Phylloporus taxonomy

Have the types of foliiporus and leucomycelinus been sequenced? Are the species epithets anchored conclusively? The 2-3 recent papers of Phylloporus phylogeny with substantial species sampling — and those are already 7-9 years old — lack those data, so my understanding the answer is no. The last of these papers (on global Phylloporus, but with a clear focus on Asian taxa) by Zeng et al. (2013) suggests rhodoxanthus and leucomycelinus are species groups. This publication is available online for free (including a downloadable pdf) at

Thanks for the info on sequencing in Florida. The guides i used did not have phylloporus foliiporous. I see now that mushroom expert has a good breakdown on region and charateristics.

I agree with Igor… The two white mycelium, blue staining Phylloporus that are commonly found in this area are P. foliiporus and P. leucomycelinus. The problem is that the original description of foliiporus says it is supposed to have yellow mycelium. Sequences from Florida with white mycelium are blast matching to foliiporus.
