Description:
Diagnosis: Basidiomata secotioid to gasteroid, hypogeous to nearly epigeous, soft-textured, primarily pale yellow then ochre to light brown. Stipe-columella usually present, forming dendritic sterile tissue. Gleba dry, loculose with empty locules, whitish to grayish white, soon bluish to purplish when cut and exposed. Spores hyaline to pale ochraceous, with pyramidal conical spines, dextrinoid. Hymenial cystidia absent. Peridial surface formed from filamentous interwoven hyphae. Clamp connections absent.
Registration number: MB 513563
Type species: Octaviania columellifera Kobayasi, Bot. Mag., Tokyo 51: 297. 1937.
Ectomycorrhiza: Expected with Pinaceae, Fagaceae
Distribution: Japan
Commentary: Inferred alliance to Xerocomellus chrysenteron complex of epigeous boletes according to describing authors (Orihara et al 2010) based on nuclear ribosomal genes. Morphologically reminiscent of Octaviania.
