Antrodia is considered one of the larger genera of brown-rot fungi with a total of approximately 60 species (ca. 30 from Europe, 13 from Asia, 11 from North America, four from South America and two from Africa). Molecular phylogenies have demonstrated that Antrodia is not monophyletic and Antrodia s.l. has been divided into three genera: Antrodia s.s., Amyloporia and Fibroporia. Preliminary phylogenetic studies (as part of the PolyPEET project) using molecular data from two nuclear ribosomal DNA regions (LSU and ITS) confirmed that Fibroporia most likely represents an independent genus, but the segregation of Amyloporia spp. from Antrodia s.s. was not strongly supported. In these preliminary studies, 33 species of Antrodia/Amyloporia and 7 of Fibroporia were included. To better resolve these groups we are currently generating data from protein-coding genes (RPB1, TEF1-alpha) to assess the relationships among Antrodia species and determine the species delimitation within the genus. Results of the ongoing research will be presented.
