our sample has now been reduced from an
original 6 lbs. to 1.5 lbs. At this stage, the remaining material, without supplementation,
supports vigorous growth of the King

Stropharia (Stropharia rugoso-annulata) or
the Shaggy Mane (Coprinus comatus). Once
colonized, the mycelium of these species are
best used as spawn to inoculate outdoor substrates. At this final stage, the nutritional base
of the substrate is largely expired, and subsequent fruitings are anemic.
In all, more than 20% of the substrate (dry
weight to dry weight) is converted into edible
mushrooms.At least that amount is liberated as
gases. The remaining material can be added to
garden composts as a supplement. The process
of reduction/conversion is substantially prolonged if the cultivator utilizes large-particle
wood chips in the original substrate formulas.
If the waste wood substrate is further supple-


benefit when nature is used as an ally. The implanted blocks of mycelium have the ability to
draw additional nutrients from the surrounding
habitat. By launching the expired blocks from

the growing rooms into supportive outdoor
habitats, the cultivator maximizes the potential
of the mycelial mass. One of my Natural Culture beds has supported a succession of three
species—first Morels in the spring, then King
Stropharia in the summer, and an assortment of
Hypholoma and allied species in the fall. This
approach could be called the Zen of mushroom

Whatever path is chosen, the implications
are profound. These courses of decomposition
are occurring daily in our forests' ecosystems.

Ecologists should also find this model especially fascinating in understanding the
concurrence of many species living in the same

habitat. This model may also be useful for
those living in desert, island, or other environ-

This is but one path of species sequencing.
