No, I haven’t done cultivating.

Except for throwing saprobic scraps near the compost and lawn waste. And the morel crumbs and bolete tubes I scatter under my apple trees and blue spruce.

Reminiscent of Neolentinus lepidius

but not the same. I have never found anything as clearly P. dryinus as this one. Do you ever try cultivating?

Spores match Pleurotus.

I found some photos of P. dryinus spores online, and some showed the presence of oil drops, as do the ones seen here. No other Pleurotus mushroom looks like this. I haven’t seen this species in my area for many years. But, I do commonly see Neolentinus lepidius. So that species occurred to me momentarily. Actually, the spores for N. lepideus are similar to Pleurotus spores. But the mushrooms seen in this observation are clearly P. dryinus.

Thanks for the interest.

It does look like the P. dryinus at the farmers market

A lot of things on MO that don’t fit that description get labeled P. dryinus anyway. Either to have a real P. dryinus or you have a new species. It would be interesting to see if it can be cultivated – Michael Weese?

Thanks for the support…

on the dryinus proposal, Ryan. I hardly ever see this species in my area, let alone during early May. No spore drop, but I’ll see about teasing out some immature spores in a smash mount.
