this is a pretty shaggy Paxillus to be an involutus…

…which is mostly described as having a cap that is finely hairy or downy, wearing to smooth. The gills don’t seem to be forked/forming pores where they meet the stipe. I agree that it is probably a Pax, tho…you should easily be able to peel the gills (like a boletus) if indeed it is a Paxillus. Involutus also should stain brown in all parts…I vote Paxillus species.

saprobic on hemlock

The area was populated almost exclusively by hemlock and birch. This mushroom was growing from an old log that was almost certainly hemlock. It does look a bit like Lactarius but it was tougher and more pliable than one would expect from that genus. I don’t recall seeing any latex, but I did not even think to check.

little Paxillus. It isn’t automatically a Tapinella if it happens to grow on wood, is it?

Trees near by?

What trees were near by here? Did you check for latex on the gills. It looks like one of the shaggy edged Lactarius, and I think those have species specific relationships with certain trees.
