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.

Prostrate system of sparingly and irregularly branched discrete filaments creeping within the host; cells irregular to subcylindrical, 12–80 µm long, 6–15 µm diam. [L:B 1–8]. Erect filaments simple or sparingly and irregularly branched, to 400 µm long; cells irregular to cylindrical, 15–50 µm long, 3–15 µm diam. [L:B 1–5]. Plastids lobate to stellate. Terminal and pseudolateral hairs to 450 µm long.

Reproduction. Monosporangia ovoid, 13–35 µm long, 10–18 µm diam., terminal or lateral, sessile or stalked, on prostrate or erect filaments.

Distribution. Widespread in tropical to temperate seas.

Habitat. Generally endophytic in species of Liagoraceae.
