During taxonomic revision of genus Octaviania in Japan we examined herbarium and fresh specimens of O. columellifera and O. asterosperma sensu S. Yoshimi & Y. Doi With morphological and molecular techniques. These two species were identical in both macro- and micromorphological characters and were clearly different from the generally known O. asterosperma. The identity of the two species and their distinctness from O. asterosperma was further Supported by both nuclear large subunit and ITS rDNA phylogeny. The Molecular analyses also revealed that O. columellifera shares its lineage with the boletoid mushroom-forming Xerocomus chrysenteron complex and that it does not form a monophyletic clade with other Octaviania species. Our morphological reevaluation, including transmission electron microscopic observation of basidiospores, clarified the taxonomic boundary between O. columellifera and other Japanese Octaviania species. Accordingly we propose a new genus, Heliogaster, for O. columellifera with designation of the lectotype. We discuss phylogenetic relationships with Octaviania sensu stricto species and the closely related boletoid (pileate-stipitate) fungi, generic characters of Heliogaster and intraspecific phylogeny.
