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.

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.
