73776, showed no blue or blue/green at the stipe base. Also, the spines that run down the stipe seen in the collection posted here (74093) are not as long and do not go as far down the stipe as in 73776. Irene’s comment suggests that this subtlety may be significant. So I think you are correct, Hamilton. The collections possibly represent different types/species.

seems to have been applied on several different taxa in NA. The ones I can’t agree with, are the greyish brown ones with long decurrent spines.

The real scabrosus is typically pinkish and furry when young, turning reddish brown and soon scaly. The spines are decurrent (sort of), but downwards they are quickly reduced to small warts.

also grows with oaks according to: http://mushroomobserver.org/name/show_name_description/698 and other literature. This seems to fit it pretty well.

Irene, the taste is bitter and the stem base is bluish-green. No conifers near these for some distance. I’ve found these in large numbers under oak.

Dave, they look similar to your obs. but different in my opinion. I tend to make mountains out of mole hills though, so who knows. I’ll have to make a collection of these.

Similar to my hardwood habitat collection, the spines on Ham’s spceimens run down the stipe.

and bitter taste?
It looks like what we call Sarcodon scabrosus in Scandinavia, but they grow typically with pine. Possibly another species in that group that grows with hardwoods.
