The genus contains two species found in north temperate areas that grow in a parasitic association with species of Scleroderma and Pisolithus.
Of the nine genera assigned to the Sclerodermatineae, three are hymenomycetes (Boletinellus, Gyroporus, and Phlebopus), and six are gasteroid (Astraeus, Calostoma, Diplocystis, Pisolithus, and Scleroderma).
