Pleurotus

Last I heard, I think P. ostreatus and P. pulmonarius were for the most part indistinguishable (microscopically and macroscopically), but represented two biological species as they could not mate, one mostly being a “winter” oyster, the other mostly a “summer” oyster, but that their fruiting times overlapped as well.

Edit: these are also way too large for Pleurocybella, the largest one around 20cm.

is that they represent a species complex, with P. ostreatus one of these species. In some cases, knowing the exact type of wood is helpful.

Given the occurrence on hardwood and the robust stipes, I think we may rule out Pleurocybella.
