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.} }
