Organic Coprin Mushroom Grain Spawn

Hairy coprin, coprinus comatus

Easy to grow, the hairy mushroom is a very fragile but delicious mushroom. Its shelf life limited to 1-2 days explains why it is almost not marketed. However, it is a good edible and its flavor is excellent. It has a melting texture at the cap, while the feet remain crunchy.

It is generally a litter fungus that appreciates substrates rich in nitrogen and organic matter. It is often found near compost, old manure, and grazed meadows. After harvesting, coprin tends to liquefy quickly and form a sort of black ink. This is its natural spore dispersal process. It must therefore be harvested very young before the edges of the caps begin to blacken and stored directly in the refrigerator. 

Young hairy goats can be cut into strips and dried for better conservation.

When the coprin has established itself well in outdoor cultivation, it can bear fruit for several consecutive years.

Growing conditions

It can be grown indoors or outdoors.

Substrates

Mixture of straw and compost, manure, or other materials rich in nitrogen.

In indoor cultivation the substrates are pasteurized for 30-60 minutes at 70° before being sown and placed in trays. After colonization, the substrate must be covered with a layer of casing which can consist of peat, or simply potting soil.

Some also mix gypsum or (slaked) lime into this casing layer.

In outdoor cultivation, it is also possible to have satisfactory results without pasteurization of the substrates.
