Two new species are recognized, one is assigned to Matonia, and another to the emended gleicheniaceous form-genus Gleicheniaceaephyllum. The taxonomy of fossil genera assigned to Gleicheniaceae is problematic, and as an alternative to the invalid genus Gleichenites, we propose that Microphyllopteris be utilised as a form-genus for species that have either an unknown branching pattern or pseudo-dichotomous branching without resting buds; Microphyllopteris is reserved for ferns that cannot be ascribed conclusively to Gleicheniaceae. Alternatively, Gle..
