Black Pearl Oyster Agar Wedge

Description

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.

Fruited from 50-60°F in modified monotub with King Oyster thick stem phenotype.

Same block as above but second flush, also fruited from 50-60°F in modified monotub with more of a canonical Oyster cluster phenotype.
