Abstract A new species, Avrainvillea calithina, is described from Lord Howe Island and the southern Great Barrier Reef in eastern Australia. A member of the ‘longicaulis’ group of the genus, it is distinguished from its closest relatives by the ‘sugar-scoop’ form of the mature blades and the extremely cohesive outer siphon layers (pseudocortex) which ...

Abstract Four new species of Rhipiliopsis from eastern (R. gracilis, R. howensis, R. millarii) and western (R. multiplex) Australia and one new species (R. carolyniae) from the Philippines are described and compared anatomically with the type of the genus, R. peltata (J.

Fossil Udoteaceae and Gymnocodiaceae
1991The Gymnocodiaceae and fossil Udoteaceae (erect) are similar to each other both in growth form and in vegetative structure. They differ in that the Gymnocodiaceae contain internal reproductive organs which are usually absent in the Udoteaceae. It is generally accepted that the Gymnocodiaceae belong to the red algae and the Udoteaceae to the green algae.

Journal of Phycology, 2008
The placement of Avrainvillea and Cladocephalus in the family Udoteaceae (order Bryopsidales) has been questioned on the basis of nuclear, plastid, and other ultrastructural characteristics unique to these genera. Bayesian analysis of the chloroplast‐encoded LSU RUBISCO (rbcL) gene showed that the Udoteaceae is paraphyletic.

Planta, 1983
A dramatic tubular reorganization of the plastid envelope in injury-stressed cytoplasm of the siphonous green alga Chlorodesmis fastigiata is described and discussed as a process of membrane self-assembly under drastic changes in the microenvironment of the organelle.

Abstract In Chlorodesmis jastigiata, a remarkable variety of specifically structured material is found in the central vacuole immersed in an ill-defined granular-fibrillar matrix. This material fills the central vacuole throughout the entire length of the dichotomously branched cell of several centimeters' it is most dense in the tip.

Protoplasma, 1985
In the dichotomously branched caulerpalean green algaChlorodesmis fastigiata long range cytoplasmic streams run through the siphon and form a network of shorter strands in the region of the bulbous enlargement of the dichotomies. Continuous transport of organelles occurs along these streams, which are contructed of a central bundle of microtubules ...

Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1973
AbstractThe mucilages of this alga contain acid polysaccharides, some of which are Ca binding. After deproteinization and gel filtration the residue of the aqueous algal extract has the composition: 2% complexed protein, 3–4% Ca, 0.4–0.5% SiO2, 0.03–0.04% Al, ∼ 0.005% Fe, rest: polysaccharide. The molecular weights of the major and minor polysaccharide

The first record of Penicillus capitatus Lamarck from the Gulf of Antalya (Turkey) is reported. The species was found only in the typical stage in April, May and June 2006 and in June 2007. The occurrence of this tropical species in the Gulf of Antalya should be considered as a sign of the climatic change towards a “tropicalization” that is affecting ...
