1. Spawn

Welcome to Mushroompeople! Spawn is the mushroom culture in bulk, the “seed” material used to cultivate mushrooms in logs, sawdust, straw, or other media. Spawn can be stored for 2 to 3 months at 34–41° F, if unopened, or about a week once opened. Do not freeze! Plug (dowel) spawn is only available for shiitake. All our species are available in sawdust spawn, and we sometimes feature grain spawn for Tree Oyster.
