Diagnosis Thalli, approximately 2.5 cm tall, form tufts of interwoven filaments, which have the appearance of a frayed rope at its tips (Fig. 13). Filaments are uniseriate and irregularly branched with numerous short hooked branches arising at an angle of 80-90°. Growth takes place by intercalary cell divisions. Cells are 25-33 μm wide, 60-80 μm long, L/B: 1-1.3. Plurilocular sporangia, placed on a 1-2-celled stalk, are spherical to ovoid and measure 40 x 42 (-63) μm on average (Ref. 82093). It is characterised by the shape of the plurilocular sporangia and the presence of short hooked branches (Ref. 82093).
