Notes.

Ceriporiopsis pseudoplacenta Vlasák & Ryvarden and C. alboaurantia were recently described from USA ( Vlasák et al. 2012) and China ( Cui and Zhao 2014), respectively. However, Vampola and Vlasák (2021) recombined C. pseudoplacenta into Aurantiporus following morphological analyses, and they considered Aurantiporus priscus Niemelä et al. described from Europe two months later ( Niemelä et al. 2012) as a taxonomic synonym of A. pseudoplacentus (Vlasák & Ryvarden) J. Vlasák & P. Vampola. Our updated phylogeny with enhanced taxon sampling also indicates that both species are nested within the Aurantiporus s. str. clade (Fig. 1 ), but it is not sure that they are conspecific. All these species resemble the type species of Aurantiporus by sharing dense agglutinated tubes, shrinking and darkening upon drying, and a monomitic hyphal system with ellipsoid, smooth basidiospores. Hence, the above combination is proposed.

Phlebicolorata C. L. Zhao , typified with P. brevispora (Nakasone) C. L. Zhao , was established to include the generic type and A. pseudoplacentus , C. alboaurantia , and A. roseus (C. L. Zhao & Y. C. Dai) Zmitr. ( Zhao et al. 2023). However, the latter three species are nested in the Aurantiporus s. str. clade in our phylogeny (Fig. 1 ). Similar results were obtained by Liu et al. (2022).
