establishing their own territorial domains. In
this sense, spores from one mushroom can actually compete with one another for the same
ecological niche.
Each mushroom is like an island. From this
center, populations of spores decrease with distance. When spores germinate, the mycelium
grows out radially, away from the site of origin.

Often times, the next hospitable environment
may be far away. Spores, taken up by the wind,
or carried by insects and mammals, are dispersed to habitats well distant from the parent
mushroom. By coincidence, different varieties
of the same species meet and exchange genetic
material. In the ever-changing ecological landscape, new varieties are favorably selected for
and survive. This diversity within a species is
critical to preserving its ability to adapt.

mushroom mycelium into the surrounding en-

Each spore that is released possesses one half
of the genetic material necessary for the propa-

gation of the species. Upon germination, a
filamentous cell called a hypha extends. Hyphae continue to reproduce mitotically. Two
hyphae, if compatible, come together, fuse, and
combine genetic material.The resulting mycehum is then described as being binucleate and
dikaryotic. After this union of genetic material,

the dikaryotic mycelium accelerates in its
growth, again reproducing mitotically. Mated
mycelium characteristically grows faster than
unmated mycelium arising from single spores.
The mating of compatible hyphae is genetically determined. Most of the gourmet species
are governed by two incompatibility factors (A
and B). As a result only subsets of spores are
able to combine with one another. When spores
germinate, several strains are produced. Incom-

patible strains grow away from each other,
