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).
•
The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
•
Based on ancestral reconstruction studies, the earliest (basal) members of the Sclerodermatineae originated in the late Cretaceous (145–66 Ma).
