TYPE: Georgetown , Tasmania, Australia (Harvey, Alg. Aust. Exsiccata no. 419) ; lectotype designated by Womersley in 1952) in Herb. Harvey, TCD .

SPECIMENS EXAMINED: Port McDonnell, South Australia, coll. M. H. and F. Hommersand, 11.xi.95 ( WES 108). See Table 1.

GEOGRAPHIC DISTRIBUTION: Geraldton, West Australia to Jervis Bay, N.S.W. and around Tasmania,

Australia; Kermadec Isls (fide Nelson and Adams 1984, Womersley 1996), New Zealand ( Adams 1994).

The type specimen of Gloiosaccion brownii Harvey ( Fig. 17 ) at TCD was not available for examination. Univesiculate talli ( Fig. 18 ) from south Australia were preserved in silica gel and rehydrated for vegetative characters. Pyriform gland cells are cut off thallus inward from medullary cells in cross sectional ( Fig. 20 ) and surface ( Fig. 21 ) views. The surface shows complete cortication ( Fig. 22 ). The thallus interior is composed of three to six pigmented cortical cell layers and one to three medullary layers of hyaline cells ( Fig. 23 ).
