Notes – Skeletocutis Kotl. & Pouzar was established in 1958 and its type species is S. amorpha (Fr.) Kotl. & Pouzar (Kotlába and Pouzar 1958). The genus has resupinate to pileate basidiocarps, encrusted generative hyphae covered by fine crystals and tiny basidiospores, these are the most important characteristics of the genus. In addition, species in Skeletocutis cause white rot disease (Niemelä 1998). Species in this genus have wide distribution in the world, but the majority of the known species so far are found in the Northern Hemisphere (Gilbertson and Ryvarden 1986; Núñez and Ryvarden 2001; Ryvarden and Melo 2014). There are more than 60 taxa recorded in Skeletocutis and 25 of them occur in China (Cui and Dai 2008; Dai 2012; Zhou and Qin 2012; Bian et al. 2016; Fan et al. 2017; Du and Dai 2020).
Recently, taxonomic and phylogenetic studies of polypore fungi from China have been extensively carried out, and many new genera or new species have been found (Zhao et al. 2015; Han et al. 2016; Chen and Cui 2017; Chen et al. 2017a, b; Song and Cui 2017; Zhou and Cui 2017; Xing et al. 2018; Cui et al. 2019; Shen et al. 2019; Wu et al. 2019; Zhu et al. 2019; Sun et al. 2020a, b; Liu et al. 2021a, b), however, only very few studies have been focused on Skeletocutis of the Incrustoporiaceae. In this study, two new species of Skeletocutis are described from China based on morphological characteristics and phylogenetic analyses inferred from ITS+nLSU sequences.
