Two new Erythrophylloporus species (Boletaceae) from Thailand, with two new combinations of American species

Abstract

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.

New species of Retiboletus (Boletales, Boletaceae) from China based on morphological and molecular data

“…Protocols for DNA extraction, PCR, sequencing and sequence alignment followed those in Vadthanarat et al (2019), Gelardi et al (2019), Zhang et al (2019) and references therein. The primer pair used for amplifying the nrLSU region was LROR and LR5 (Vilgalys and Hester 1990).…”

New scientific discoveries: Plants and fungi

“…Fifty‐one new species were described from the family containing the milkcaps ( Lactarius and Lactifluus (e.g., Delgat et al, 2019, Wang et al, 2019)) and the brittlecaps ( Russula (e.g., Adamčik et al, 2019)), an enigmatic group of over 2,000 species of mushrooms that form mycorrhizal associations with vascular plants ranging from giant Lithocarpus trees in southeast Asia to dwarf willows ( Salix arctica ) in the Arctic. Another group that saw a surge in new species descriptions were the boletes (Boletaceae): 37 new species described across 15 genera (e.g., Vadthanarat et al, 2019; Zhang , Li, Wang, & Zeng, 2019). Of particular note are the latest results from a long‐term, ongoing study of the colloquial “Old Man in the Woods” bolete ( Strobilomyces ) which introduced eight new species to this genus (Han et al, 2019).…”

Continental‐scale metagenomics, BLAST searches, and herbarium specimens: The Australian Microbiome Initiative and the National Herbarium of Victoria

“…Although the study of fungal diversity has been biased toward Northern Hemisphere temperate ecosystems, there have been major efforts to reconcile the gap in knowledge regarding tropical and Southern Hemisphere fungi, with major foci of activity in the eastern paleotropics (Luo et al, 2016; Vadthanarat et al, 2018, 2019; Sukarno et al, 2019), Central and South America (Kuhar et al, 2017; Accioly et al, 2018; Kaishian and Weir, 2018; Ovrebo et al, 2019), Africa (Castellano et al, 2016; Buyck et al, 2018, 2019; Jami et al, 2018), and Australia (Midgley et al, 2018; Davoodian et al, 2019; Ji et al, 2019; Khmelnitsky et al, 2019).…”
