Itajahya is a fungal genus in the family Phallaceae. The genus, widespread in tropical and subtropical areas, contains three species. Characters in this genus include a white calyptra (tissue which covers the top of the fruit body to which the gleba is attached), and lamellate plates covered with gleba. The gleba has a white mottled surface, and the cap appears wig-like when removed of the gleba. The thick, stout stalk has many chambered walls. The species , formerly classified in the genus Phallus, was transferred to Itajahya in 2012 when molecular phylogenetic analysis revealed that it was not closely related to other Phallus species.
