Which granulatus is the underside “spot on”? I doubt this is the European mushroom that you proposed.

The underside is spot on for S. granulatus. The cap looks bleached out but the typical mottling is visible. Also it is probable that white pine was the host.

I see 5-needle clusters (some needles broken off ), so most likely P. strobus , which would make it the NA “granulatus”.

Walt, it looks like this was with hard pine rather than soft pine

which I think is the reason for your name proposal. So are you thinking it was introduced?
