Sporeless Oyster Mushroom Plate Culture

Sporeless Oyster Mushroom (Pleurotus ostreatus) Mushroom Plate Culture.

Each culture plate is a 100x15mm petri dish inoculated with fresh Sporeless Oyster Mushroom (Pleurotus ostreatus) mycelium growing on malt extract agar (MEA), and will arrive actively colonizing.

Sporeless Oyster Mushroom Plate Culture Lab Notes

At Out-Grow's mycology lab, we have observed the following traits of this mushroom plate culture:

Sporeless Oyster Mushroom (Pleurotus ostreatus) mycelium appears bright white on culture media, with a dense, cottony texture that rapidly becomes rhizomorphic with prominent ropey strands — consistent with standard P. ostreatus behavior, as sporeless strains show no documented deviation in mycelial appearance on agar. Growth is fast and vigorous at an optimal temperature of 72–79°F. The key distinction of sporeless strains is the absence of functional spore production in fruitbodies, which reduces airborne spore loads in grow rooms. Because sporeless strains cannot be reliably propagated from spores, maintaining healthy master agar cultures with regular backups is especially critical to avoid loss of the clone.

Mushroom Plate Culture Use

Mushroom plate cultures, typically on MEA culture plates, are used to grow and preserve mycelium. In most cases, sterile transfers of agar wedges from this plate are used to inoculate fresh culture media or sterilized grain spawn.

Mushroom Plate Culture Storage

Your mushroom plate culture can be wrapped in parafilm and stored at normal room temps, in a sealed baggie, for up to 6 months. Out-Grow recommends you replate your mushroom plate culture every 6 months to ensure longevity of your purchase.

Store fully colonized plates at 35–41°F in darkness, sealed to prevent desiccation. Working plates should be refreshed every 2-3 months; maintain multiple backup cultures given that this clone cannot be recovered from spores.

Mushroom Plate Cultures Are Made to Order

All mushroom culture plates are made to order. Once your order is received, Out-Grow will inoculate your plate within 1-3 days. Your mushroom plate culture will then be incubated in our mycology lab for approximately 7-14 days, or until clean healthy mycelium has been verified by our mycologist. Once verified, your order will be shipped promptly. Please allow an additional week for your mushroom plate culture to fully colonize upon arrival, as colonization time varies by species.
