Description:
Thallus (gametophyte) erect, mucilaginous, radially or irregularly branched. Structure uniaxial, with whorls of 4 or 5 lateral branches from each axial cell, these later supplemented by additional branches. Spermatangia in terminal clusters. Auxiliary cells terminal in simple, occasionally compound or sparsely branched filaments composed of 4 or more cells; a single gonimoblast initial produced following diploidisation, most cells ultimately converting to carposporangia. Life history triphasic, with heteromorphic gametophytes and tetrasporophytes, the latter, where known, having a loose or compact crustose morphology.

Nomenclatural notes:

Included in the Cryptonemiales F.Schmitz (1892: 21) by Athanasiadis (2016: 582).
