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, Butyriboletushuangnianlaii, Lanmaoamacrocarpa, Neoboletusmultipunctatus, and Sutoriussubrufus, are new to science. Chalciporusradiatus and Caloboletusxiangtoushanensis are redescribed. Caloboletusguanyui is proposed to replace Boletusquercinus Hongo, an illegitimate later homonym. The recently described Tylopiluscallainus is synonymized with the Japanese Boletusvirescens, and the new combination T.virescens (Har. Takah. & Taneyama) N.K. Zeng et al. is proposed. Moreover, Neoboletus 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 Sutorius are recombined into Neoboletus: N.ferrugineus (G. Wu et al.) N.K. Zeng et al., N.flavidus (G. Wu & Zhu L. Yang) N.K. Zeng et al., N.hainanensis (T.H. Li & M. Zang) N.K. Zeng et al., N.obscureumbrinus (Hongo) N.K. Zeng et al., N.rubriporus (G. Wu & Zhu L. Yang) N.K. Zeng et al., N.sanguineoides (G. Wu & Zhu L. Yang) N.K. Zeng et al. , N.sanguineus (G. Wu & Zhu L. Yang) N.K. Zeng et al., and N.tomentulosus (M. Zang et al.) N.K. Zeng et al.

Cacaoporus, a new Boletaceae genus, with two new species from Thailand

“…Moreover, the Neoboletus clade was not supported either. Later, Chai et al (2019) treated the two genera as different genetic lineages based on morphology and phylogeny (28S+ITS+ tef 1+ rpb 2), in which B.obscureumbrinus clustered with the other Neoboletus species in a well-supported clade. Our phylogenetic analyses, based on a different set of genes ( atp 6+ tef 1+ rpb 2+ cox 3), confirm the separation of the two genera Neoboletus and Sutorius .…”

An Unexpectedly High Number of New Sutorius (Boletaceae) Species From Northern and Northeastern Thailand

“…Moreover, the phylogeny in that study suggested an additional five undescribed Sutorius species clustering in 10 independent linages (three described species included). That inference also indicated the exemplars identified as S. eximius, originating from several different countries (China, Costa Rica, Indonesia, and United States), were in a polytomic lineage (Chai et al, 2019). So far, the distribution of Sutorius has been recorded to occur in several regions including the Americas, Africa, Asia, and Australia (Singer, 1947;Smith and Thiers, 1971;Fulgenzi et al, 2007;Chandrasrikul et al, 2011;Halling et al, 2012;Chai et al, 2019).…”

“…In 2016, Wu et al, recombined S. rubriporus G. Wu and Zhu L. Yang). Later, Chai et al (2019) restudied the phylogenetic relationships of several Boletaceae specimens from subtropical and tropical China, reinstated the genus Neoboletus Gelardi, Simonini and Vizzini and recombined all Sutorius species described in Wu et al (2016) to be into this latter. Chai et al (2019) also newly described a third species of Sutorius, Sutorius subrufus N.K.…”

At present, only three species have been placed in the genus (Halling et al, 2012;Chai et al, 2019).…”

Longistriata flava (Boletaceae, Basidiomycota) – a new monotypic sequestrate genus and species from Brazilian Atlantic Forest

“…Caff. in Patagonian Nothofagus forests (Nouhra et al 2012). Recently, undescribed taxa of sequestrate Boletaceae were cited from tropical forests in Guyana (Henkel et al 2012;Smith et al 2013) (Castellano et al 2016;Chai et al 2019).…”
