Natural Habitat: An annual mushroom,
growing on a wide variety of woods, typically
on dead or dying trees, primarily on deciduous

woods, especially oak, maple, elm, willow,
sweetgum, magnolia, locust, and in the Orient,
on plums. Found on stumps, especially near the
soil interface, and occasionally on soils arising

from buried roots. Occurring from May
through November, and more common in
warm temperate regions. In the southeastern
and southwestern United States, Ganoderina
lucidum is frequently found in oak forests. In
the northeastern states, this species is most

common in maples groves. This mushroom often rots the roots of aging or diseased trees, causing them to fall. (This is one of the "white rot" fungi
foresters know well.) From the darkened cavity of the upturned root wad, where carbon dioxide levels
are naturally higher and light levels are low, long stalked mushrooms arise. These rare, multi-headed,
antler-like forms are highly valued in Asia. (See Figure 316.)
Microscopic Features: Spores reddish brown, ellipsoid with a blunted end, roughened as in warty, 9two walled, with spaced, internal "inter-wall pillars". Cystidia absent. Clamp
12 x 5.5-8
connections present, otherwise hyphae aseptate. Hyphal system dimitic. Chlamydospores forming in
cultured mycelium.

Available Strains: Yellow, red, purple, and black strains are widely available from most culture libraries. New strains are easily cloned from the wild, best taken from young fruitbodies from the
central flesh leading to the disc or alternatively from the edge of the developing cap margin. Because
of their woody texture, a sturdy and razor-sharp surgical scalpel is recommended. Recovery or "leapoff' may take two weeks. Once in culture, many strains grow rapidly and fruit on sawdust substrates.
Each tissue culturist should note that those strains isolated from conifers may actually be Ganoderma
oregonense or Ganoderina tsugae. Forintek's 34-D produces a reddish brown fruitbody and is popular amongst North American cultivators. American Type Culture Collection's #524 12, which was
used as the isotype for a taxonomic discussion by Wright & Bazzalo (Mycotaxon 16: 293-295, 1982)
produces a multitude of rapidly grown antlers. (See Figure 323).
Each strain is unique in its pattern of growth from agar media-to-grain-to-wood based substrates .A
notable difference between strains is that one group, when over-incubated, makes grain spawn nearly
impossible to loosen into individual kernels upon shaking. The other, smaller group of strains allows
easy separation, even when over-incubated.

Mycelial Characteristics: Longitudinally radial, non-aerial, initially white, rapid growing, becoming densely matted & appressed, yellow to golden brown, and often zonate with age. Some strains
produce a brown hymenophore on MEA. A 1 cm. square inoculum colonizes a 100 x 15 mm. petri
plate in 7-10 days at 750 F. (24° C.). Soon after a petri plate is colonized (2 weeks from inoculation),
