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.

Scientific Description

Habit and structure. Thallus red to red-purple, 1–5 mm high, frequently branched alternately to subdichotomously with the new lateral displacing the axis above it, attached by an unspecialised basal cell; epiphytic. Filaments 15–20 µm in diameter, with a uniseriate row of closely adjacent cells 8–12 µm in diameter within the thick mucilaginous sheath; cells isodiametric (L/B 0.5–2) with rounded to angular corners, rhodoplasts stellate, with a central pyrenoid.

Reproduction. By release of vegetative cells as monospores, by dissolution of the sheath matrix.

Distribution. Virtually cosmopolitan.

Habitat. A common epiphyte on a variety of hosts.
