Grisellatheca 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 lagerstatten.[2] Its Terahedraletes spores form permanent tetrads.[3]

Grisellatheca's internal anatomy comprises banded tubes, but it lacked an external cuticle.[3] It shows some liverwort characteristics, and is hesitantly assigned to this group.[3]
