Molecular analyses including type material of P. lamii and P. laevigatum were congruent in delimiting P. lusitanicum as an independent lineage from these crustose species. The three species shared a common external morphology of multiporate asexual conceptacles, but P. lusitanicum has been detected only unattached as maerl while P. lamii and P. laevigatum are crustose. Phymatolithon lusitanicum is particularly abundant in subtidal maerl beds of the Atlantic Iberian Peninsula (Galicia and the Algarve); however it has also been detected northwards in Ireland intertidally and in Western Mediterranean Sea (Alborán Sea, Balearic Islands) down to 64 m.

The name was given to indicate that unidentifi ed coralline algae are the major component. In this fi rst contribution to the knowledge of the coralline fl ora of the Litavac, Lithoth- amnion valens seems to be the most common species, with an unattached, branched growth-form. Small rhodoliths composed of Phymatolithon calcareum and Mesophyllum roveretoi also occur. The Badenian benthic association is dominated by melobesioid corallines, thus it can be compared with the modern maërl facies of the Atlantic Ocean and Mediterranean Sea. Since L. valens still survives in the present-day Mediterranean, an analogy between the Badenian Litavac and the living L. valens facies of the Mediterranean is suggested.

  • It Was Recognized During Geological Excursions in the Bükk Mountains
    NEWER LIME-SECRETING ALGAE FROM THE MIDDLE CARBONIFEROUS OF THE BÜKK MOUNTAINS, NORTHERN HUNGARY M. NEMETH INTRODUCTION It was recognized during geological excursions in the Bükk Mountains that certain limestone lenses of the Upper Moscovian shale sequence yield other calcareous algae than those dasycladaceans (Vermiporella sp., Anthracoporella sp., A. spectabilis PIA and Dvinella comata CHVOROVA) described previously by HERAK, M. and Ko- CHANSKY, V. [1963]. From limestone samples came from the No. 1 railway cutting of Nagyvisnyó, from the eastern side of the Bánvölgy (NW to the Dédes Castle), from the southern vicinity of the village Mályinka, from Kapubérc, from western side of the summit of Tarófő and from deeper part of the main lens of Nagyberenás the forms of the genera Archaeolithophyllum, Ivanovia, Oligoporellal and Osagia have been recognized. The first two genera belong into the phylloid algae of PRAY, L, C. and WRAY, J. L. [1963]. The genus Macroporella is classed among the family Dasydadaceae, while the Osagia is a crustose calcareous alga of uncertain systemat- ic position. Most interesting are the phylloid algae, which are similar in shape and size to leaves and are slightly or strongerly wavy, in spite of the morphological similarity that suggested by their common name, these are forms of different groups (e.g. green or red algae). This group was named by American authors, because these phylloid algae are abundant, occasionally in rock-forming quantity in the Middle and Upper Carboniferous (Pennsylvanián) and Lower Permian of the USA. On the other hand, the preservation of the cavities between the wavy plates of these algae pro- motes significantly the formation of hydrocarbon traps within the embedding rocks.

Both former names (1976) and current names are provided. This list is organized by group (green, brown, red algae); within each group are genera and species in alphabetical order. California seaweeds discovered or described since 1976 are indicated by an asterisk. This is a draft of an on-going project. If you have questions or comments, please contact Kathy Ann Miller, University Herbarium, University of California at Berkeley.

E-mail: [email protected] Abstract A taxonomic reassessment of coralline algae (Corallinales, Rhodophyta) associated with reef environments in the Abrolhos Bank, northeastern Brazil, was developed based on extensive historical samples dating from 1999–2009 and a critical evaluation of type material. Our goal was to update the taxonomic status of the main nongeniculate coral reef-forming species. Our results show that four species are the main contributors to the living cover of coral reefs in the Abrolhos Bank: Lithophyllum stictaeforme, Neogoniolithon atlanticum sp.
