I think your right Irene.

I didn’t take a spore print, but these tasted different than most oysters I’ve eaten, they tasted good, I don’t like oysters that much by themselves. I cooked some up to freeze to add to other mushroom dishes (filler) and these were much more appealing to my taste.

Pleurotus populinus?

Growing in early summer, on Populus, makes Pleurotus populinus, The Aspen Oyster, more likely. It has cream-coloured spores.

Pleurotus ostreatus grows mainly in winter, and the spores are some shade of lilac.
