Hygrocybe here, but the ones I’ve seen before are sticky/shiny, not shaggy/scaly like this one. Still haunting that log hoping it fruits again!

Many thanks Dave,

I will keep my eyes open in case it fruits again.

Best wishes

I have no solid suggestions for the species as applied to this mushroom. Jacob may be correct about this being Agaricus sulfureus. The cap looks like this species. But what little can be seen of the gills looks different than this species, ie. gills look sorta thick and well-separated. I think that for an unusual ID such as A. sulfureus in VA, more complete data is desirable before significant confidence applies. Too bad the squirrels got this before you did!

Okay… a long-shot, Tricholomopsis; something along the lines of T. rutilans. I’m not confident enough about this to propose it.

Thanks Dave, I was quite

surprised to see the distribution when I looked up the name A. sulfureus. Unfortunately that was the only specimen I could find, and I snapped a few shots with my phone then went back the next morning with my camera and sadly, it had been broken up by animal activity. I took some pictures of the remains in my hand. What a tiny little thing it was!
In the long-shot category, I have traveled to Southern China and Indonesia in recent years, including forested areas, so I suppose I could have unwittingly carried a spore home with me.
If not Agaricus, any ideas what else it might be?
Best wishes,

A. trisulphuratus…

would seem to be a very interesting find in Virginia. As per a quick online search of this name, I see reports only from Africa and Asia. Of course a saprobe like Agaricus can quickly become established in a new location.

The gills seen in this obs (5th photo down) don’t look like Agaricus gills to me.
