“…Habitat: Solitary to gregarious on the ground in forests with Lithocarpus spp., Castanopsis spp., Shorea spp., and Dipterocarpus spp. Note: Macro-and micro-morphology of R. nigrogriseus speci-mens from Thailand match the description of the specimens from China (holotype, FHMU 2800), except for the pileipellis structure, which was reported to be a subcutis by Zeng et al (2018), whereas we observed a trichodermium. This discrepancy may be due to observations being made on basidiomes at different stages of development.…”

“…Recently, Retiboletus collections from China were studied, and their molecular phylogenetic analyses confirmed the monophyly of Retiboletus (Wu et al, 2014;Zeng, Liang, Wu, Li, & Yang, 2016). To date, nine Retiboletus species have been reported from China (Wu et al, 2016;Zeng et al, 2016Zeng et al, , 2018Liu, Li, & Bau, 2020 For several years, we have collected Boletaceae in northern Thailand, where fungal diversity is high (Hyde et al, 2018). In this study, three Retiboletus species from northern Thailand are investigated based on both morphology and phylogenetic analyses.…”

Morphological characters and multi-gene phylogenetic analyses were used to identify Retiboletus specimens collected in northern Thailand. Retiboletus brevibasidiatus is described as new to science, whereas R. fuscus and R. nigrogriseus are reported for the first time from Thailand. Retiboletus brevibasidiatus produces medium-sized basidiomes, with a dark blonde to clay pileus and densely reticulate stipe mostly on the upper part with pale yellow to chrome yellow basal mycelium. It is difficult to separate R. brevibasidiatus from other closely related species on the basis of macroscopic characters. However, the new species can be distinguished by microscopic characters, mostly the shorter basidia. The macro-and micro-morphology of the R. fuscus and R. nigrogriseus collections from Thailand fit well with the previous descriptions of materials from China and Japan. Detailed descriptions, molecular phylogeny, and illustrations of the three species are provided.

“…Subtropical and tropical China is believed to be a biodiversity hotspot. Mycologists have paid much attention to boletes of the region in the past decade, and many taxa have been discovered (Bi et al 1997; Zeng and Yang 2011; Zeng et al 2012, 2013, 2014a, b, 2015a, b, 2016, 2017, 2018; Zang 2013; Liang et al2016, 2017, 2018; Chai et al 2018; Xue et al 2018). Among of them, many have been found to be as North American or European species (Bi et al 1997; Zang 2013), and recent studies have shown that species shared between subtropical/tropical China and North America/Europe are rare but that there are many common species between Japan and subtropical/tropical China (Zeng et al 2013, 2016, 2017).…”

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.

“…The separation of Retiboletus from Boletus s. str. and its establishment at the generic rank is strongly supported (Wu et al 2016;Zeng et al 2016Zeng et al , 2018Badou et al 2018). So far thirteen species of this genus have been described from North/Central America and East Asia, seven out of which have been reported from China (Binder and Bresinsky 2002;Zeng et al 2016Zeng et al , 2018.…”

Species of the genus Retiboletus in China were investigated based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU) and the translation elongation factor 1-α gene (TEF1-α). Nine species were recovered from China, including two new and seven known species. The new species, namely Retiboletus ater and R. sinogriseus, from southwestern and northeastern China respectively, are documented and illustrated in this paper. Retiboletus ater is morphologically characterized by its black to grayish black pileus, white to grayish hymenophore, black to blackish stipe and white to grayish white context. Retiboletus sinogriseus is morphologically characterized by its brown to grayish-brown pileus, yellow to grayish-yellow hymenophore, pale yellow to brownish stipe and yellow to brownish-yellow context. Descriptions and line drawings of these two novel species and their comparisons with allied taxa are presented.
