Scroll down the comments, they are the cells that resemble turkey legs.

more micro?

I can take a bunch more spore pics, and measure them… For sulphidia, am I just looking for distinct yellowish cystidia?

Spore color?

Can you try to photograph more spores and describe the ornamentation better? Stuff like if the germ pore is oblique in the side view or not (Can be a very subtle characteristic) and spore size can help a lot. There is nothing about the cheilocystidia that indicates Panaeolus over Panaeolina, but the blackish gills and seemingly smooth spores seem to point towards Panaeolus. The broad cheilocystidia would be consistent with P. cinctulus, but I wouldn’t vote strongly on that name without more details. Are there any sulphidia?

Thanks

For adding a picture of the specimen, pulk. I can see now why you were insistent about Panaeolina. the spores are smooth though, right?

Psathyrella was just a suggestion

Panaeolina have very verrucose spores. If the spores are smooth then Panaeolus is likely.

Psathyrella?

I’d like to believe I can say it’s 100% not Psathyrella. I just picked up some Panaeolina/us in the grass on the way while walking to the lab…

I’ll try to remember to note the make/model next time I go in.

make and model microscope are you using?
