Species & Strain

Processing times

Culture plates are ideal for growers looking to make master bags, inoculate grain, make liquid culture, or make more plates.

Chestnut culture plates are made to order and have a shelf life of approximately 6 months. They should be stored in the refrigerator to maintain viability. Note that mycelium cultures require basic lab skills. Handle using sterile technique to prevent contamination.

See full description of each chestnut strain available below.

NSPA2 - Cap 'n Stem Chestnut

Pholiota adiposa. A commercial strain from fellow Maine producers Cap N' Stem. Clustering, wood-loving mushroom forms dense clusters of dark orange gilled mushrooms with a slightly shaggy cap. Prefer cooler temperatures and typically take 2-3 weeks to mature once they start to fruit.
