Getting back to this one, to use as a comparison to other Camarophyllus species, and adding some micro-shots.
The first micro-shot is of a gill section, at 100x in KOH. Here it can clearly be seen the interwoven lamellar trama between the rows of basidia, so clearly a Camarophyllus species. The next micro-shot is of a very thin gill section at 400x in KOH. And here you can see the elongated basidia of Hygrophorus species, a row of connective cells, and again the interwoven trama, this shot doesn’t really point out anything for the id, but I thought it was a pretty good looking section. The third micro-shot is of tissue from the upper stipe surface, to look for mature spore sizes. Unfortunately I couldn’t find a spot with lots of spores in focus at once, so only two spore here. This is at 1000x in KOH, and I still can’t quite get 1000x in focus in camera yet.
But here the spores have on oil drop in them, and are elliptical.
The ave spore sizes are : 7.06 × 5.77 microns – q : 1.23, on 7 spores. But I haven’t really calibrated the scope’s reticule yet, and I think this might be high.
Anyway, here is a baseline for a well known Camarophyllus species. One thing I learned with inamyloid, non-dextrinoid, hyline stuff, don’t just use KOH… next time on Hygrophorus, use the Congo Red first…

I have also seen both skinny and fat versions, but the skinny was unusual enough to me at the time that I illustrated the difference. I will photograph it and post it.
Small, slender specimens are the norm, or were until this season, at the park (Howarth)where I frequently find C. pratensis.
Otherwise it looks right colorwise…D.
Was it growing in deep duff? I’m used to this species been more stout.
