Porphyrellus again

Debbie: Just to clarify the seldom clear generic shuffle of many boletes the genus Porphyrellus is not a “new” genus but goes back to 1931. So the boletes formerly known as Tylopilus porphyosporus (and a couple of possible synonyms) have been sent BACK to Porphyrellus (by some authors) to accomodate the un-tylopilus-like characters of rapid blue staining, a dark brown to blackish pore surface and an almost brown sporeprint.

OK, what is it again that has caused this former Tylopilus…

to be split into its own new genus? I think we may have had this discussion elsewhere, but I can’t seem to find it. help!
