Mycelium

That’s what I thought, judging from the white dusting on the lower stipe…

The history of foliiporus is complex and confusing. Originally described by Murrill in 1943 as Gomphidius foliiporus,1 it was re-described in 1945 in exquisite detail by Singer as a subspecies of P. rhodoxanthus.2 A comparison of these two early descriptions can be attempted if you follow the links in the reference section below and have enough patience to read them. The key points are that the flesh is supposed to blue, and the basal mycelium is “yellowish white or rich yellow” (Singer). Singer raised foliiporus to the species level in 1978. A NA collection identified as P. foliiporus was shown not to be closely related to P. rhodoxanthus and was instead a very close relative of P. rubiginosus from SE Asia in Zeng et al. (2012).3

I think that the basal mycelium is white.

Was it white or yellow?
