Crustose corallinaceous algae (Rhodophyta) of the New Zealand and United States scientific expedition to the Ross Sea, Balleny Islands, and Macquarie Ridge, 1965

Fourteen taxa of crustose Corallinaceae are described from a collection of marine algae picked up in Antarctic and sub-Antarctic waters along a Ross Sea — Balleny Islands — Macquarie Island traject aboard the USS Glacier in 1965. Three of these taxa are newly described, i.e. Lithothamnium macquariensis, L. zaneveldii and Phymatolithon lenormandii f. macquariensis. Two of the taxa recognized (Lithothamnium foecundum and L. laeve) appear to have a bipolar distribution. The remainder of the taxa collected are restricted to the southern hemisphere. The observed depth distribution of these crustose corallines shows that only one of the fourteen taxa is steno-eulittoral and four taxa are steno-elittoral. The remainder of the taxa cover a wide vertical range, i.e. from the eulittoral or sublittoral down into elittoral depths.
