ability to give rise to volunteer primordia on
nutrified agar media, once characteristic of a
strain, declines or disappears entirely. Speed of
growth decelerates. If not entirely dying out, the

strain is reduced to an anemic state of slow
growth, eventually incapable of fruiting. Prone
to disease attack, especially by parasitic bacteria, the mushroom strain usually dies.

Color: Most mushroom species produce
mycelia that undergo mesmerizing transforma-

tions in pigmentation as they age, from the
youngest stages of growth to the oldest. One
must learn the natural progression of colorations for each species' mycelium. Since the
cultivator is ever watchful for the occurrence of
certain colors which can forebode contamina-

tion, knowing these changes is critical.
Universally, the color green is bad in mushroom

culture, usually indicating the presence of

Mushroom strains, once characterized by
rhizomorphic mycelia, often degenerate after
many transfers. Usually the decline in vigor fol-

develops mycelium with aerial tufts of cottonlike growth. The mycelium at the center of the
petri dish, giving birth to these fans of disparate growth, is genetically unstable, and being
in an active state of decline, sends forth muta-

tion-ridden chains of cells. Often times, the
