Description:
Defined meristem absent; thalli not differentiated into typical cortex and medulla, but composed of interconnected assimilatory filaments bearing rhizoidal filaments. Localised calcite husks surrounding specialised thin-walled calciferous cells. Rhizoidal filaments septate, occasionally developing from calciferous cells. Pit plugs with 2 cap layers; outer layer an enlarged dome. Vegetative cells uninucleate; secondary pit connections absent. Carpogonia or carpogonial branch initials sessile, or transformed terminal cells of secondary filaments. Carpogonial branches 2-celled. Carpogonia with a straight trichogyne. Auxiliary cells and connecting filaments absent. Gonimoblast initials formed directly by a fertilised carpogonium; gonimoblast filaments diffusely branched, ramifying unilaterally among assimilatory filaments and rhizoidal filaments without establishing fusions. Terminal cells of rhizoidal filaments facultatively fusing with intercalary gonimoblast cells, from which additional gonimoblast filaments are initiated, or these stages currently unknown [after Fredericq & Norris (1995)].
