Crayweed[1] (Phyllospora comosa) is a species of brown algae in the Seirococcaceae family. It is found in the oceans around Australia and New Zealand.[2]
In Australia, Phyllospora comosa is abundant in cooler waters along the south-eastern coastline, around Tasmania and in South Australia. It occurs to a depth of around 5 m (east coast) and farther south to about 3 m, but it can be found on some Tasmanian coasts at 18 m depth. It used to occur around Sydney but has disappeared and now it is being re-established under the Crayweed Restoration Project. It grows up to 2.5 m in length and forms dense, shallow forests. The algae have a central main axis, usually up to 3 m long, which bear many branches, along their length, with closely arranged, leaf-like laterals. Some laterals have conceptacles, in which develop cells which produce sperm and eggs. The strongly seasonal growth of the algae depends on the length of daylight; it occurs from apical cells and is restricted to the top 20–30 cm of the branches.
