Pleurotus ostreatus var. columbinus Culture
Common name: Blue Oyster
Fruiting Temperature: 45–65 °F
A cool-weather variant of P. ostreatus, the Blue Oyster is similar in appearance and culinary characteristics. Cultivation strategies closely parallel that of the Pearl Oyster. Great for outdoor cultivation in cooler climates.
Fungi Perfecti is constantly working with these strains, screening and maintaining cell lines. Fungi Perfecti is releasing the following strains for use on a conditional basis.
Each order of in vitro mushroom cultures is custom-made: lead time for cultures is 6–8 weeks from date of order.
Please note: Unlike our ready-to-grow Mushroom Patches and Mushroom Plug Spawn, our cultures do not come with instructions. It is assumed that the purchaser is sufficiently familiar with mushroom culture technique to utilize these cultures. The books Growing Gourmet & Medicinal Mushrooms and The Mushroom Cultivator are essential tools in this endeavor.
By purchasing these cultures, the customer agrees to the terms of the Mushroom Culture Sale Agreement. Each strain is designated with the Stamets P Value® scale, signifying the expansion of mycelium covering a 100 x 15 mm petri dish (approximately 1,000–2,000 cell divisions). The first time a wild species is tissue cultured, the age is denoted as P-O. Thereafter each successive growth over the petri dish's surface is described in increments of P-l, etc. This library tries to maintain strains closest to their wild origins or closest to their peak fruiting potentials. Each culture comes in a 125 x 20 mm glass test tube.

This affects the sale of Fungi Perfecti's Plug Spawn for Log and Stump Cultivation and Pure Mushroom Spawn and Cultures. Customers in Hawaii wishing to purchase any of these products will need to first apply for and receive an Import Permit from the HSDA Plant Quarantine Branch. Additionally, importation of our MycoGrow™ products is completely prohibited.
