What’s in a name? That which we call a Mousepee pinkgill
By any other name would still smell like mouse pee!
(with apologies to William Shakespeare)
Truth be known, I have no idea what mouse pee smells like (and these fungi had been rained on for several days so the smell may well have dissipated) but I’m fairly sure that is what these fungi are. The greenish stem is a bit of a giveaway, and these are definitely not Parrot waxcaps, which are the only other green-stemmed fungi I know (though that, in itself, doesn’t mean there aren’t others).
You can read up on the Mousepee pinkgill (Entoloma incanum) on the most excellent First Nature website here.
