Of the four names I believe have seemingly been applied to this entity…

turpis, necator, plumbeus, sordidus, only sordidus was authored by a North American, Peck. I surmise that NA and European material has been shown to represent the same species (via DNA, otherwise Peck’s name would seem to apply). If so, then this appears to lend credibility to the hypothesis that eastern NA and western NA material represent the same species (a seemingly unusual situation for a mycorrhizal fungus, but in this case perhaps all are “imports”).

So, does this boil down to a debate over which name applies to Euro material? Or perhaps there are more than one Euro species of this dirty-green/brown scrobiculate Lactarius…?

Lactarius necator (Bull.) Pers. should be the Curent Name:

Noordeloos, Machiel E., and Thomas W. Kuyper. 1999. “Notulae ad Floram agaricinam neerlandicam—XXXV. On the typification of Lactarius necator.” Persoonia-Molecular Phylogeny and Evolution of Fungi 17( no.2): 291-294.

I don’t know if their conclusion to dump the name Lactarius turpis is correct after the recent ICN removed the starting point for fungi, but the authors concluded that their paper makes clear that the name L. necator can be maintained and points out that the name L. plumbeus
should not be used for that taxon.

I doubt that this fungus reallycares, how it is called.
P.S. In this Name Page I undeprecated the deprecated name Lactarius necator and, in compliance of the MO System Of Naming, I would call it a Preferred Synonym. By the way, in Species Fungorum the Preferred Synonyms are called Current Names. I think that the term “Preferred Synonym” should be deprecated from MO as well.
