Diagnosis: Distinguished from other Boletacaeae by a combination of the following characters: Basidiomata hypogeous to partially emergent, sequestrate. Peridium greyish yellow, staining dark blue, glabrous to subtomentose, thin. Gleba brown, unchanging, loculate, sterile veins absent. Basidiospores statismosporic, subglobose to oblong, light brown, inamyloid, with costate ornamentation of longitudinal ridges pole to pole, these entire or discontinuous, pedicel infrequent. Basidia clavate. Cystidia and clamp connections absent.
