Shows Pleurotus dryinus. Veil remnants on the cap are visible and the stipe is not as hairy.

that they are neither then. gill attachment looks better here for Hypsizygus. original Panus levis literature has the cap at 7-8cm, just as a note…

P. dryinus can get big but L. levis is generally larger in my experience.

Bessette/Fischer has dryinus at up to 12.5 cm and levis at 21 cm.

But L. levis always has the hairy stipe.

I think these 2 are something different.

Im confused why you mentioned size? Ive seen P dry as big as a baseball cap. The observation below looks like this one neither appearing to be p dry. I always see the veil on it as well as yellowing.
Agree the stipe is supposed to be hairy, according to the literature, the cap should be as well.
One thing that is different between the two that cant be seen here is the smell. That fishy/ classic oyster smell should be prominent.
