Pleurotus ostreatus var “Black Pearl”- This is a relatively new variety of oyster which is a cross between an Asian and European Pleurotus ostreatus. In higher CO2 conditions the stems become meaty and thick like a king oyster (see images below); however, this variety is much easier to fruit than king oyster. See what phenotypes you get and share with us!

Black Pearl Oyster fruits best between 60-70°F but can fruit in the 50’s.

Interesting mushroom, great shipping and fast colonization!

Just got this wedge a couple weeks back and so excited to work on it. Already threw it in agar and was surprised with how fast it started colonizing. Can't wait to see the final result!
