212/The Mushroom Cultivator
Method of Preparation: Either chopped or whole straw is adequate, although permeation is more
rapid on the former. (See Chapter VI on preparation of straw as a fruiting substrate). Pasteurization
is achieved through the submersion of straw info a hot water bath at a temperature of 1 60°F. for
20-30 minutes. The straw, once pasteurized and inoculated, should be compacted and filled to a
depth of 6-12 inches. Gramss (1979) noted that wheat straw supplemented with 25% Fagus sawdust enhanced yields. Watling (1 980) reported, without elaboration, that fruitbodies form on a sawdust based medium. This species also fruits on unpasteurized straw although problems with insect
pests and competitor molds are more pronounced.

Spawn Run:
Relative Humidity: 90+%.
Substrate Temperature: 76-82°F. Thermal death limits have been reported as low as 90°F.
and —5°F.
Duration: 2-4 weeks.

C02: 5000-10,000 ppm.
Fresh Air Exchanges: 0 per hour.
Type of Casing: After fully run, cover with peat/humus (1:1) casing. Optimally, the casing should
have a pH of 5.7-6.0. (Because calcium based buffers inhibit fruiting, adjust the casing's pH by increasing or decreasing amount of peat). Balance to a 70-75% moisture content. Layer to a depth of
1 -2 inches. Humus should be pasteurized to kill nematodes, mites, and other parasites. Some
strains form fruitbodies solely on a peat casing. (Mushrooms do not form, however, on sterilized
casing. Hence, if the casing must be treated, steam pasteurization is recommended).

Post Casing/Prepinning:
Relative Humidity: 90+%.
Bed Temperature: 76-82 °F.
Duration of Case Run: 10-12 days.
C02: 5000-10,000 ppm.
Fresh Air Exchanges: 0 per hour.
Light: Incubation in darkness.

Primordia Formation:
Relative Humidity: 95+ %.
Air Temperature: 55-62 °F.
C02: less than 1000 ppm.
Fresh Air Exchanges: 2-4 per hour.
Watering: Regular misting (once to twice daily) to help stimulate primordia formation.
Light: Indirect natural or exposure to grow-lux type fluorescent for 1 2 hours/day.

Cropping:
Relative Humidity: 85-92%.
