A taxonomic study was recently carried out on species of the tribe Ceramieae (Ceramiaceae, Rhodophyta), following an evaluation of previously published records and on the basis of field and laboratory investigations. In Morocco, the tribe is represented by 5 genera: Ceramium (21 taxa at specific and infraspecific levels), Gayliella (3 species), and by one species each of Centroceras, Corallophila and Microcladia. Among these, there are five new records for Morocco: Centroceras gasparrinii, Ceramium botryocarpum, Ceramium cingulatum, Ceramium echionotum var. mediterraneum, and Gayliella taylorii. The report of C. echionotum var. mediterraneum from the Atlantic coast of Morocco is one of the rare records from outside the Mediterranean. Ceramium ciliatum var. robustum and Ceramium codii are recorded for the first time from the Atlantic coast of Morocco. Centroceras clavulatum is excluded from Moroccan flora having been misidentified for C. gasparrinii. This paper summarizes the taxonomic characters of these species with images and presents a key for their identification. This report is the first detailed record of the species of the tribe Ceramieae for Morocco. As a result, the total number of taxa at both specific and infraspecific levels accepted in the tribe Ceramieae for Morocco, under current taxonomy and nomenclature, is 27.

Rhodophyta is one of major groups in the number of species and diversity of the marine algal flora. The occurrence of Korean 5 red algal species is reported for the first time on the list of Korean marine algal flora based on morphology: Ceramium pacificum, Cumathanmnion serrulatum, Gayliella fimbriata, Leptofauchea rhodymenioides, Sorella pulchra. Ceramium pacificum from Korea is recognized by complete cortication, many adventitious branches in a radial arrangement, 7-8 periaxial cells, and plant length of 1-2 cm. Cumathanmnion serrulatum is characterized by cartilaginous single main axis with a prominent midrib, serrulate blade, many higher orders of bladelets on each blade, and tetrasporagia produced near the midrib acropetally and then outwardly. Gayliella fimbriata is featured by clavate gland cell and 5-7 periaxial cells. Leptofauchea rhodymenioides is characterized by erect with flattened, dichotomously branched fronds, 1-2 cortical cells loosely arranged, 2-3 cell medullar layers with large colourless cells. Sorella pulchrais recognized by short branches produced alternately pinnate manner from margins of axial, mostly polystromatic frond, and tetrasporangial sori on the center of branches.
