Genus species (Fungi): Ganoderma tsugae

Habit

In contrast to Ganoderma lucidum, to which it is closely related and which it closely resembles, Ganoderma tsugae tends to grow on conifers, especially hemlocks.

Properties

Like Ganoderma lucidum, Ganoderma tsugae is purported to have medicinal properties including use for dressing a skin wound. Phylogenetic analysis has begun to better differentiate between many closely related species of Ganoderma; however, there is still disagreement as to which have the most medicinal properties. In addition, variations within the same species as well as the growth substrate and environmental conditions all the way through to preparation can have a substantial effect on the medicinal value of the product.

Edibility

Like Ganoderma lucidum, Ganoderma tsugae is non-poisonous but generally considered inedible, because of its solid woody nature; however, teas and extracts made from its fruiting bodies supposedly allow medicinal use of the compounds it contains, although this is controversial within the scientific community. A hot water extraction or tea can be very effective for extracting the polysaccharides; however, an alcohol or alcohol/glycerin extraction method is more effective for the triterpenoids.

Medicinal use

Studies in mice has shown that Ganoderma tsugae shows several potential medicinal benefits including anti-tumor activity through some of the active polysaccharides found in Ganoderma tsugae. Ganoderma tsugae has also been shown to significantly promote wound healing in mice as well as significantly increase the proliferation and migration of fibroblast cells in culture.
