| 摘要 | Purpose: The polypore genus Ceriporia belongs to Polyporales of Basidiomycota and encompasses around 80 species which are saprotrophs or endophytes in forest ecosystems. Despite its high species diversity, few Ceriporia species have been incorporated into phylogenetic studies. To better understand the limits of Ceriporia and its phylogenetic relationship with other related taxa, we expand the molecular and taxonomic sampling, including new sequences, and new samples from East Asia.
Methods: We used morphology and multi-marker phylogenetic analyses based on sequences of the nuc rDNA ITS1-5.8S-ITS2 (ITS), D1-D2 domains of nuc 28S rDNA (28S), and RNA polymerase II largest subunit (rpb1). Two datasets were used: (i) The ITS+28S+rpb1 dataset was used to investigate the systematic positions of Ceriporia species within families of Polyporaels; (ii) The ITS+28S dataset, with a larger sampling of species and specimens, was used to infer interspecific relationships and taxonomy in clades I and II recovered in the 3-marker analyses.
Results and conclusions: Our results show that Ceriporia is polyphyletic, and distribute across clades I-III in Irpicaceae and a lineage (C. alachuana) in Meruliaceae. In clade I, some species previously considered classified in Ceriporia, are now recovered in Meruliopsis, resulting in four new combinations: M. albomellea, M. crassitunicata, M. nanlingensis, and M. pseudocystidiata. Clade II, having dominant Ceriporia species, represents Ceriporia sensu stricto. Clade III includes C. cystidiata and C. sulphuricolor. Three species are new to science: C. arbuscula and M. parvispora from Taiwan; M. leptocystidiata from North East Asia. Three species are new records: C. mellita and M. nanlingensis from Japan and Taiwan; M. taxicola from Taiwan. |
