Electronic Flora of South Australia Genus Fact Sheet

Genus KUETZINGIELLA Kornmann in Kuckuck 1956: 293, 314

Phylum Phaeophyta – Order Ectocarpales

Thallus of prostrate filaments of short cells on the host surface and relatively short, erect, simple or slightly branched filaments; basal filaments appressed, becoming pseudoparenchymatous; erect filaments without phaeophycean hairs but often tapering into false hairs. Growth diffuse or from short, scattered, meristematic regions. Cells with numerous discoid phaeoplasts each with a pyrenoid.

Reproduction: Reproduction by plurilocular organs and unilocular sporangia, sessile on the basal layer or on 1–3 celled pedicels lateral on the erect filaments.

Type species: K. battersii (Bornet) Kornmann in Kuckuck.

Taxonomic notes: A genus of only a few (3?) species which occur epiphytically on the surface of other algae. Kuetzingiella sp.

Clayton (1974, p. 794, fig. 31) described an unnamed species of Kuetzingiella from Apollo Bay, Point Lonsdale and Sorrento, Vic., either epilithic or epiphytic on Hormosira and Xiphophora chondrophylla. She considered it to differ from other species of the genus in having long, narrow, plurilocular sporangia, and she also compared it to the genus Herponema.

Further studies are needed to establish and characterise the occurrence of Kuetzingiella in southern Australia.
