Okay, thanks Django.

The stipe on these is fairly distinct from the fertile surface. Looking at foetidus photos, the fertile surface seems to transition more subtly into the stipe surface.

Only the second time that I found this (or it may have been foetidus). If I find this again, I’ll make a point to get a decent spore print, which seems to be the best way to distinguish (according to C du Q).

Found cinereus (possibly venosus) only once, in the Laurel Mountains of western PA (an awesome place to look for fungi).

C. foetidus is thicker, with less destinct ridges and a less distinct stem. C. venosus and C. cinereus var. multiplex are also similar, with C. venosus being the 2nd closest species to this IMO. I’ve found C. venosus before, which seems to be a bit darker than C. caeruleofuscus but I only have firsthand experience with C. venosus out of the 4 species mentioned.

Okay, just checked a few sources…

C. foetidus and C. caeruleofuscus (distinct taxa) look pretty similar to me. The main difference seems to be spore print color (not recorded for this observation). Also, it looks like foetidus is more likely to occur in fused clusters.

I see that you are fairly confident about C. caeruleofuscus being the correct ID, but quite confident that C foetidus is the incorrect ID. Is this a because of a new name? Or is it because these are simply not what is or had been called foetidus? Caeruleofuscus is a species name I have not seen until now.
