltzer’s there…). The cheilocystidia are cylidrical and inflated with blunt ends. No pleurocystidia were obs.
The second micro-shot is of the cap surface at 400x (again looks like Meltzer’s…). The surface is an epithelium, with no gelatin, no pileocystidia.
The third micro-shot is of spores from the stipe apex at 1000x in KOH (that is right this time). The spores are ellipsoid, smooth, with a clear germ pore and somewhat truncate, grey-brown. Ave spore size : length – 7.69 +/- 0.58 (err 0.16) um, width – 4.68 +/- 0.35 um (err: 0.10) – q : 1.65 +/- 0.13, on 15 spores.
Looking in the US and European sources, with the lack of pleurocystidia, and spores also agree well, these are really Psathyrella candolleana. They are kinda funny looking, compared to the normal obs. of these in grassy areas. But then mention how this is a rather variable species, with lots of variations stated in the past. This is just a less commonly id’ed variation from the woods, on rotting wood, not grass.
