Coprinus Comatus
(Information taken from Paul Stamets: Growing Gourmet and Medicinal Mushrooms)
Shaggy Manes have long been a favorite amongst
mushroomers in North America and Europe. Easy to identify, often
growing in massive quantities, this brilliant white mushroom is hard to
miss and difficult to confuse with poisonous species. Their fragile
constitution and unique method of self-destruction, combined with their
mild but excellent flavor, has made the Shaggy Mane a popular mushroom
amongst hikers and hunters.
This species adapts to a wide
variety of indoor and outdoor substrates. Although the commercial
cultivation of this mushroom is limited by its predisposition to
disintegrate into an inky mess. This mushroom in fantastic for those
who can consume it within two days of picking.
Mycelial Characteristics: Mycelium usually white, cottony, aerial, often develops "tufts" (hyphal aggregates) with maturity. Most strains form mycelial mats asymmetrically shaped along the outer edge.
Microscopic Features: This mushroom produces black spores.
Suggested Agar Culture Media: Potato Dextrose Agar (PDA), Potato Dextrose Yeast Agar (PDYA), Malt Extract Agar (MEA), Malt Peptone Yeast Agar (MPYA), Dog Food Agar (DFA), or Oatmeal Yeast Agar (OMYA).
Spawn Media: Grain (rye, wheat, sorghum).
Substrates for Fruiting: The straw/manure compost can support substantial fruitings of this mushroom. Another excellent medium can be made from the manure and urea-enriched sawdust discharged from horse stables. Paper and pulp waste also support fruitings. Like most coprophiles, this mushroom greatly benefits from the placement of a peat moss based, casing soil.
Yield Potentials: When soya flour was added at a rate of 2 o paper pulp fiber (giving the substrate a 0.5 itrogen content), yields approached 80iological efficiency. However, these yields were lower than that generated from manure compost which often exceed 100iological efficiency.

Comments:
This is a great mushroom to grow in your yard and in compost piles.
Once an outdoor patch is established, Shaggy Manes can fruit for many
years. For impatient cultavators, indoor cultivation is recommended.
For mycological landscapers not concerned about territorial confinement
of their mushroom patch, the Shaggy Mane is an excellent companion to
garden plants.
After pasteurized compost is inoculated, the
substrate is completely colonized in two weeks with a cottony,
non-rhizomorphic mycelium. When colonization is complete, a moist
casing (peat moss/gypsum) layer is applied. After 10 days, the mycelium
can be seen reaching through the upper surface of the casing. At this
stage, lower the temperature, increase watering, and introduce light to
stimulate fruiting. Yields can be substantially increased if the casing
layer is vigorously raked just as the mycelium begins to show on the
surface of the casing.
The primordia form as circular dials,
between the size of a dime to a quarter. The primordia are unique in
that they are wide and flat. An inner collar forms within the dial and
arises to form a dome. This dome soon shoots up to form a recognizable
mushroom. The circular zone visible at the primordial stage becomes the
movable ring resting on the stem of the mature mushroom.
