With proper web access, was able to poke around. mushroomexpert.com has this species on hardwood with brick-red cap and non-greenish gills that matches well.

Thanks for mentioning H. capnoides, Debbie. As it is growing very clearly upon a huge red oak, it’s neither that species nor the eastern equivalent, N. radicosum (or is substrate less of a strict requirement than I think?).

However, that doesn’t answer your excellent point that it really doesn’t look livid enough to be H. fasciculare. I got a good purple-brown print, and a good view of the cortina on a young specimen, so there’s no question of it being Pholiota or some other superficially similar genus. Soon as we get an east-coast expert on here like Darvin, we can get all these pesky questions cleared up, eh? ;)
