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. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. 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 Monday, 2 March 2026 +08:00.

Habit and structure. Thallus light pink, to 3 cm tall, caespitose or forming spherical clumps on other algae, mostly regularly dichotomously branched; successive dichotomies decussate or (rarely) complanate, with 1–4 (–8) intergenicula between dichotomies. Intergenicula terete, 80–150 μm diam., (rarely to 240 μm in distal parts of basal intergenicula subtending dichotomies), 340–750 μm long, shorter, narrower and more divaricate near the apices. Tetrasporangial conceptacles to 300–390 μm diam., with 2 surmounting branchlets. Tetrasporangia 140–200 μm long, 40–60 μm diam.

Distribution. Widespread in tropical and subtropical seas.

Habitat. Epiphytic or epilithic in the intertidal and subtidal.
