—Filaments are monoecious, attached by sparingly branched rhizoids to the soil substrate, 30–45(53) µm in diameter. Gametangia are born on fruiting branches (gametophores), which appear laterally and terminally and do not any differ in diameter from filaments. Fruiting branches usually consist of 1(2) oogonia borne laterally to 1 antheridium; gametangial pedicels are strongly curved and positioned at ca. 45–90-degree angles apart to each other (
