Oysters (Pleurotus ostreatus) can be grown in pasteurized hardwood sawdust or straw, in 6′ tall column bags. A 5-lb. bag of grain spawn will inoculate from 200 to 400 lbs. of dry substrate. Fruits at 60-70º F. 5 lb.

Please also see our Book section for GROWING GOURMET & MEDICINAL MUSHROOMS 3rd Ed. by Paul Stamets, a beautiful illustrated manual for all methods of growing many types of mushrooms. 585p.

Pleurotus ostreatus grows well in softer hardwoods like poplar. Sawdust spawn only.

The Black Morel (Morchella angusticeps), like the other morel species, is quirky and unreliable because it has not been cultivated for decades like shiitake and oyster mushrooms. However, their unique zesty flavor keeps people trying and sometimes succeeding in growing these delicacies of the forest. Morels are grown in the soil, in areas sheltered from strong wind but not necessarily clear of grasses or trees. Detailed instructions are provided with your order.
