Abstract
Eleven taxa of
Lopharia s.s., Dendrodontia, Dentocorticium and
Fuscocerrena in Polyporales are included in the phylogenetic analyses of nuc rDNA ITS1-5.8S-ITS2 (ITS), D1-D2 domains of nuc 28S rDNA (28S) and RNA polymerase II second-largest subunit (
rpb2) sequences. New species
Lopharia resupinata and
L. sinensis are described and illustrated.
Lopharia resupinata, from south-eastern China, is closely related to
L. ayresii, and
L. sinensis, from northern China, is related to
L. cinerascens and
L. mirabilis.
Lopharia mirabilis specimens from temperate to tropical areas with varied hymenophore configurations all cluster together in a fully supported clade.
Dendrodontia and
Fuscocerrena are shown to be synonyms of
Dentocorticium, which is phylogenetically related to
Lopharia. Four new combinations,
Dentocorticium bicolor, D. hyphopaxillosum, D. portoricense and
D. taiwanianum, are proposed. Revised generic descriptions of
Lopharia and
Dentocorticium are provided with keys to the six accepted species in each genus. A list of all names in
Lopharia and
Dentocorticium are presented with their current taxonomic status. Type specimens of
Dentocorticium brasiliense and
D. irregulare were examined and determined to be later synonyms of
Punctularia subhepatica and
Diplomitoporus daedaleiformis, respectively.
