P. populinus

Tentatively P. populinus seems to be the best current ID, based on fresh colour being so light and growth on aspen. Large spore size would help confirm to distinguish from P. ostreatus and P. pulmonarius (see mushroomexpert.com) but I don’t have a suitable scope available at the moment. This should be checked in the future if possible.

I added photos of the dried specimen, which has darkened considerably. This shows how important fresh photos are.

Thanks for the ideas, everyone. I didn’t realize how difficult this group was till now.

Thanks for the ideas. Don’t be shy – go ahead and propose the names (otherwise I will for you). I’ll have to look at this one again.

Pleurotus pulmonarius or Pleurotus populinus.
Looks too white for ostreatus IMO.
