is introduced. Consequently, several other
phenomena occur: evaporation is increased,

photosensitive after it has achieved a threshold
critical mass, usually coincident with full colo-

humidity drops, temperature changes, and the
net number of contaminant particles entering
the growing room rises as air exchanges are
Temperature: As a general rule, incubation
temperature runs higher than the temperature
for primordia formation. Internal temperatures
should not exceed 95° F. (35° C.) or black pin
molds and other thermophilic competitors will
awaken, especially under the rich CO2 conditions created as a by-product of spawn running.
Lighting: For the species described in this
book, moderate lighting has no effect, adverse

nization, and after carbon dioxide evolution

or advantageous, on the mycelium during
spawn run. Bright, unfiltered, direct sunlight is

damaging. Light is especially harmful when
intensities exceed 10,000 lux. From my experi-

ences, the mycelial mat only becomes

has steeply declined.

The Initiation Strategy
By far the most critical step is that of primordia formation, called the initiation strategy. An

initiation strategy can be best described as a
shift in environmental variables, triggering the
formation of mushrooms. The four major envi-

ronmental factors operative in an initiation
strategy are: moisture, air exchange, temperature and light. These are adjusted accordingly:
Moisture: Direct watering is applied,

coupled with a constant, controlled rate of
evaporation to maintain high humidity between 95-100%. Fog-like conditions are
