Japan Abstract – Sporolithon ptychoides Heydrich (Sporolithaceae, Sporolithales), the type species of the genus Sporolithon, is newly reported for Thai waters based on specimens collected from the Gulf of Thailand and the Andaman Sea. Adetailed morphological and anatomical account is provided, including comparisons with published data of S. ptychoides and its related species. Epithallial cells are flared. Cells of adjacent filaments connect laterally mostly by secondary pit connections. Tetrasporangia are grouped in sori that occur in patches over the thallus surface. Sori are buried in distinct rows in the thallus. Details of male, female and carposporangial conceptacles of S. ptychoides are described for the first time. Gametangial thalli are monoecious with spermatangia and carposporangia born in uniporate conceptacles. Dendroid spermatangial branches occur on the floor, walls and roof of the male conceptacle chamber. Carpogonial branch consists of ahypogenous cell and a carpogonium. Central fusion cell is absent on the floor of the carposporangial conceptacle chamber.

  • Integrating Phylogeny, Molecular Clocks, and the Fossil Record in the Evolution of Coralline Algae (Corallinales and Sporolithales, Rhodophyta)
    Paleobiology, 36(4), 2010, pp. 519–533 Integrating phylogeny, molecular clocks, and the fossil record in the evolution of coralline algae (Corallinales and Sporolithales, Rhodophyta) Julio Aguirre, Francisco Perfectti, and Juan C. Braga Abstract.—When assessing the timing of branching events in a phylogeny, the most important tools currently recognized are a reliable molecular phylogeny and a continuous, relatively complete fossil record. Coralline algae (Rhodophyta, Corallinales, and Sporolithales) constitute an ideal group for this endeavor because of their excellent fossil record and their consistent phylogenetic reconstructions. We present the evolutionary history of the corallines following a novel, combined approach using their fossil record, molecular phylogeny (based on the 18S rDNA gene sequences of 39 coralline species), and molecular clocks. The order of appearance of the major monophyletic taxa of corallines in the fossil record perfectly matches the sequence of branching events in the phylogeny. We were able to demonstrate the robustness of the node ages in the phylogeny based on molecular clocks by performing an analysis of confidence intervals and maximum temporal ranges of three monophyletic groups of corallines (the families Sporolithaceae and Hapalidiaceae, as well as the subfamily Lithophylloideae). The results demonstrate that their first occurrences are close to their observed appearances, a clear indicator of a very complete stratigraphic record. These chronological data are used to confidently constrain the ages of the remaining branching events in the phylogeny using molecular clocks. Julio Aguirre and Juan C. Braga.

  • An Account of Common Crustose Coralline Algae
    D.I. Walker and F.E. Wells (Eds) 1999. The Seagrass Flora and Fauna of Rottnest Island, Western Australia. Western Australian Museum, Perth. CORE An account of common crustose coralline algae Metadata, citation and similar papers at core.ac.uk Provided(Corallinales, by Research Repository Rhodophyta) from macrophyte communities at Rottnest Island, Western Australia. by C.B. Sim Department of Botany, University of Western Australia, Nedlands, 6907, Western Australia and "' R.A. Townsend School of Biological Sciences and Biotechnology, Division of Science and Engineering, Murdoch University, Murdoch 6150, Western Australia ABSTRACT Meaningful interpretation of ecological experimentation can only be made after knowledge of the floral composition of an area is known. Crustose coralline algae have a reputation among phycologists as being a difficult group of organisms to identify to species level. Crustose coralline algae (Corallinales, Rhodophyta) cover the substratum in most macrophyte communities; their ecology is poorly understood. The aim of this work was to develop a species list and generic key for crustose coralline algae found in macrophyte communities around Rottnest Island, Western Australia. Eleven species belonging to seven genera were identified from limestone substrata in kelp and mixed macroalgal communities. A key to the common genera of crustose coralline algae found in these communities is also provided. The key, aimed at ecologists with limited knowledge of coralline taxonomy and anatomy, uses gross external and easily recognisable internal characters. The crustose coralline algal flora of Rottnest Island is a mixture of Indo-West Pacific and southern temperate species. Species such as Hydrolithon onkodes which has an extensive tropical and subtropical range were found at most sites sampled.

Keats a a Department of Biodiversity & Conservation Biology, University of the Western Cape, Private Bag X17, Bellville 7535, South Africa b Institute of Marine Sciences, University of Portsmouth, Ferry Road, Portsmouth, PO4 9LY, UK Received 15 May 2007; received in revised form 14 December 2007; accepted 4 February 2008 Abstract Non-geniculate coralline red algae are common in all of the world's oceans, where they often occupy close to 100% of the primary rocky substratum. The South African rocky subtidal and intertidal habitats in particular, are rich in diversity and abundance of non-geniculate coralline red algae. Despite their ubiquity, they are a poorly known and poorly understood group of marine organisms. Few scattered records of non- geniculate coralline red algae were published prior to 1993, but these should be treated with caution since many taxa have undergone major taxonomic review since then. Also, generic names such as Lithophyllum and Lithothamnion were loosely used by many authors for a host of different non-geniculate coralline algae. A series of taxonomic studies, based mainly on the Western Cape Province of South Africa, published particularly between 1993 and 2000, has significantly extended our knowledge of these algae from southern Africa. References to these latter papers and the older records are now gathered here and a list of the well delimited families (3), subfamilies (4), genera (17) and species (43) are presented.

Por lo general no es posible identificar con certeza las especies que forman los rodolitos con base únicamente en la forma en que crecen u otras características morfológicas externas. Para una identificación precisa y confiable normalmente se requiere realizar cortes histológicos para examinar los caracteres vegetativos y reproductivos pertinentes. En este trabajo se presentan pasos simplificados para facilitar la identificación de rodolitos de algas rojas coralinas no geniculadas. El proceso de identificación se divide en dos etapas y consiste en identificar los especímenes a nivel de género, en primera instancia, y a nivel de especie, en segunda. Se han registrado aquí los géneros comunes de algas no geniculadas formadoras de rodolitos (Hydrolithon, Neogoniolithon, Lithophyllum, Sporolithon, Lithothamnion, Phymatolithon, Mesophyllum y Spongites), y se proporcionan ilustraciones y/o referencias de caracteres taxonómicos importantes de utilidad para la identificación de especímenes a nivel de género. También se proporciona bibliografía de publicaciones recientes sobre descripciones florísticas o estudios taxonómicos detallados de especies formadoras de rodolitos de estos ocho géneros para facilitar su identificación. Palabras clave: rodolitos, algas coralinas, identificación, Corallinales. Abstract Rhodoliths are free-living structures composed mostly of nongeniculate coralline red algae.

(Received 0I July, 20 I0; revised version accepted 26 August, 20 I0) ABSTRACf Ghosh AK & Sarkar S 20 IO. Contemporary taxonomic perspectives offossil Coralline Red Algae: their possible origin and evolution. The Palaeobotanist 59(1-3) : 107-119. Studies done by various phycologists have brought about remarkable changes in the present-day coralline algal taxonomy. The taxonomy offossil coralline red algae also has been under the process of continuous revision and modification since 1993. Prior to 1993 it was believed that several diagnostic characters used in recent coralline red algae were unpreservable in fossil forms. Palaeoalgologists have now understood the value ofunification oftaxonomy, for extant and fossil corallines to accurately interpret the phylogeny, palaeoecology and palaeobiogeography. Phylogenetically, the corallines are very important as they represent a major evolutionary line within the red algae as evidenced by anatomical studies on recent forms as well as various studies on gene sequence analysis. The present contribution deals with the remarkable changes that have taken place since 1993 in the taxonomic aspects offossil coralline algae and the modern trends ofresearch in this context. Presently, an attempt has been made to establish the possible origin and evolution ofcoralline red algae.
