The North American Species of Pholiota

has a specimen from Ohio listed under “specimens examined”. It’s probably just less common here since we only have one common poplar species (cottonwood), which would limit it to growing along creeks and rivers large enough and powerful enough to have cottonwoods, tulip trees, etc. and not succeed to beech-maple. The type specimen is from Europe, so eastern H. populnea is more likely to be the real thing than the western form. I’ve some other uncommon species (Pholiota multifolia) and a new record for Ohio at this park (Panaeolus bisporus).

Pholiota destruens

is an old name, now put in synonymy. I saw it once in Ontario
Observation 67413: Pholiota destruens var. edmundii A.H. Sm. & Hesler.

Based on the photos I have seen of Western H. populnea, I have my doubts that they are the same. I will propose H. populnea as a could be on that observation. It does have some resemblance to your find. Whatever the name, it is an uncommon species in Ohio.

map it doesn’t seem to be common anywhere other than the PNW. It does seem to be a more northern species though. Are there Pholiota species or Hemipholiota species that look similar to Hemipholiota populnea and occur in the same region? I have a copy of The North American Species of Pholiota and I’ll scope it and key it out there at some point.

If this is H. populnea, this is a rare Ohio record.
