Product Title: Chocolate Oyster "PO-ME1" Pleurotus ostreatus Mushroom Agar Culture
Transfers made to order: on MYA plate
A deep-capped, fast-colonizing Pleurotus ostreatus strain sourced from Maine Cap n Stem — and one I've been actively fruiting here in Jacksonville with strong results. This is Chocolate Oyster doing what good genetics do: colonizing fast, pinning reliably, and producing yields that make the work worth it.
Chocolate Oyster is a brown-capped phenotype of Pleurotus ostreatus : the same species as Blue Oyster, but with darker pigmentation, a slightly denser texture, and a visual profile that stands out on any market table or plate. Same gourmet quality, same beta-glucan and protein content, different character.
What's standing out in my runs: aggressive mycelial growth from inoculation through colonization, strong yields on first flush, and performance in Florida ambient conditions that would stress a lot of standard Oyster strains. The mycelium on this one moves with purpose.
Originally from Maine Cap n Stem — a cultivator worth knowing. Grown out and worked here at SFF in the Florida heat.
Cultivation Overview
Chocolate Oysters grow well on a wide range of substrates — straw, supplemented hardwood, HWFP, and master's mix all work. This is a forgiving, productive species and a solid choice for growers at any level. Colonization is fast and the mycelium is vigorous, so expect a quick turnaround from inoculation to fruiting.
Fruiting Conditions
Temperature: 55–85°F (performing well in Florida ambient conditions)
Humidity: 60–95% relative humidity during fruiting
Light: Indirect or diffused light is sufficient
Fresh Air Exchange: Moderate to high — encourages proper cap development and prevents overlay
Characteristics
Sourced from Maine Cap n Stem, grown out by SFF
Deep brown cap pigmentation — distinctive market and plate appearance
Aggressive mycelium, fast colonization
Strong yields, reliable flushes
Florida heat performance documented
Ideal For
Gourmet mushroom growers
Farmers market and restaurant producers
Oyster mushroom collectors and breeders
Growers in warm or Southern climates
Chocolate Oyster is one of those strains that earns its place in the rotation — productive, good-looking, and built for growers who want results.
Grow clean cultures. Grow proven genetics.
