The book first guides readers through an in-depth exploration of indoor and outdoor cultivation. Covered skills range from integrating wood-chip beds spawned with king stropharia into your garden and building a “trenched raft” of hardwood logs plugged with shiitake spawn to producing oysters indoors on spent coffee grounds in a 4×4 space or on pasteurized sawdust in vertical plastic columns. For those who aspire to the self-sufficiency gained by generating and expanding spawn rather than purchasing it, Cotter offers in-depth coverage of lab techniques, including low-cost alternatives that make use of existing infrastructure and materials. 

Cotter also reports his groundbreaking research cultivating morels both indoors and out, “training” mycelium to respond to specific contaminants, and perpetuating spawn on cardboard without the use of electricity. Readers will discover information on making tinctures, powders, and mushroom-infused honey; making an antibacterial mushroom cutting board; and growing mushrooms on your old denim jeans.

Geared toward readers who want to grow mushrooms without the use of pesticides, Cotter takes “organic” one step further by introducing an entirely new way of thinking―one that looks at the potential to grow mushrooms on just about anything, just about anywhere, and by anyone.
