Spores alveolate-reticulate to reticulate or with pit-like perforations, extremely rarely rugulose and with crater-like pits, subfusoid, elongate-ellipsoid to short ellipsoid, lacking a suprahilar plage. Hymenial cystidia present. Clamp connections absent.
Distribution: NE Asia to SE Asia, Australia, SE USA, Mexico, Belize, and Costa Rica.
