scape, the inycosphere, will give rise to an even,
high-density population of rapidly forming primordia.Visible to the naked eye, the mycelium's
surface is punctuated with a lattice-work of val-

leys and ridges upon which moisture droplets
continually form, rest, and evaporate. In the
growing room this period corresponds to 98-100
% rH, or a condensing fog. Even in a fog, air cur-

rents have an evaporative effect, drawing
moisture to the surface layer. The careful management of this mycosphere, with high oxygen,
wicking, evaporation, and moisture replenish-

ment combined with the effect of other
environmental stimuli results in a crescendo of
primordia formation. Cultivators call these environmental stimuli, collectively, the initiation
Primordia, once formed, may rest for weeks,

depending upon the species and the prevailing
environment. In most cases, the primordia ma-

pairs of nuclei, and the cells expand, resulting
in an explosive generation of mushroom tissue.
As the mushroom enlarges, differentiation of

familiar features occurs. The cap, stem, veil,
and gills emerge. The cap functions much like
an umbrella, safeguarding the spore-producing

gills from wind and rain. Many mushrooms

showed that, with some mushroom species (i.
e. Psilocybe cubensis), cap orientation is foremost affected by the direction of air currents,
then by light, and finally by gravity. Beneath the
cap, the gill plates radiate outwards from a centralized stem like spokes on a wheel.
Over the surface of the gills, an evenly dis-
