Description
Size: Height: 3-4 mm.

Plants forming dense, felted tufts. Basal system endophytic, composed of very irregularly ramified filaments, developing branches in all directions between the filaments of the host; some of the branches rhizoid-like, growing inwardly into the tissue of the host. Cells of the basal system 22 µ broad and 2-5 times as long. Erect system composed of almost cylindrical cells, 18-25 µ thick and one to six long, constricted at the cross walls, chromatophores discoid, irregularly strap-shaped or roundish. Most of the erect filaments unbranched; only few producing one or few branches. Intercalary meristem situated at about the middle of the filament.

Plants bearing only plurilocular sporangia; the latter scattered on the filaments; generally sessile, occasionally pedicellate; more or less obliquely elongated, conical and irregularly constricted or sinuate; 140 µ long and 23-35 µ broad.
