The Stock Culture Library:
A Genetic Bank of
Mushroom Strains


very sexually reproducing organism on this planet is limited in

the number of its cell replications. Without further recombination of genes, cell lines decline in vigor and eventually die. The same
is true with mushrooms. When one considers the exponential expan-

sion of mycelial mass, from two microscopic spores into tons of
mycelium in a matter of weeks, mushroom mycelium cell division
potential far exceeds that of most organisms. Nevertheless, strains
die and, unless precautions have been taken, the cultures may never
be retrieved.
Once a mushroom strain is taken into culture, whether from spores
or tissue, the resultant strains can be preserved for decades under
normal refrigeration, perhaps centuries under liquid nitrogen. In the
field of mycology, cultures are typically stored in test tubes. Test tubes
are filled with media, sterilized and laid at a 15-20 degree angle on a
table to cool. (Refer to Chapter 12 for making sterilized media.) These
are called test tube slants. Once inoculated, these are known as culture slants.
