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.

Excellent Culture

This was my first time ordering any sort of mushroom culture and I don't think I will go anywhere else. I ordered this along with a few other strains of gourmet mushrooms. 2 weeks after inoculation I am already seeing a substantial amount of mycelium and looks like it may be ready for fruiting in another couple of weeks. Order came very discreet and was shipped out promptly. I even received 2 free syringes of culture with my order!

Loved Everything!

Great product and excellent service! Loved the freebie! The cash by mail worked perfectly well.
