Compost/Manure Mushroom

This mushroom requires a special substrate containing around 20% leached and dried manure or compost.

Our Wine Cap Mushroom Grain Spawn is grown on 100% certified organic rye berries. It arrives contaminate free, fully developed, and ready to use. Wine Cap Mushroom Grain Spawn is used to inoculate many bags of bulk substrate quickly. Transferring grain into bulk substrate bags is the choice methodology for medium and large scale growers. Wine Cap Mushroom Grain transfers are usually performed in a flow-hood or bio-cabinet. Simply break up the Wine Cap Mushroom Grain Spawn, then transfer grains to each bag you want to inoculate.


The king stropharia can grow to 20 cm high with a reddish-brown convex to flattening cap up to 30 cm across, the size leading to another colloquial name godzilla mushroom. The gills are initially pale, then grey, and finally dark purple-brown in colour. The firm flesh is white, as is the tall stem which bears a wrinkled ring. This is the origin of the specific epithet which means "wrinkled-ringed". It is found on wood chips across North America in summer and autumn. Described as very tasty by some authors, king stropharia is easily cultivated on a medium similar to that on which it grows naturally. Antonio Carluccio recommends sautéeing them in butter or grilling them.
