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 Genus Phymatolithon (Hapalidiaceae, Corallinales, Rhodophyta) in South Africa, Including Species Previously Ascribed to Leptophytum

In recent publications, the Received in revised form 4 November 2013 name Leptophytum was used in quotation marks because South African taxa ascribed to this genus had not Accepted 5 November 2013 been formally transferred to another genus or reduced to synonymy. The status and generic disposition of Available online 7 December 2013 those species (L. acervatum, L. ferox, L. foveatum) have remained unresolved ever since Düwel and Wegeberg Edited by JC Manning (1996) determined from a study of relevant types and other specimens that Leptophytum Adey was a heterotypic synonym of Phymatolithon Foslie. Based on our study of numerous recently collected specimens and of published Keywords: data on the relevant types, we have concluded that each of the above species previously ascribed to Leptophytum Non-geniculate coralline algae represents a distinct species of Phymatolithon, and that four species (incl. P. repandum)ofPhymatolithon are Phymatolithon acervatum currently known to occur in South Africa. Phymatolithon ferox Here we present detailed illustrated accounts of each of the four species, including: new data on male and female/ Phymatolithon foveatum carposporangial conceptacles; ecological and morphological/anatomical comparisons; and a review of the infor- Phymatolithon repandum mation on the various features used previously to separate Leptophytum and Phymatolithon. -

OLIVEIRA4 (received: July 04, 2007; accepted: February 23, 2011) ABSTRACT – (Morphology and reproduction of Mesophyllum erubescens (Foslie) Me. Lemoine (Corallinales, Rhodophyta) from Southern Brazil). The genus Mesophyllum Me. Lemoine includes around 147 species, of which only three have been referred to the Brazilian coast. Mesophyllum erubescens was originally described from Fernando de Noronha Archipelago, Brazil (type locality). Here we present the first detailed description of M. erubescens based on Brazilian material. Samplings were made through scuba diving at the Biological Marine Reserve of Arvoredo Island, Santa Catarina. The relations of M. erubescens with other similar species, especially from the American Atlantic studied by W.R. Taylor are discussed. Key-words - Arvoredo Island, mäerl, rhodolith bed, seaweed taxonomy RESUMO – (Morfologia e reprodução de Mesophyllum erubescens (Foslie) Me. Lemoine (Corallinales, Rhodophyta) do Sul do Brasil). O gênero Mesophyllum Me. Lemoine compreende cerca de 147 espécies, das quais apenas três são referidas para a costa brasileira. Mesophyllum erubescens foi originalmente descrita para o Arquipélago de Fernando de Noronha, Brasil (localidade tipo). Neste trabalho é apresentada a primeira descrição detalhada de M. erubescens baseada em material brasileiro. As amostragens foram realizadas através de mergulho autônomo na Reserva Biológica Marinha do Arvoredo, Santa Catarina. As relações de M. erubescens com outras espécies semelhantes são discutidas, sendo especialmente consideradas espécies do Atlântico Americano estudadas por W.R.
