Some glutinously violet Cortinarius specimens resembling C. In this study, we have conducted taxonomic and phylogenetic studies of Cortinairus in China. Teng, 1963 Yuan & Sun, 1995 Shao & Xiang, 1997 Li & Azbukina, 2011 Xie, 2018 Wang et al., 2020), but the occurrence of species in China is controversial due to the lack of voucher specimens. from Heilongjiang, Jilin, Liaoning and Inner Mongolia, were reported ( e.g. from Heilongjiang, Jilin, Qinghai, Sichuan and Yunnan, C. In China, over 237 Cortinairus species, including several new species, have been described from China ( Wei & Yao, 2013 Xie et al., 2019 Xie et al., 2020 Xie et al., 2021 Yuan et al., 2020 Luo & Bau, 2021). Delibuti, but the phylogenetic studies showed that the species diversity of this section is still unrevealed ( Harrower et al., 2011 Garnica et al., 2016 Soop et al., 2019). In the past, numeral species were assigned to section Delibuti ( Fries, 1838 Earle, 1902 Bidaud, Moënne-Loccoz & Reumaux, 1992 Soop, 2013 Soop, 2014) however, most species have been confirmed not to belong to this section ( Orton, 1955 Consiglio, 2012 Dima et al., 2016 Soop et al., 2019). Anomali Konrad & Maubl., together with support in the phylogenetic analyses. Delibuti among anomaloid sections, not in myxacioid sections based on the shared characters of sect. Phlegmacium (Fr.) Trog ( Bidaud, Moënne-Loccoz & Reumaux, 1992 Bidaud, Moënne-Loccoz & Reumaux, 1994). Section Delibuti was also considered to belong to subg. Delibuti species can easily be distinguished by the anomaloid appearances, mild taste and subglobose basidiospores from other myxacioid species ( Orton, 1955 Soop, 2014). Myxacium (Fr.) Trog ( Trog, 1844 Earle, 1902 Orton, 1955 Brandrud et al., 1989 Consiglio, Antonini & Antonini, 2003). with characteristics of viscid pileus and stipe, have usually been considered as a section in subg. (2019) presented a section-based taxonomy of Cortinarius based on four loci of a large global sampling.Ĭortinarius sect. (2005) proposed natural classification system in Cortinarius involving the taxonomic rearrangement of the species into eight informal clades. Fries, 1838 Trog, 1844 Orton, 1955 Bidaud, Moënne-Loccoz & Reumaux, 1994 Garnica, Weiß & Oberwinkler, 2003 Garnica et al., 2005 Harrower et al., 2011 Stensrud et al., 2014 Niskanen et al., 2015 Garnica et al., 2016 Soop et al., 2019). Several systems of subgenus and sections in Cortinarius are erected based on the macromorphology of geographically limited samplings, but these are not supported by phylogenetic studies ( e.g.
Most of Cortinarius species were originally discovered from Europe and America but rarely in Asia and Africa ( Horak, 1983 Garrido-Benavent et al., 2020 Xie et al., 2020). Even though it is the largest genus among macrofungi, its species diversity is still unclear. The genus is distributed worldwide with nearly 3,000 species ( Niskanen et al., 2018 Ammirati et al., 2021 Bidaud et al., 2021). PeerJ 9: e11982 Ĭortinarius (Pers.) Gray is an ectomycorrhizal fungal genus, associated with a wide host range of plants, such as Betulaceae, Caesalpiniaceae, Cistaceae, Dipterocarpaceae, Fagaceae, Myrtaceae, Pinaceae, Rhamnaceae, Rosaceae, Salicaceae and some herbaceous plants ( Frøslev, Brandrud & Jeppesen, 2006 Niskanen, 2008).
