Fusitheca was a genus of land plant with branching axes.1 It is known from charcoalified Early Devonian deposits, its type locality being the Brown Clee Hill lagerstätten.2 Its spores form smooth-walled, unfused, naked dyads.3 Its axis comprises length-parallel filaments, and their dichotomies are T-shaped, with the branches bending to continue upwards.3
