Antrodiella was established in 1980 to embrace the Polyporus semisupinus Berk. & M.A. Curtis complex (Ryvarden and Johansen 1980). It was characterized by resupinate, effused-reflexed to pileate basidiocarps with elastic consistency when fresh and dense and hard when dry, small pores, light-colored pore surface, a dimitic to trimitic hyphal structure, small ellipsoid to cylindrical basdiospores and producing a white rot (Núñez and Ryvarden 2001; Dai 2004). More than 50 species have been described worldwide (Yuan 2014). The circumscription of Antrodiella has been expanded greatly, but the cyanophilic reaction of the skeletal hyphae was always considered an important and consistent character. Recently, DNA-based molecular phylogenetic studies have been revealed the non-monophyletic background of Antrodiella, and showed very complicated relationships among the genera of Antrodiella, Flaviporus, Junghuhnia and Steccherinum (Vampola and Vlasák 2011; Miettinen et al. 2012; Yuan 2013, 2014).
