ALTERNATIVE SPAWN MEDIA
Some mushroom species do not grow well on grain and are better suited to alternative spawn

media. Other mushrooms are grown on substrates incompatible with grain spawn. For example,
sawdust and bran are the preferred spawn materials for the cultivations of wood inhabitors such as
Lentinus edodes and Flammulina velutipes. Another spawn media has a perlite bran base. Perlite is
vitreous rock, heated to 1000°F. and exploded like popcorn. The thin flakes of bran are readily
sterilized while the perlite gives the medium its structure. The recipes are:

Sawdust/Bran Spawn
4 parts sawdust (hardwood)
part bran (rice or wheat)
1

Soak the sawdust in water for a least
twenty four hours, allow to drain and then
thoroughly mix in the bran. If the mixture has
the proper moisture content, a firm squeeze
results in a few drops between the fingers. Fill
the material firmly to the neck of the spawn

container (wide mouth). Japanese spawn
makers bore a ½ inch diameter hole down
the center of the media into which they later
insert their inoculum. Sterilize for 60-90 minutes at 1 5 psi. Once cooled, inoculate from
agar media, liquid emulsion, or grain. A fully
grown bottle of sawdust bran spawn can also
be used for further inoculations.

Perlite Spawn
120 milliliters water
40 grams perlite
50 grams wheat bran
6 grams gypsum (calcium sulfate)
1 .5 grams calcium carbonate

Screen the perlite to remove the fine
powder and particulates. Fill the container
(small mouth) with the dry ingredients and
mix well. Add the water and continue mixing

until the ingredients are thoroughly moistened. Sterilize for one hour at 15 psi. Inoculate from agar media or liquid emulsion.
