Evidence is presented that the marine macroalga Pseudobryopsis papillata Nasr (Bryopsidaceae, Chlorophyta), described by Nasr in 1944 from the Red Sea, is conspecific with the Mediterranean generitype Pseudobryopsis myura (J. Agardh) Berthold in Oltmanns. Although Ps. myura was originally depicted as having non-papillate gametangia, recent and past collections of this species in the Mediterranean clearly show papillate gametangia, thus erasing the primary reason for distinguishing it from Red Sea populations. In addition, similar branch patterns and thallus lengths support the synonymization of these two species. [ABSTRACT FROM AUTHOR]

The occurrence of the red algal species Hypoglossum caloglossoides (Delesseriaceae, Ceramiales) is reported for the first time from shallow sub-littoral sites in both the Mediterranean Sea and the Red Sea. This small but morphologically distinctive species, originally described from Lord Howe Island in the southwestern South Pacific Ocean, has been recorded from scattered tropical and subtropical locations around the globe. Some aspects of its ecology in the north Israeli Mediterranean are also discussed. [ABSTRACT FROM AUTHOR]
