Whatever you prefer to call this “subtropical species” it has been common at the NEMF foray in recent years. In the earlier years of this foray it was never found. Global warming or whatever the reason, it is moving north. It was in Ohio in the 80’s when I discussed it with Wm. B. Cooke who verified the identification.

Thanks Parker.

Sounds like the name for this type mushroom is currently being sorted out, hence your genus-level proposal. I’ll adjust my proposals.

This type polypore certainly is very common here in Pennsylvania. Intact fruit bodies persist through the winter.

MO has L. elegans as the prefered name, but according to “Tropical Trametes lactinea is widely distributed in the eastern USA” T. elegans makes more sense.

“Trametes elegans is often regarded a member of
genus Lenzites (L. elegans (Spreng.) Pat.) based on its sometimes lamellate
hymenophore and some pointed ends of binding hyphae protruding into
hymenium, reminiscent of the catahymenium characteristic of L. betulinus
(L.) Fr. (Nuñez & Ryvarden 2001). Nevertheless, our ITS region sequence
phylogram shows no similarity between T. elegans and L. betulina, and so we
find the name T. elegans more appropriate.”

And according to “Trametes gibbosa (Basidiomycetes, Polyporales) in the USA and Canada” it’s unlikely that T. elegans occurs in the northern states or Canada.

“Lenzites elegans is primarily a tropical species that can
also be found in the southernmost states of the USA, and in
the Mississippi basin. The occurrence of this species in the
northern states and Canada is very unlikely, as indicated by
Overholts (1953), and the senior author was unable to find a
single specimen during his multiple visits to the east coast
that included many localities from the Great Smoky Mountains
in the south, to the Adirondack Park in New York
State. Trametes gibbosa, on the other hand, was quite frequent,
at least in Pennsylvania.”

I mostly suck at polypores.
