Distributional notes
Australia at Lord Howe Island, New South Wales; Port Phillip Heads, Victoria; Rottnest Island, Western Australia.

General environment
This is a marine species.

Description
Thalli membranous, 3-5 mm in width between irregularly scattered perforations; surface vegetative cells in lateral profile broader than long, distally broadly rounded; hair primordia tufted, scattered on surface in shallow identations rather than pits, the distal cells moniliform and seldom extending into hairs; plurangial sori discretely bordered, encircling central tufts of hairs/hair primordia, to 350 µm in diameter, not extending over the thallus surface. Plurangial palisades compact, the plurangia sessile on cortical bearing cells.

Habitat
Thalli have been collected from September through January at Lord Howe Island. Although many specimens occurred at depths >5 m, others were collected sympatrically with H. clathratus in shallow subtidal and even low-intertidal habitats. Collections of fertile material were made at 5-6 m and 13 m depths, respectively, in Victoria and Western Australia.
