Ganoderma microsporum was first discovered in Taipei, Taiwan by R.-S. Hseu in 1982, and published in the scientific journal Mycotaxon in 1989. Research 
Compounds discovered in Ganoderma include polysaccharides, triterpenoids, nucleic acids and fungal immunomodulatory proteins or FIPs. According to the NIH PubMed database on the physiological activities of G. microsporum, primarily from the FIP found in G. microsporum (FIP-gmi or GMI), currently known physiological activities include effects on the central nervous system and the respiratory system.
