New and noteworthy boletes from subtropical and tropical China

Abstract

The morphology, ecology, and phylogenetic relationships of specimens of the family Boletaceae from subtropical and tropical China were investigated. Four species, <i>Butyriboletushuangnianlaii</i>, <i>Lanmaoamacrocarpa</i>, <i>Neoboletusmultipunctatus</i>, and <i>Sutoriussubrufus</i>, are new to science. <i>Chalciporusradiatus</i> and <i>Caloboletusxiangtoushanensis</i> are redescribed. <i>Caloboletusguanyui</i> is proposed to replace <i>Boletusquercinus</i> Hongo, an illegitimate later homonym. The recently described <i>Tylopiluscallainus</i> is synonymized with the Japanese <i>Boletusvirescens</i>, and the new combination <i>T.virescens</i> (Har. Takah. & Taneyama) N.K. Zeng et al. is proposed. Moreover, <i>Neoboletus</i> is treated as an independent genus based on evidence from morphology and molecular phylogenetic data in the present study, and many previously described taxa of <i>Sutorius</i> are recombined into <i>Neoboletus</i>: <i>N.ferrugineus</i> (G. Wu et al.) N.K. Zeng et al., <i>N.flavidus</i> (G. Wu & Zhu L. Yang) N.K. Zeng et al., <i>N.hainanensis</i> (T.H. Li & M. Zang) N.K. Zeng et al., <i>N.obscureumbrinus</i> (Hongo) N.K. Zeng et al., <i>N.rubriporus</i> (G. Wu & Zhu L. Yang) N.K. Zeng et al., <i>N.sanguineoides</i> (G. Wu & Zhu L. Yang) N.K. Zeng et al. , <i>N.sanguineus</i> (G. Wu & Zhu L. Yang) N.K. Zeng et al., and <i>N.tomentulosus</i> (M. Zang et al.) N.K. Zeng et al.
