Affinities of the Boletus chromapes group to Royoungia and the description of two new genera, Harrya

Abstract. Harrya is described as a new genus of Boletaceae to accommodate Boletus chromapes, a pink-capped bolete with afinely scabrous stipe adornedwith pink scabers, a chromeyellowbase and a reddish-brown sporedeposit. Phylogenetic analyses of large-subunit rDNA and translation elongation factor 1a confirmedHarrya as a unique generic lineage with two species, one of which is newly described (H. atriceps). Some Chinese taxa were recently placed in a separate genus, Zangia, supported by both morphology andmolecular data. Multiple accessions fromQueensland, Australia, support the synonymy of at least three species in a separate Australian clade in the new genus, Australopilus. The truffle-like Royoungia is also supported as a separate lineage in this clade of boletes. Even though it lacks stipe characters, it possesses the deep, bright yellow to orange pigments in the peridium.Additional collections fromZambia andThailand represent independent lineages of uncertain phylogenetic placement in the Chromapes complex, but sampling is insufficient for formal description of ne
