Scientific Description
Habit and structure. Thallus to 4 mm tall, light red. Primary axes ecorticate, 60–100 µm diam.; periaxials 200–250 µm long; pseudolaterals to 1.2 mm long, 2 or 3 times dichotomously divided from suprabasal cell, every (1 or) 2 cells; ultimate branches 8–10 cells long. Basal cell of pseudolateral 40–60 µm diam. [L:B c. 1], more distal cells 25–35 µm diam. [L:B 3–4], tapering to elongate cells 10–15 µm diam.
Reproduction. Only immature tetrasporangial stichidia known in the north-western Australia collection, these arising as 1 branch of the second dichotomy of pseudolaterals, with a 1- or 2-celled pedicel, and 7 or 8 fertile segments each with 4 tetrasporangia. Sporangial cover cells 2 per tetrasporangium.
Distribution. Widespread in warmer seas.
