Coprinus comatus : Shaggy Mane Mushroom Culture Slant

Culture supplied as living mycelium in a test tube slant. Culture can be stored under refrigeration for several months. Slants are best suited for long distance travel, or long term culture storage. To ensure freshness of culture, slant requests are made to order, please allow 2-4 weeks for processing and shipment.

Substrate: Straw and composts, sterilized sawdust
Colonization/Fruiting Temperatures: 70-80F/58-65F

The Shaggy Mane is one of the best known wild mushrooms. It is rarely found for sale as a fresh mushroom because of its poor keeping qualities. It has a curious habit of melting into a black goo as it matures. This is not decay but a natural autodigestive (deliquescence) process that helps disperse the mushroom's spores. To secure a supply they must be hunted or cultivated at home.

We have seen reliable results from a buried large straw-based MycoBag(TM) colonized with Shaggy Mane mycelium via culture syringe injection. The fully colonized substrate block should be removed from the bag and buried in the spring, preferably in an outdoor household compost pile. Shaggy Manes are thermotolerant and seem to be stimulated by the ammonia production in active compost piles (although they can't survive peak heating). Mycelium planted in the spring should produce mushrooms the following autumn.

Reportedly, Shaggy Mane mushrooms can be fruited indoors using the same substrates and techniques used for the common button mushroom Agaricus bisporus. This requires environmental temperatures much lower than normal room temperatures which limits its cultivation to those with cool basements, unheated outbuildings or a precisely temperature controlled fruiting environment. We have yet to attempt this in our labs.

Mushrooms should be harvested at a young age.

The culture offered here has been isolated from a wild collection in Oregon, USA.
