ease of use. When holes are punched through
the plastic, mushrooms emerge soon thereafter.
Opaque, black bags encourage photosensitive
strains of mushrooms to form only where the
holes allow light exposure. Clear bags stimu-

late maximum populations of mushroom
primordia but often times primordia form all over.
Cultivators must remove the appressing plastic or

selectively release colonies of primordia with
sharp blades to insure crop maturity. However,
many cultivators overcome this problem by using
select Oyster strains that localize primordial clus-

ters at exactly the puncture sites. By punching

dozens of holes with stainless steel, four-

of cellophane is that mushroom mycelium digests it in the course of its use. With mushrooms

having such great potential for recycling
wastes, it is ironic that non-recyclable plastics
fill so critical a need amongst cultivators. Some
ingenious re-structuring of cellulose could satisfy this increasing market for the
environmentally sensitive.
Bag culture first became popular for the Button mushroom industry and is still used to this
day. Inoculated compost is filled into and bags
topped with a soil-like casing layer. (See Figure
165. ) Individual bags are grouped on horizontal shelves. By preventing contact between the
mycelium and the wooden shelves, contamination, especially from the wood-loving
Trichoderma and Botrytis molds, is minimized.
Many growers favor plastic bags for their
