Searching for an identification on the internet proved to be a bit difficult as none of the resources I normally used yielded a good fit for the characteristics of this one. I came upon this taxon that appeared to match quite well but there seems to be a lack of solid documentation on it. Help confirm?
Fruiting in moist lowlands with mixed hardwoods; mostly Salix. Spores elliptic, smooth, colorless, with single large oil inclusion, and
measured 17.5-21.25 x 11.25-13.75; a good match with H. solitaria (Abbott).
