Cropping Cycle:
Two to three flushes, four to ten days apart.

Available Strains: This mushroom is easy to clone. Cultures are widely available from libraries
throughout the world. However, a sporeless strain is needed before dommercial cultivation will become practical. I have isolated a late-sporulating strain from a fruiting on manure enriched sawdust.
Sporeless strains are needed as the maturing spores trigger deliquescence, causing the mushrooms to
disintegrate into a black spore-enriched fluid. This spore liquid presents unique problems to cultivators in their attempts to isolate spores away from contaminants.

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. (See Figure 198).

Fragrance Signature: Farinaceous and mildly sweet.

Natural Method of Cultivation: Inoculation of spawn directly into manure enriched soils or 4-6
inch deep beds of hardwood sawdust. Newly laid or fertilized lawns that are frequently watered are
perfect habitats for Shaggy Manes. Cow or horse manure, mixed with straw or sawdust, are also ideal.
