Species of megaspores similar to lower Cretaceous Pyrobolospora hexapartita and Minerisporites marginatus from European localities are recorded for the first time from various Jurassic and Cretaceous localities of Australia. Descriptions of new species of the new genus Balmeisporites, new species of Pyrobolospora, and the microspore Perotrilites striatus n.sp. are given, and the possible affinity of Pyrobolospora with Perotrilites striatus n.sp. is discussed.
