I only managed to save a small corner of the cap from the bugs and that got mixed in with some blewits and eaten.

It was also fruiting in close proximity to these observations:

64378 – http://mushroomobserver.org/64378?q=3rnV
64375 – http://mushroomobserver.org/64375?q=3rnV
64374 – http://mushroomobserver.org/64374?q=3rnV
And some Clitocybe nuda which are everywhere right now.

Lastly, thanks for the input from everyone.

I’ll bet that it’s an edible one, tho.

with a smooth whitish cap and double rings would not be my first guess on this one.
