No exact current species can be attached to these ancient lingzhi for certain, but according to Dai et al. There, a number of different lingzhi-like mushrooms were used for different purposes and defined by color. One of the sources employed to solved the task of identifying the traditional lingzhi mushroom is the 16th century Chinese herbal compendium, the Bencao Gangmu (1578). This leads to a lot of confusion in culture, as well as in the scientific community, when trying to codify and describe its medicinal uses. As the lingzhi fungus is strongly rooted into culture, the old name persists, even though it is well established that G. sichuanense and G. lucidum are distinct species. Early records of chinese Genoderma populations identified them as G. lucidum, but it was later established that Asian populations are distinct from European both morphologically and phylogenetically. Ganoderma lucidum - a type species of Genoderma described by Karst (1881) based on the European population.(2023) showed that it is the same species as G. (2012) as a novel species that is also the best fit for the traditional definitions of the lingzhi mushroom. Ganoderma lingzhi - described by Cao et al.Ganoderma sichuanense - the current name, described by Zhao and Zhang (1983).Under the scientific literature, the lingzhi mushroom is ambiguously referred to as: It is also likely that a few different common species were considered interchangeable. However, as of 2023 there is an ongoing debate on which one of the described Ganoderma species is the lingzhi mushroom. Lingzhi, also known as reishi from its Japanese pronunciation, is the ancient "mushroom of immortality", revered for over 2,000 years (with some evidence suggesting use in Neolithic China 6,800 years ago). Lingzhi may be cultivated on hardwood logs, sawdust, or woodchips. Only two or three out of 10,000 such aged trees will have lingzhi growth, and therefore its wild form is rare. In nature, it grows at the base and stumps of deciduous trees, especially that of the maple.

There is insufficient evidence to indicate that consuming lingzhi mushrooms or their extracts has any effect on human health or diseases. The lingzhi mushroom is used in traditional Chinese medicine. It lacks gills on its underside, and instead releases its spores via fine pores (80–120 μm) in yellow colors. When fresh, the lingzhi is soft, cork-like, and flat. Its reddish brown varnished kidney-shaped cap with bands and peripherally inserted stem gives it a distinct fan-like appearance. Lingzhi, Ganoderma sichuanense, also known as reishi or Ganoderma lingzhi is a polypore fungus ("bracket fungus") native to East Asia belonging to the genus Ganoderma.
