Description:
Thalli erect, uncalcified, dichotomously or subdichotomously branched, rarely irregular. Axes terete or compressed. Structure multiaxial; medulla of longitudinal filaments bearing anticlinal, subdichotomously branched assimilatory filaments forming a cortex; cortex remaining filamentous or becoming pseudoparenchymatous. Spermatangia borne on outer cortical cells or within cavities. Carpogonial branches on inner cortical filaments, 3-celled, hypogynous cell bearing nutritive cells. Gonimoblast developing directly from carpogonium. Cystocarps within outer medulla, not protuberant, with branched gonimoblast filaments and terminal carposporangia, when mature with a distinct pericarp formed from filaments arising from the basal cell of the carpogonial branch, ostiolate. Tetrasporophytes (where known) either filamentous (<i>Scinaia, Gloiophloea</i>) or crustose (<i>Nothogenia</i>), with cruciately divided tetrasporangia.
