Service Notice

The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. The Herbarium team, working with the Biodiversity Information Office, now have the Nomos-hosted WACensus in production, and we will begin to update the flora and fungi for WA within the system soon. The Specify project team continues to test and streamline the new collections management system, and we expect this to be online in October. Please reach out to us if you have any questions or concerns.

The notice period started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Thursday, 1 October 2026 +08:00.

Scientific Description

Habit and structure. Thallus with prostrate and erect axes, the latter growing to a height of 1–2 mm. Prostrate axes with cells 90–110 µm diam. [L:B 2–3], attached by unicellular rhizoids with digitate pads. Erect axes with opposite lateral branches, the successive pairs rotated slightly; cells of erect axes 50–100 µm diam., gradually tapering from base to apex of the filament; apical cells 10–15 µm diam. Laterals initially overtopping the apical cell, becoming generally 3 cells long and branched once pseudodichotomously at the basal cell, with cells 30–45 µm diam. and with pointed apices.

Reproduction. Reproductive structures not seen.

Distribution. Known from Western Australia, South Africa and Samoa.

Habitat. generally epiphytic in the subtidal.
