“…The type species, O. asterosperma Vitt., is reported worldwide (e.g. Vittadini 1831, Massee 1889, Coker and Couch 1928, Zeller and Dodge 1936, Hawker 1954, Moreno et al 1991, Cázares et al 1992, Montecchi and Sarasini 2000. From Japan three Octaviania species have been reported, O. columellifera Kobayasi (Kobayasi 1937), O. asterosperma (Kobayasi et al 1987, Yoshimi andDoi 1989) and O. tuberculata Hesse (Yoshimi and Doi 1989).…”

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.

“…The well-known type species, O. asterosperma Vittad. has been reported worldwide (e.g., Vittadini 1831, Massee 1889, Coker & Couch 1928, Zeller & Dodge 1936, Hawker 1954, Moreno et al 1991, Cázares et al 1992, Tao et al 1998, Montecchi & Sarasini 2000), but morphological diversity among collections from different regions indicates that this may not be a truly cosmopolitan species. Intensive studies in one region using both morphological and molecular techniques may reveal greater species diversity of the genus and provide a more precise understanding of its biogeography.…”

The sequestrate fungi of Japan, including truffle and truffle-like fungi, have not been well characterized but are potentially diverse. We investigated the diversity and phylogeny of Japanese Octaviania specimens using a multifaceted approach including scanning and transmission electron microscopy as well as analysis of nuclear ribosomal DNA (ITS and LSU) and EF-1α (tef1) sequences. Phylogenetic analyses indicate that the genus Octaviania is divided into three major clades, and that there are at least 12 species-level lineages in Japan. Accordingly, we describe two new subgenera, Parcaea and Fulvoglobus, and eleven new species. Subgenus Parcaea accommodates four highly divergent, but macromorphologically almost indiscernible cryptic species. We discuss not only the diversity and species delimitation within the genus Octaviania but also the phylogeography of the Japanese taxa and their relatives.

Antecedentes y Objetivos: En México se han reportado 42 especies de ascomicetos con hábito hipogeo; son pocas considerando el conocimiento de otros grupos de hongos. El objetivo de este trabajo fue incrementar el conocimiento sobre la diversidad y distribución de especies de hongos hipogeos para México.Métodos: Se realizaron recolectas en diversos tipos de vegetación del Sistema Volcánico Transversal en la porción occidental perteneciente al estado de Michoacán. El material se fotografió y describió siguiendo los protocolos para el grupo.Resultados clave: Se presentan la descripción y discusión de seis especies de ascomicetos con hábito hipogeo, Elaphomyces appalachiensis, Genea mexicana, Genabea cerebriformis, Hydnobolites cerebriformis, Tuber pseudoseparans y T. tequilanum.Conclusiones: Los registros representan nuevas localidades para el país y primeras citas para la micobiota del estado de Michoacán. Se incrementa la distribución de Elaphomyces appalachiensis, Genabea cerebriformis e Hydnobolites cerebriformis, conocidos de los Estados Unidos de América y el Norte de México, hasta el Sistema Volcánico Transversal, mientras que Genea mexicana, Tuber pseudoseparans y T. tequilanum solo se conocen en este sistema montañoso.
