Yeah, I was going to suggest Agrocybe

After all other choices, it seems like Agrocybe was the only place to go here. Good there is an option that is so close and in the area at least. But to go to Agrocybe would take some more work really, to make sure of the cap surface structure and take a look at some cystidia. But with spores so close, and a known species in the area, this looks like a fairly good id.

is a very good idea, and the cap colour is within the variations too.

this looks to me like Agrocybe erebia. Spore shape appears to be a match as well.

And rusty brown spores mean?

I think that people need get over putting meaning in these slight differences in spore color, esp. in the brown spores. It was tried for years by people to create generic differences in slight changes in spore color, I just don’t think it pans out or helps. I’ve seen Psilocybe with “brown” spore prints, and Psathyrella for that matter. I’m not sure you can claim that much on “rusty” brown. (And I’ve seen may too many “brown” Galerina prints, and yellow-brown, and light brown… and…)

Looks like a rusty brown spore print. With the annulus and shape of spores it looks like a galerina of some sort. Psylisybe has a purple brown spore print.

Don’t look like Psilocybe…

Those do not look like Psilocybe spores… which should be thick walled, fat bottomed, with a germ pore. Then again they don’t look like Kuehneromyces spores either, which should be thin walled, ellipsoid with a germ pore. Also they look too smooth for a Galerina, and the thing doesn’t really look too much like a Galerina with that veil, and a non-striate cap…

That’s a weird one… where’s the germ pore on the spores, really looks like no germ pore…

Hopefully this collection will drop some spores. If not, I think there are a few on the annulus of the large specimen. I’ll get some spore shots up today.

Oooh… Psilocybe

Actually Psilocybe isn’t a bad idea either… There are more Psilocybes that do not stain blue, than ones that do. It just that no one really cares about those (poor, poor little Psilocybes, someone cares somewhere…). But that isn’t a bad idea really. All the ones I’ve seen of that kind though don’t have the membranous veil like these, more a fibrous veil that disappears.

I didn’t think these look much that Kuehneromyces really, until that last photo, where way down on the stipe, there is some scaling, so maybe. I would be nice to atleast get a spore shot, the shape of the spores would help put them to genus at least.

These were growing from the ground under mixed hardwoods. The largest cap is about 1 inch in diameter. At first I thought they were active psilocybes, but they do not bruise blue.

Any more info?

Any more info for these? Were they on wood or on the ground? Under trees, in grass? I can’t tell if the spores are brown or not here…
