Taiwanofungus Sheng H. Wu, Z.H. Yu, Y.C. Dai & C.H. Su is proposed as a new genus of lignicolous polypore, and Ganoderma comphoratum M. Zang & C.H. Su is designated as its generic type. New combinations for two species of Taiwanofungus are presented: T. camphoratus (M. Zang & C.H. Su) Sheng H. Wu, Z.H. Yu, Y.C. Dai & C.H. Su, and T. salmoneus (T.T. Chang & W.N. Chou) Sheng H. Wu, Z.H. Yu, Y.C. Dai & C.H. Su. Taiwanofungus camphoratus is known in Taiwan as ”niu-chang-chih”. Taiwanofungus shares many common charaters with Antrodia and Antrodiella. Phylogenetic analysis based on sequence data derived from LSU rDNA indicates that Taiwanofungus camphoratus neither clusters with Antrodia, nor with Antrodiella. Taiwanofungus camphoratus is known only occurring in Taiwan and on trunk of Cinnamomum kanehirai Hay. This fungus is well known by its medicinal uses and high economic value. Taiwanofungus camphoratus was first named Ganoderma comphoratum in 1990. Antrodia cinnamomea T.T. Chang & W.N. Chou was presented for the same species in 1995. Antrodia camphorata (Zang & Su) Sheng H. Wu, Ryvarden & T.T. Chang, new combination proposed in 1997 based on Ganoderma comphoratum, has been widely applied to this fingus.
