King Blue Oyster Mushroom
Pleurotus ostreatus
10 cc/mL liquid culture
King Blue is a commercially used name for a blue toned form of Pleurotus ostreatus. Unlike Pleurotus columbinus, which is recognized as a separate taxon, King Blue is identified with P. ostreatus and is therefore useful when comparing named forms within the broader oyster group. The designation is particularly associated with deep blue coloration that can shift toward smoky silver, making it a useful search term for collectors researching blue oyster lines, Pleurotus ostreatus varieties, and related cold tolerant forms.
