Maybe I’m having an optical delusion

but the veil appears cottony or felty to me: not heavy. Not the double ring of Catathelasma, too thick even for most Tricholoma in my opinion. I’d tend to go with Stropharia, but haven’t seen many Stropharia with what appear to be universal veil remnants on the cap. Nor do I see any darkening of the gills when I enlarge the photos as big as possible. In my experience, Catathelasma is a huge mushrooms: specimens over a foot across are not that uncommon in my area. The other thing to seriously consider is that this was fruiting in June: totally non-typical in my area, and less likely in Montana, considering it could still be freezing almost every night there at this time. Interesting ’shroom. A poser.

Ditto Walt’s veil comment, also…

Just because anything COULD be in an urban area doesn’t mean that everything is equaly likely to be in an urban area: Stropharia – 90% found in a urban areas, Catathelasma – has anyone found one in a garden without nearby trees? Ever?

does not appear nearly as membranous or thick as Catathelasma.

I hope to go back on Friday

has a heavy veil and the habitat is artificial. Anything might have been carried along with a tree or other plant, or with woodchips or other material.

Meanwhile white, robust, tapering downward fits the general gestalt.

Anyway, a spore print will quickly give us new information if one is done; dark purple to black spores = Stropharia, white = Armillaria or allied.

Has a heavy veil and the habitat is wrong.

What about

An interesting one

Aspect resembles Tricholoma, Habitat does not. Spore color?
