Firm, white, no gills

[flipjargendy]

This mushroom is in Montana, near a pond, in grass. It is very firm, like a Bolete. There were no gills, it felt like pours. The underside of the cap was concave, not flat.

I've done some looking and am just not finding an ID. If you can point me in the right direction, that would be great.

Did you pick it and look at the underside?

It sounds like you just felt it. It is easy to think there are no gills just by feel alone, if they are still covered by a veil. Also if they are extremely crowded together

That is a good pont about just feeling. Did not pick it up. I tried to get the camera under it but it was a worthless effort. Maybe I'll just pick it if I get over there again.

I’ve seen caps that look similar with multiple slugs chomping at their bits

To me it looks like a mushroom infected with a white mold.
