Tricarinella crassiphylla Savoretti, Bippus, Stockey, G.W.Rothwell et Tomescu
Gametophyte three-dimensionally branched. Stem terete basally, triquetrous distally; central strand present. Phyllotaxis tristichous, helical. Leaves lanceolate, keeled. Costa homogeneous. Lamina entirely bistratose at leaf base, bistratose sectors adjacent to costa distally, marginal sectors unistratose. Bistratose sectors taper apically; lamina unistratose in apical half of leaf. Lamina cells sinuous near leaf base.
Tricarinella for the strongly three-edged profile of the shoot, which is due to strongly keeled three-ranked leaves (tri = three; carina = keel; the suffix -ella signifies a diminutive, for the small size of the gametophyte).
