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