Some Delesseriaceae (Ceramiales, Rhodophyta) new to the southwestern Atlantic

Abstract

-(Some Delesseriaceae (Ceramiales, Rhodophyta) new to the southwestern Atlantic). Up to now 18 species of Delesseriaceae have been referred to the Brazilian coast, nine of which belong to the subfamily Delesserioideae. Here we report for the first time the occurrence of Apoglossum gregarium (Dawson) Wynne, Branchioglossum minutum Schneider and Hypoglossum anomalum Wynne & Ballantine collected by SCUBA diving on islands of the south and southeastern coast of Brazil. This report is an indication that the subtidal has been undersampled on the southwestern Atlantic. RESUMO-(Algumas Delesseriaceae (Ceramiales, Rhodophyta) novas para o sudoeste do Atlântico). Até agora 18 espécies de Delesseriaceae (Rhodophyta) foram citadas para a costa brasileira, dentre as quais nove pertencentes à subfamília Delesserioideae. Aqui reportamos, pela primeira vez, a presença de Apoglossum gregarium (Dawson) Wynne, Branchioglossum minutum Schneider e Hypoglossum anomalum Wynne & Ballantine coletadas através de mergulho autônomo em ilhas do sul e sudeste do Brasil. Esta é mais uma contribuição mostrando que a biodiversidade algal do infralitoral é ainda pouco conhecida no Atlântico Sul Ocidental.

Descriptions of Cottoniella fusiformis, Branchioglossumcf. minutum and Frikkiella searlesii (Rhodophyta, Ceramiales) from the Brazilian continental shelf

“…Our specimens present ellipsoid tetrasporangial sori (Fig. 2G), differing from the circular or semicircular sori described for the type species (Schneider & Searles 1975) and for Brazilian specimens reported by Horta & Oliveira (2001). Although the ellipsoid tetrasporangial sori in one row on both sides of the midrib is a feature also present in Branchioglossum nanum Inagaki, our specimens differ in relation to the dichotomy of branches (Inagaki 1935).…”

“…Despite the small stature of this algal species (less than 10 mm in height) and its usual deep sublittoral habitat, Apoglossum gregarium has been reported to occur from scattered tropical, subtropical, and warm temperate locations, including southern California (Stewart 1974(Stewart , 1989, Puerto Rico (Ballantine & Wynne 1985), Kwazulu-Natal, South Africa (Wynne & Norris 1991), Italy (Sartoni & Boddi 1993), the Mediterranean coast of Spain (Clavell & Polo 1998, 2000, Hawaii (Abbott 1999), Bermuda (Schneider 2000), the State of São Paulo, Brazil (Horta & Oliveira 2001), Korea (Park et al 2006), Greece (Tsiamis & Bellou 2010), Venezuela (Gómez et al 2013), and the northern Gulf of California, Mexico (Norris 2014). It is an easily recognized species because the usually simple blades often arise from a shared prostrate stolon and have a ruffled, undulate appearance, and they have a conspicuous uncorticated midline.…”
