“…PCR conditions were the same as in Raspé et al (2016). Part of the mitochondrial gene cox 3 was amplified with the primers COX3M1-F and COX3M1-R (Vadthanarat et al 2019), using KAPA2G™ Robust HotStart polymerase (Kapa Biosystems, Wilmington, MA, USA) and the following PCR programme: 2 min 30 s at 95 °C; 35 cycles of 25 s at 95 °C, 30 s at 48 °C, 30 s at 72 °C; 3 min at 72 °C. PCR products were purified by adding 1 U of Exonuclease I and 0.5 U FastAP Alkaline Phosphatase (Thermo Scientific, St. Leon-Rot, Germany) and incubated at 37 °C for 1 h, followed by inactivation at 80 °C for 15 min.…”

Erythrophylloporus is a lamellate genus in the family Boletaceae that has been recently described from China based on E.cinnabarinus, the only known species. Typical characters of Erythrophylloporus are reddish-orange to yellowish-red basidiomata, including lamellae, bright yellow basal mycelium and smooth, broadly ellipsoid, ellipsoid to nearly ovoid basidiospores. During our survey on diversity of Boletaceae in Thailand, several yellowish-orange to reddish- or brownish-orange lamellate boletes were collected. Based on both morphological evidence and molecular analyses of a four-gene dataset (atp6, tef1, rpb2 and cox3), they were recognised as belonging in Erythrophylloporus and different from the already known species. Two new species, E.paucicarpus and E.suthepensis are therefore introduced from Thailand with detailed descriptions and illustrations. Moreover, two previously described Phylloporus species, P.aurantiacus and P.fagicola, were also revised and recombined in Erythrophylloporus. A key to all known Erythrophylloporus species is provided.

“…ITS-5.8 region of the nuclear ribosomal DNA was not sequenced because in Boletaceae, ITS commonly shows high levels of intraindividual polymorphisms for indels, thus mostly preventing straightforward phylogenetic analysis and moreover often making cloning necessary to obtain a sequence. The selected protein-coding genes have shown multiple times their usefulness for investigating phylogenetic relationships, at both infrageneric and suprageneric levels (e.g., Wu et al, 2016;Vadthanarat et al, 2019). For the amplification of atp6, ATP6-1M40F and ATP6-2M primers were used, with following the protocol and PCR program in Raspé et al (2016).…”

“…For ML, phylogenetic inference was performed using RAxML (Stamatakis, 2006) on the CIPRES web portal (RAxML-HPC2 on XSEDE; Miller et al, 2009), using the GTRCAT model with 25 categories. Three Butyriboletus species were used as outgroup based on the phylogeny in Vadthanarat et al (2019). Statistical support of clades was obtained with 1,000 rapid BS replicates.…”

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

Sutorius is a poroid genus in Boletaceae that typically has chocolate brown to reddish brown or purplish brown basidiomata with a finely scaly stipe and produces a reddish brown spore deposit. During the survey on diversity of boletes in Northern and Northeastern Thailand, several Sutorius collections were obtained. Combined evidence from morphology and phylogenetic analyses of a combined three-gene data set (atp6, tef1 and rpb2) of the Sutorius collections along with selected Boletaceae in the Pulveroboletus group indicated that Thai collections represent seven new Sutorius species. The analyses also indicated that Tylopilus maculatoides belongs in Sutorius. Therefore, the transfer of T. maculatoides to Sutorius is proposed. Full descriptions and illustrations of the seven new species and S. maculatoides are presented in this study. With the seven new species and the new combination, eight of the eleven described Sutorius species are known to occur in Northern and Northeastern Thailand, whereas only one species is known from each of two continents, the Americas and Australia.

The genus Hemileccinum belongs to the subfamily Xerocomoideae of the family Boletaceae. In this study, phylogenetic inferences of Hemileccinum based on sequences of a single-locus (ITS) and a multi-locus (nrLSU, tef1-α, rpb1, rpb2) were conducted. Four new species, namely H. abidum, H. brevisporum, H. ferrugineipes and H. parvum were delimited and proposed based on morphological and molecular evidence. Descriptions and line-drawings of them were presented, as well as their comparisons to allied taxa. Our study shed new light on the recognition of the genus. The pileipellis of the species in this genus should mostly be regarded as (sub)epithelium to hyphoepithelium, because the pileipellis of most studied species here is composed of short inflated cells in the inner layer (subpellis) and filamentous hyphae in outer layer (suprapellis). The basidiospores of the studied species, including the type species, H. impolitum, have a warty surface.
