Mississippi Mushrooms: Part Compost Heap, Part Laboratory

Describing itself as “part compost heap, part laboratory,” northeast Minneapolis–based Mississippi Mushrooms is on a mission to recycle organic waste such as sawdust and leftover brewer’s grain from local businesses to fuel its fungi-growing operation. Mississippi Mushrooms cultivates such exotic-looking (and -tasting) varieties as the oblong king oyster and shag-covered lion’s mane for Twin Cities restaurants and co-ops, and now sells them from its warehouse the fourth Wednesday of every month—just in time for mushroom-soup season.
