SPECIES:

Pleurotus ostreatus (Jacq. ex Fr.) Kummer (Florida
variety)
= Pleurotus ostredtus var. florida nom. prov. Eger
= Pleurotus floridanus Singer

STRAINS: Most strains of this mushroom originate from wild specimens cultivated in 1 958 by
S.S. Block of Gainesville, Florida. Eger compared the Florida strains with Pleurotus ostreatus from
Michigan (supplied by Alexander Smith) and found them to be identical in form, taste, color and
odor. Spore size and shape are also the same. Monokaryons arising from single spore germinations
are completely cross fertile, suggesting that these two mushrooms are not separate species, but different strains within the same species.

The American Type Culture Collection, which sells cultures to educational organizations and
research facilities, lists this mushroom under Pleurotus ostreatus as number #38538. This strain is

Block's original. Eger returned to Florida with San Antonio in 1977 and recollected four more
ATCC

strains of Pleurotus, three of which were deposited with ATCC. They are respectively: Fl

#38539; F2 = #38540; F4 = #38541.
The Florida Pleurotus is available as commercial spawn from Somycel as #3025. The Swiss
American Spawn Company sells a "low spore load" strain called P-3.

COMMON NAME: Pleurotus Florida. The Florida Pleurotus.
LATIN AND GREEK ROOTS: Pleurotus comes from the Greek "pleuro" which means formed
laterally or in a sideways position, referring to the lateral position of the stem relative to the cap. The
epithet Florida obviously refers to the locality where this mushroom was first collected.

GENERAL DESCRIPTION: Cap tongue shaped, maturing to a shell shaped form, 50-100 mm.
in diameter; whitish to gray to pale yellow brown. (Color is a light and temperature determined factor in this species). The flesh is thin and white. The margin is even and occasionally wavy. The gills
are white, decurrent and broadly spaced. The stem is attached in an off-centered fashion and is short
at first and absent in age. Its spores are whitish to lilac gray in mass.

NATURAL HABITAT: A wood decomposing, saprophytic or parasitic fungus. Pleurotus
ostreatus grows abundantly on standing and fallen alder, cottonwood and maple. This species is especially numerous in river valleys and fruits in the fall, early winter and spring in subtropical environs.

GROWTH PARAMETERS
Mycelial Types: Fast growing rhizomorphic to linear mycelia. Its color is typically whitish.
Standard Spawn Medium: Rye grain. See Chapter III.
Fruiting Substrate and Method of Preparation: Cereal straw (normally wheat) balanced to a
75% moisture content. The straw, chopped or whole, is pasteurized by submerging in a 1 60°F.
