162/The Mushroom Cultivator

GENERAL DESCRIPTION: Cap smooth, white, thick fleshed, convex to broadly convex to plane
with age. The cap margin is incurved at first but soon decurves. The gills are pinkish at first, soon
darkening to chocolate brown with spore maturity. The stem is thick, relatively short and adorned
with a double membranous annulus. (The lower ring is often a thin annular zone). Its spores are
dark chocolate brown in mass.

NATURAL HABITAT: Naturally found in lawns, gardens, roadside areas, pastures, in enriched
grounds and on hard packed soil. A temperate species, widely distributed, A. bitorquis fruits primarily in the spring and to a lesser degree in the fall.

GROWTH PARAMETERS
Mycelial Types: Rhizomorphic to linear; whitish to pale whitish in color.
Spawn Medium: Rye grain buffered with calcium carbonate and/or calcium sulfate. See Chapter

Fruiting Substrate: Nitrogen enriched wheat straw and/or horse manure based compost balanced to 71-74% moisture content.

Method of Preparation: See Chapter V on compost preparation. Pasteurization achieved
through exposure to live steam for 2 hours at 1 40
