duce odors which humans can recognize elsewhere in our life experiences. Some
mushrooms smell like radishes, some like apricots, and even some like bubble gum! Is there
any significance to these odors? Or is it just a
fluke of nature?

The Event of Volunteer
Primordia on Nutrified
Agar Media
The voluntary and spontaneous formation of

miniature mushrooms in a petri dish is a delightful experience for all cultivators. In this
chapter, attention and insights are given for
many species. By no means is this knowledge
static. Every cultivator contributes to the body
of knowledge each time a mushroom is cultured
and studied.
The cultivator plays an active role in devel-

oping strains by physically selecting those
which look "good". Integral to the success of
the Mushroom Life Cycle is the mycelial path
leading to primordia formation. To this end, the

mushroom and the cultivator share common
interests.The occurrence of primordia not only
is a welcome affirmation of the strain's identity
but is also indicative of its readiness to fruit.
Hence, I tend to favor strains which voluntarily form primordia.
Two approaches lead to primordia formation
from cultured mycelium. The first is to devise
a standard media, a background against which
all strains and species can be compared. After
performance standards are ascertained, the second approach is to alter the media, specifically

improving and designing its composition for
the species selected. As a group, those strains
needing bacteria to fruit do not form primordia
on sterile media.
Several mushroom species have mycelial
networks which, when they are disturbed at primordia formation, result in a quantum leap in
the vigor of growth and in the number of subsequently forming primordia. With most strains
however, the damaged primordia revert to vegetative growth.The following list of species are
those that produce volunteer primordia on 2%
enriched malt extract agar, supplemented with
.2% yeast and .005% gentamycin sulfate. *The

formation of primordia on this medium is of-

ten strain specific. Those species in bold
lettering are known by this author to benefit

from the timely disturbance of primordia.
Those which do benefit from disturbance are
excellent candidates for liquid inoculation techniques.
