Psathyrella spadicea was described from Europe, but is probably a cosmopolitan, and an example of a large and not very brittle Psathyrella.

I don’t know what this obs is – can’t even guess a species.

Is Psathyrella spadicea a west coast, USA species? I noticed the only two observation on here are from the west coast, I cannot find good info on.

The spores are more of a cinnamon red/rust/brown color, also note the cobwebby cortina on the lamellae, I found these at the base of a tree.

I was ruling out Cortinarius mainly because of the striate, cystidious stem, but also the deep purple spores.
I don’t know many Psathyrella species, but it reminds a bit of this (spadicea is one rather sturdy species that usually grows in small clusters near the stem base of trees): http://mushroomobserver.org/30018

I do have a scope, a rather old one, that can manage 1000x with oil immersion (which I use for measuring smaller details), but I get better pictures (sharper and better depth of field) at 400×. I’m no expert on this, so I can’t give any advice about microscopes or what you have in your market, but I beleive that it’s possible to get an acceptable new one for, say, 500 dollars..?

I did not think Psathyrella because of how large they were, how meaty the pilei and stipe were, also the spore print appeared to have a light cinnamon red/brown red hue to it.

I wish it was possible to get some micropics of the spores, am working on getting a scope.

Do you have a scope, if so what make/model would you recommend?

Is it possible
