Abstract: | Three species of Hyphodontia (Schizoporaceae) with poroid or raduloid hymenial surface are described as new to science. Hyphodontia chinensis sp. nov. was found in southwest and northeast China, having raduloid hymenophore, ventricose to subulate cystidia, and slightly thickened-walled, ellipsoid basidiospores; H. reticulata sp. nov. was found in central Japan and northern Taiwan, having poroid hymenophore, projecting peg-like structures, and encrusted cystidia; H. subtropica sp. nov. was collected from China (Yunnan province) and northern Vietnam, having poroid hymenophore, slightly apically swollen cystidioles, and pseudodimitic hyphal system. Both maximum parsimony and Bayesian methods were used to construct the phylogenetic trees based on ITS (internal transcribed spacer) sequences. The independent status of each proposed new species is based on morphological study, further confirmed by ITS-based phylogenetic analysis. The recently presented H. dimitica is found to be conspecific with H. nongravis, based on morphological and molecular evidences. |
