Growth Parameters
Spawn Run:
Incubation Temperature: 70-80° F. (2 1-27° C.)
Relative Humidity: 95-100%
Duration: 14-2 1 days, + 7 day rest
CU2:> 10,000 ppm
Fresh Air Exchanges: 0-1
Light Requirements: n/a

Primordia Formation:
InitiationTemperature: 50-55° F. (10-13° C.)
Relative Humidity: 98-100%
Duration: 5-10 days.
CU2: < 1000 ppm
FreshAir Exchanges: 4-8 perhour or as needed
Light Requirements: 500-1000 lux

Fruitbody Development:
Temperature: 55-65° F. (13-18° C.)
Relative Humidity: (90) 94-98%
Duration: 4-7 days
CU2: 600-1500 ppm
Fresh Air Exchanges: 4-8 per hour or as needed.
Light Requirements: 500-100 lux.

Cropping Cycle:
Two crops, 7-10 days apart.

Recommended Cropping Containers: Polypropylene, autoclavable bags, bottles, and/or trays.
This mushroom grows well horizontally or vertically.

Yield Potentials: My yields consistently equal 1/2—1 lb. of fresh mushrooms from 5 lbs. of moist
Harvest Hints: I especially like this mushroom when it grows to a fairly large size, but prior to maximum sporulation. I gauge the thickness at the disc as the criterion for harvesting, preferring at least 2
inches of flesh.

Form of Product Sold to Market: Fresh, sold only in Japan and Taiwan at present.

Nutritional Content: Not known to this author.

Medicinal Properties: I know of no published studies on the medicinal properties of Hypsizygus
ulmarius. Anecdotal reports, unpublished, suggest this mushroom is highly anti-carcinogenic. Much
