recycling, data on toxin residues is readily
available. (If the data can not be validated, or
is outdated, the use of such newsprint is not

recommended.) Since the use of processed
wood fiber may disqualify a grower for state

organic certification, cultivators in the
United States should check with their Organic Certification Director or with their

manner not to encourage composting. Once weed
fungi, especially black and green molds, begin to
proliferate the suitability of these base materials

is jeopardized. At present, the only mushrooms
demonstrating commercial yield efficiencies on
banana and coffee pulp are warm-weather strains

Carrera (1987).
Sugar cane bagasse Sugar cane bagasse is the
major waste product recovered from sugar cane
harvesting and processing. Widely used in Ha-

Corncobs & cornstalks Corncobs (sans
kernels) and cornstalks are conveniently
structured for rapid permeation by mycelium.

Their cell walls and seed cavities provide a
uniquely attractive environment for mycelium. Although whole corncobs can be used
directly, a more uniform substrate is created
by grinding of corncobs to 1-3 inch particles
using hammer-mill type chipper-shredders.
After moistening, the corn roughage can be

cooked for 2-4 hours at

F. to

achieve pasteurization. If the kernels are still

on the cob, sterilization may be necessary.
Cornstalks, having a lower nutritional content, are less likely to contaminate.
Coffee & banana plants In the subtropical

and tropical regions of Central and South
America, the abundance of coffee and banana
leaves has spurred mycologists to examine their
usefulness in growing gourmet mushrooms.
The difficulty in selecting any single plant material from warm, humid regions is the speed of
natural decomposition due to competitors. The
combination of high humidity and heat accelerates

decomposition of everything biodegradable.
Leaves must be dried, shredded, and stored in a

please refer to Thielke (1989), or Martinez-

waii and the Phiffipines by Oyster growers, sugar
cane bagasse needs only pasteurization for cul-

tivating Oyster mushrooms. Some Shiitake
strains will produce on sugar cane residue, but
yield efficiencies are low compared to wood-

based substrates. Since the residual sugar
stimulates mycelial growth and is a known trigger to fruiting, sugar cane residues are good
complements to wood-based substrates.
Seed hulls Seed hulls, particularly cottonseed
hulls, are perfect for their particle size and their
ability to retain water. Buffered with 5-7% calcium sulfate and calcium carbonate, cottonseed

hulls simply need wetting, pasteurization and
inoculation. Cottonseed hulls, on a dry weight
basis, are richer in nitrogen than most cereal
straws. Many Button cultivators consider cotton-

seed hulls a supplement to their manure-based
composts. On unamended seed hulls, Oyster and
Paddy Straw are the best mushrooms to grow.
Peanut shells have had little or no value ex-

cept, until now, to mushroom growers. The
peanut hulls are rich in oils and starch which
stimulate mushroom growth.The shells must be
chipped into 1/4 to 3/4 inch pieces, wetted, and
