Overview of thallus

The species was found for the first time in Norway 17 April 2007 at Store Karlsøy, Hordaland. It was collected again at the same locality during September 2007, and identified (see Rueness et al. 2007 Aquatic Invasions 2: 431-434, for a detailed description of the species). This species is probably introduced to Europe from the Pacific Ocean with ballast water. In Europe it has earlier been recorded (as A. pectinatum) in the Mediterranean and in Spain. The specimens at Store Karlsøy were found in the intertidal zone epiphytic on Corallina officinalis and Laminaria sp. The gland cells found adaxial on the last order of branches cover two cells and are one of the characteristics that distinguish it from other species with gland cells.




Axes carry pairs of opposite branches (pinnae), very densely packed in the apices.

The pinnae carry pinnules in opposite pairs. The last 2-3 pinnules of a pinna grow abaxially. The pinnae have a characteristic small and isodiametric basal cell. Arrows showing gland cells.




Gland cells covering two cells, situated at adiaxial side of the pinnules (small side branches).
