Scientists have officially distinguished Ganoderma lucidum and Ganoderma lingzhi as separate mushroom species, resolving long-standing confusion caused by mislabeled specimens. The findings follow an extensive DNA analysis conducted by the Royal Botanic Gardens, Kew.
Why it matters
The study corrects a scientific error originating from the 18th century, when the loss of the original type specimen led researchers to mistakenly group similar-looking fungi together. This taxonomic clarification is essential for accurate botanical classification and future genetic research.
DNA analysis confirmed that Ganoderma lucidum and Ganoderma lingzhi diverged on separate evolutionary paths 16 million years ago. Researchers used these genetic tools to re-verify specimens against the 18th-century description by William Curtis.
The players
Royal Botanic Gardens, Kew
This globally renowned institution, based in London, serves as a center for plant and fungal research and houses extensive botanical collections.
Dr. Viktor Papp
He is a researcher who identified the critical, mislabeled 18th-century fungal specimen that enabled the recent taxonomic breakthrough.
William Curtis
He was an 18th-century botanist who first detailed the species Ganoderma lucidum in 1781.
The details
Dr. Viktor Papp led the identification effort by locating a mislabeled 18th-century mushroom specimen from a hazel tree held at the Kew Fungarium. By comparing the DNA of this rediscovered sample against modern genetic data, the team successfully untangled the confused history of these fungi.
Timeline
16 million years ago: The two species diverged on separate evolutionary paths.
1781: William Curtis provided the original description of Ganoderma lucidum.
2025: Dr. Viktor Papp uncovered a mislabeled mushroom specimen.
September 2026: Researchers formally recognized the species Ganoderma sinolucidum.
October 27, 2026: The research findings were published in the journal Plants, People, Planet.
The Big Picture
This study marks a significant paradigm shift by correcting centuries of misidentification in fungal taxonomy. It follows a pattern of taxonomic revision led by the Royal Botanic Gardens, Kew fungal classification standards.
This research provides a more precise framework for botanists and medical researchers who rely on accurate species identification for the study of fungal properties. It ensures that future scientific literature and databases are built on verified, consistent genetic data.
The takeaway
Taxonomic accuracy is vital for maintaining the integrity of biological databases and scientific research. Researchers can ensure more reliable findings by prioritizing the verification of historical type specimens against modern genetic profiles.
