Growing Parameters for Various Mushroom Species! 173

NATURAL HABITAT: Common across the North American continent and in other temperate to
boreal regions of the world. Thriving on woody tissue, especially living trees and considered a cold
weather mushroom.

GROWTH PARAMETERS
Mycelial Types: Linear to cottony mycelia, sometimes aerial.
Spawn Medium: Sawdust/bran. One liter (1000 ml.) bottle of spawn inoculates 50-1 60 (800
ml.) containers. See Chapter III.

Fruiting Substrate: A 80-90% hardwood sawdust and 10-20% rice bran medium. Newly
chipped sawdust holds moisture poorly and some Japanese growers age the sawdust for several
years before using. Standard fruiting containers are quart mason jars or 800 ml. small mouthed
plastic bottles. Some growers are currently experimenting with the cultivation of this species on bulk
substrates in trays. Adjust moisture content of substrate to 58-60%.

Method of Preparation: See Chapter III for the preparation of sawdust/bran media. A 4:1 volumetric ratio of sawdust to bran (equivalent to a mass ratio of 1 0:1 sawdust to bran) is recommended.

Sterilize for 1 -2 hours at 250 °F. (1 5 psi).

Spawn Run:
Relative Humidity: 90-100%.
Subs trate Temperature: 72-77 °F.
Duration: 20-30 days using standard methods; 12-13 days using in vitro inoculation methods.

C02: 5000-10,000 ppm.
Fresh Air Exchanges: 0 per hour.

Type of Casing: None required.

Primordia Formation:
Relative Humidity: 85%.
Air Temperature: 50-55 °F.
C02: less than 1000 ppm.
Fresh Air Exchanges: 4 per hour.
Light: None needed.

Cropping:
Relative Humidity: 85%
Air Temperature: 50-55 °F.
Duration: 2-3 weeks.
CQ2: less than 1000 ppm.
Fresh Air Exchanges: 4 per hour.
Light: Natural daylight or grow-light on a 12 hour cycle on/off cycle.
Flushing Interval: 1 0 days.
