I believe this is Galerina marginata. Location: Midwest USA
I see what looks like a remnant of a cortina on the one on the right which would mean it’s not Galerina marginata. The one on the left doesn’t have the strongest ring zone either.
Yes there appears to be remnants of a partial veil. I’m pretty sure Galerina marginata has a partial veil. I could be wrong tho, I’m definitely not qualified to ID them.
Let me help you feel a little more qualified, understanding different veil types and how they tear is a great way to level up you ID skills.
G. marginata has a fibrilose membranous partial veil which often leaves a persistent ring or a noticeable line on the stem.
The remnant in your photo looks like it came from a cobweb veil/cortina which is fleeting and doesn’t leave much of a mark on the stem.
Here’s a photo from Alan Rockefeller that shows some Galerina marginata with intact veils and veils that are beginning to tear.
The veils often wear off and don’t leave much of a remnant but they probably wouldn’t leave a single cobwebby strand like that with no color variation on either stem.
For comparison, here’s a Cortinarius sp. with a thick cortinate partial veil:
And here Hypholoma capnoides which is has a pseudo-cortinate veil somewhere in between a membranous veil and a cortina:
There are other species in Galerina and other genera with effervescent cobweb veils so this is a good clue you probably found one of those rather than G. marginata. Not that I blame you for not wanting to learn the subtleties between LBMs, mycologists didn’t want to either which is why they shoved them all in Galerina and why the genetic data is now telling us that Galerina needs to be split into something like five genera.
You could be right, but I still believe these are at least in the Galerina genus. My flash was a little harsh on the stems, so it’s hard to make out what’s left of the partial veil, but there is a clearly visible line.
These are a very close match and they’re listed as Galerina marginata
