Lyophyllum decastes…

tends to appear in open areas… roadsides, wood borders, and lawns. Appearance varies, which is why the “group” designation likely applies. The ones in this observation do look like Lepistas. But I think an occurrence of Lepista in Montana during April would be unlikely. I have found what I believe was L. decastes in early May.

I don’t know what it is but it has not the habitus of that species.For me this is not L.decastes.the texture should be almost gum-like, it is unusual to see those cracks on the caps.
I would have guessed Lepista of some sort but there is a lack of info,sorry.

I updated the spore print in the description it was very light cream or almost white. The mushroom was near a cottonwood tree and most of the lawn it was in was compacted and highly disturbed. I’m not sure if the gills are easily separated from the cap because the specimen is already dry.

did you do a spore print?

what color is it? what is the texture like?
are the gills easily separable from the cap flesh?
is it growing somewhat near to some tree? lawn alone is not the typical habitat for the species proposed.
