Description:
Diagnosis: From the protologue: 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.
Registration number: MB812363
Type species: Costatisporus cyanescens T.W. Henkel & M.E.Sm.
Nomenclature remarks: The only species described (as a sp. nov.) following the generic description on the same page is C. cyanescens. Satisfies valid publication according to Art. 38.5.
Ectomycorrhiza: Dicymbe, Aldina
Distribution: Guyana
Commentary: A relationship within Boletaceae is inferred from molecular analysis which relegates Costatisporus as a sister taxon to Sutorius.
