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.
