Lingzhi mushroom

Ganoderma lucidum

The lingzhi mushroom is a polypore mushroom belonging to the genus "Ganoderma". Its red-varnished, kidney-shaped cap gives it a distinct appearance. When fresh, the lingzhi is soft, cork-like, and flat. It lacks gills on its underside, and instead releases its spores via fine pores. Depending on the age of the mushroom, the pores on its underside may be white or brown.

Habitat

It is part of a species complex that encompasses several fungal species. The most common and closely related species are "Ganoderma lucidum" and "Ganoderma tsugae". There are multiple species of lingzhi encompassed within the "Ganoderma lucidum" species complex and mycologists continue researching the differences among species within this complex."Ganoderma lucidum" and its close relative, "Ganoderma tsugae", grow in the northern Eastern Hemlock forests. These two species of bracket fungus have a worldwide distribution in both tropical and temperate geographical regions, growing as a parasite or saprotroph on a wide variety of trees. Similar species of "Ganoderma" have been found growing in the Amazon.

In the wild, lingzhi grows at the base and stumps of deciduous trees, especially that of the maple. Only two or three out of 10,000 such aged trees will have lingzhi growth, and therefore it is extremely rare in its natural form. Today, lingzhi is effectively cultivated on hardwood logs or sawdust/woodchips.
