Some earlier studies have included a number of Thai collections in ITS phylogenies, but these studies had insu cient sampling of closely related taxa to determine species limits 8, 9,10 .

Dry dipterocarp forests are among the most common habitat types in Thailand. Russulaceae are known as common ectomycorrhizal symbionts of Dipterocarpaceae trees in this type of habitat. The present study aims to identify collections of Russula subsection Amoeninae Buyck from dry dipterocarp forests in Thailand. A multi-locus phylogenetic analysis placed Thai Amoeninae collections in two novel lineages, and they are described here as Russula bellissima sp. nov. and R. luteonana sp. nov. The closest identified relatives of both species were sequestrate species suggesting that they may belong to drought-adapted lineages. The analysis of publicly available ITS sequences in R. subsect. Amoeninae did not confirm evidence of any of the new species occurring in other Asian regions, indicating that dry dipterocarp forests might harbor a novel community of ectomycorrhizal fungi. Macromorphological characters are variable and are not totally reliable for distinguishing the new species from other previously described Asian Amoeninae species. Both new species are defined by a combination of differentiated micromorphological characteristics in spore ornamentation, hymenial cystidia and hyphal terminations in the pileipellis. The new Amoeninae species may correspond to some Russula species collected for consumption in Thailand, and the detailed description of the new species can be used for better identification of edible species and food safety in the region.

“…In northern Thailand, where the relief of the country topography is more rugged, dry dipterocarp forests occur in lower elevation 19 . In the eastern part of the country they also occur in lowlands and low elevations but their occurrence is even more scattered probably due to intensive human land use 9,20 .…”

“…The plant family Dipterocarpaceae includes many species of large trees that are often dominant in the tropical and subtropical lowlands of Southeast Asia, where the species diversity of Dipterocarpaceae is highest ( Ashton 1982 , Hamilton et al 2019 ). Many Dipterocarpaceae are well known to be ECM, symbiotically associating with various ECM fungi, including mushroom-forming species ( Watling et al 2002 , Yuwa-Amornpitak et al 2006 , Brearley 2012 ). Several new genera and species of boletes have recently been documented from tropical dipterocarp forest ( Desjardin et al 2009 , Neves et al 2012 , Hosen et al 2013 , Halling et al 2014 , Raspé et al 2016 , Wu et al 2016 , Vadthanarat et al 2019 , Chuankid et al 2019 ).…”

Tylocinum Y.C. Li & Zhu L. Yang 2016 is a Boletaceae genus belonging in subfamily Leccinoideae. It was described in 2016 from China and, prior to this study, it contained only one species, T. griseolum Y.C. Li & Zhu L. Yang 2016. During our survey of Boletaceae from Thailand, we collected some specimens that could be identified as a Tylocinum species, different from T. griseolum. The bolete specimens, collected in forests dominated by Dipterocarpaceae and Fagaceae in northern Thailand, are described as Tylocinum brevisporum Raghoonundon & Raspé sp. nov. Macroscopic and microscopic descriptions with illustrations are provided, as well as a 3-gene phylogeny, which confirms the new taxon’s position in Tylocinum. Tylocinum brevisporum differs from the only other known Tylocinum species (T. griseolum) by its brownish-grey colour, greyish-orange to brownish-orange colour change in the hymenophore when bruised, smaller pores (≤ 0.5 mm), longer tubes (up to 6 mm long), shorter and narrower basidiospores, longer and broader basidia and longer pleurocystidia relative to cheilocystidia. T. brevisporum is the second species from the genus Tylocinum and the only one to be found outside China thus far.
