|Destructive Pholiota - Pholiota destruens|
It produces a cinnamon-brown spore print; you can sort of see the brownish stains of the spores on the gills in the above photo.
It's edible, but not one to seek out. The name, Destructive Pholiota, apparently comes from the fact that it quickly decays the wood it inhabits. It'll be interesting to watch this log and see if it indeed does seem to decay away more quickly (I'll report back in a few decades).
