Your and Zaca’s observations (at least the first one)

are clearly different. Zaca’s second observation seems to be the same what I call conopilus. That they should be Parasola is confusing to me.
Never did someone make objections against the ID of those gregarious Psathyrellas with acute cap and slender stems.
I will if I can talk to them (and if I do not forget).

P. circellatipes

is described from France, but I’m not very familiar with it so maybe it can be readily distinguished in the field (?) and it should be noted that P. atrospora represents a species that is very common in my area, but after Smith described it in ‘72 from a single collection found in San Diego county, CA no one else seems to have bothered looking at it in detail (At least not enough to have tried Smith’s keys and post about it online)… I also think there is a good possibility its not the same as zaca’s obs 81014 or obs 82375. I have no idea of its full range, but it probably could grow in other places than CA if given the chance. Here are two of my observations to compare with, obs 64651 & obs 129851.

Also, Smith described species in the states that are supposed to look close without the setae on the cap, I don’t know if any such species occur in Europe.

Lastly, if you are able to talk to these experts, I would very much appreciate if you could add their thoughts to one of your relevent observations. :)

Thanks for the info.

Never heard of the other species to occur in Europe.
But then again you know lbm’s are not my faves.
I know mycologists from Czech and Austria that are very experts. I will ask them about these species when I am able to travel again.

Other species you could consider…

Even assuming this has the setae on the pileipellis there is still Psathyrella circellatipes which has been described from Europe (Although Smith claims its more common in the states) & I guess it would be nice to rule out P. atrospora which looks a lot like this, but described from California with larger spores than P. conopilus (I have some observations of that you can compare with). Also, Smith seemed to think P. conopilus doesn’t grow in large cespitose clusters like this while the others do, I’m not sure how true this is.

“3. Typically scattered to gregarious in groups of 2-3; pileus shining when moist. – 233. P. conopilea.
3. Densely cespitose (6-50 basidiocarps in a cluster). – 4
4. Spores 15-20(-21) X 7-9 X 8-10 /-‘. – 232. P. atrospora.
4. Spores smaller, 10-12 X 5-6.5 X 6.5-8 /-’. – P. circellatipes var. microspora
(12-15 X 6-8 /-” 234. P. circellatipes var. circellatipes)."
