Its Mycena Niveipes. Spores are amyloid, matches Hesler’s description very well. I’ll update some pictures of some microscopy that supports.

EDIT: and apparently it did smell like bleach… I would have said fabric softener, but it was bleach.

Spores look different, no bleach odor, stem was not “fragile,” flesh is “substantial.” Margin is inrolled, the cystidia look different, but maybe all these things are variable, I’m going to get some help in the lab today and will post if I get something difinitive.

Why not Mycena?

I see the genus was proposed, and this received an unfavorable vote. Check M. niveipes at Mushroom Expert… cap diameter up to 7 cm.

so does the unambiguously white spore print that was obtained

Definately NOT Pluteus either

rules out Pluteus.

not immature.

look at that thing.

got to be an immature Pluteus

but the sad hard facts are there is only one immature specimen, and it has had a long day and isn’t looking so good anymore, but I think I will see if I can sequence this one.

this is going to be fun.

Not Mycena

This thing is MEATY, I just put a dime next to it for a size reference while it is trying desperately to give me a spore print.
