Bjerkandera carnegieae comb. nov. ( Phanerochaetaceae , Polyporales ) a wood-decay polypore of cactus

[摘要] Poria carnegieae was described from Arizona growing on the woody ribs of the saguaro cactus, Carnegiea gigantea, and was transferred to Ceriporiopsis due to morphological evidence. Posterior phylogenetic studies showed a relationship of Poria carnegieae with Bjerkandera. New sequence data and morphologic evidence are presented to support the transfer of Ceriporiopsis carnegieae to Bjerkandera.
