Fusitheca

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]
