Halecania australis is m far only known from the type locality, where it grew
on eutropMc rocks in a river bed in pasture land together wife mtropMious
lichens such as Candelaria emwolor. The genus Hakcanm is characterized by
halonate ascospores and a Catillam-type ascus and was placed in the *
Caullariaceae by M. Mayrhofer (1987, 1988). Hie genus consists of six
species. The new species can be distinguished from the similar Hakcama
alpimga (TM. FR.) M. MaYRH. and K ralM (SALWEY) M. Mayrh, by its
bright thallus colour and the thin (Mas wife a rough thallus surface.
Hakcama alpmga has a thicker and darker feallus and the apofeecial discs are
darker, while Jft raM.ii has a darker thallus wife a smooth surface, ft occurs m
coastal rocks in Scandinavia and fee British isles (Mayrhofer 1087).
