    Boletellus and Heimioporus, two genera of Boletaceae with ornamented basidiospores, are shown to be distinct genera on the basis of phylogenetic analyses of nuclear ribosomal large-subunit and translation elongation-factor 1α DNA sequences. Comparison of spore ornamentation type-longitudinally ribbed in Boletellus v. punctate, alveolate-reticulate in Heimioporus-are further evidence for distinction. Analyses of multiple accessions from the Americas, Asia and Australia support the monophyly of Heimioporus and a 'core Boletellus' clade, containing the type species, B. ananas (M.A.Curt.) Murrill, and approximately seven additional species. Tests of alternative phylogenetic topologies could not reject monophyly of a more inclusive group containing the core Boletellus clade and six other species. Heimioporus australis Fechner & Halling, H. cooloolae Fechner & Halling, Boletellus deceptivus Halling & Fechner, B. reminiscens Halling & Fechner and B. sinapipes Fechner, K.Syme, R.Rob. & Halling are described as new species. Phylogenetic analyses also support the following new combinations: Aureoboletus projectellus (Murrill) Halling, A. mirabilis (Murrill) Halling, Hemileccinum subglabripes (Peck) Halling and the new name, Xerocomus tenax Nuhn & Halling.

    Harrya is described as a new genus of Boletaceae to accommodate Boletus chromapes, a pink-capped bolete with a finely scabrous stipe adorned with pink scabers, a chrome yellow base and a reddish-brown spore deposit. Phylogenetic analyses of large-subunit rDNA and translation elongation factor 1 confirmed Harrya 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 and molecular data. Multiple accessions from Queensland, 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 from Zambia and Thailand represent independent lineages of uncertain phylogenetic placement in the Chromapes complex, but sampling is insufficient for formal description of new species. Specimens from Java referable to Tylopilus pernanus appear to be a sister group of the Harrya lineage. © 2012 CSIRO.

    The phylogeny of Phylloporus (Boletaceae) has not been well studied, and the taxonomic relationships of this genus have varied considerably among authors. The following study presents phylogenetic relationships of Phylloporus based on two nuclear ribosomal DNA regions, ITS and LSU. The ITS dataset includes 39 collections and the LSU dataset contains 50 collections of Phylloporus. A combined analysis of both genes did not resolve the deeper nodes in the phylogeny, but the results suggest that Phylloporus is monophyletic and a sister group of the Xerocomus subtomentosus group. The lamellate hymenophore configuration is a synapomorphy that distinguishes Phylloporus from the other genera in the family. The placement of a lamellate genus within Boletaceae suggests that hymenophore evolution is not well understood in the family. This is the first phylogeny of Phylloporus and includes 20 species from different geographic regions. Six taxa of Phylloporus from the Old World are here presented. Phylloporus cyanescens is a new combination for an Australasian taxon formerly named as a variety of P. bellus (Massee) Corner. Phylloporus pumilus is described from Indonesia, and 4 species are described from Thailand: P. castanopsidis, P. dimorphus, P. infuscatus, and P. rubiginosus. © The Mushroom Research Foundation 2012.

    Sutorius: A new genus for Boletus eximius

    Sutorius is described as a new genus of Boletaceae to accommodate Boletus robustus originally named illegitimately by C.C. Frost from eastern North America. The legitimate name, Boletus eximius, provided by C.H. Peck, has been used since for a dark purple to chocolate brown bolete with finely scaly stipe and reddish brown spore deposit. This iconic taxon has been documented on five continents. Despite the straightforward species identification from morphology, the interpretation of stipe macromorphology and spore color has led to equivocal generic placement. Phylogenetic analyses of genes encoding large subunit rRNA and translation elongation factor 1a confirm Sutorius as a unique generic lineage in the Boletaceae. Two species are recognized based on multiple accessions: S. eximius, represented by collections from North America, Costa Rica, Guyana, Indonesia and Japan (molecular data are lacking for only the Guyanan and Japanese material); and S. australiensis, represented by material from Queensland, Australia. Additional collections from Zambia and Thailand represent independent lineages, but sampling is insufficient to describe new species for these entities. © 2012 by The Mycological Society of America.
