Taxonomy and distribution of the green algal genus Codium (Bryopsidales, Chlorophyta) in Brazil
Codium is a marine green macro-algal genus, with cosmopolitan distribution, comprising about 125 species. Information about the representatives of this genus along the Brazilian coast is limited to a few floristic surveys in scattered localities. The present work presents the results of a survey of Codium along the Brazilian coast, with emphasis on the taxonomy and distribution of its component taxa. Material was collected from numerous beaches along the Brazilian coast, supplemented by samples in Brazilian herbaria and in California (Berkeley-UC). Eight species were recognized: C. decorticatum, C. intertextum, C. isthmocladum, C. profundum, C. repens, C. spongiosum, C. taylorii, and a repent Codium sp. A key to these species is given. Due to the great morphological plasticity observed in C. decorticatum, C. isthmocladum and C. taylorii, it was difficult to identify some specimens with certainty. C. isthmocladum, C. decorticatum, C. taylorii, and C. intertextum proved to have the widest distribution along the Brazilian coast.
