1. Spawn

1. Spawn 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 or dowel spawn is available for shiitake only. All the other spawn species we have are in sawdust spawn, and, in the case of Tree Oyster, we also stock grain spawn.
