ABSTRACT
The non geniculated coralline algae, represented by the order Corallinales are largely distributed in all seas, occur from the tidal zone down to deep regions and present highly important ecological and economical role. Although these, non geniculated coralline algae are poorly known in Brazil. In order to contribute to the taxonomic knowledge of these algae group, in this work it was presented descriptions of three species from Bahia State coast: Sporolithon episporum, Mesophyllum erubescens and Lithophyllum stictaeforme.
Key words: coralline algae; Corallinales; Sporolithon; Mesophyllum; Lithophyllum
