Cylindrocarpus kuckuckii sp. nov. (Chordariaceae, Phaeophyceae), a newly recognized species from the Aegean Sea (Turkey)
Taskin, Ergün Wynne
Cylindrocarpus kuckuckii sp. nov. (Chordariaceae, Phaeophyceae) is described on the basis of two collections from Ayvalik, Turkey (Aegean Sea). This taxon has been recognized for more than a century by several workers, starting with Kuckuck (1899), as a form of C. microscopicus which is the type and hitherto only recognized species in the genus. Evidence is presented here that C. kuckuckii can be distinguished from C. microscopicus at the species level by its epilithic habit, the pseudodichotomous nature of its erect branches, the larger sizes of the cells of the assimilatory filaments, the relatively larger size of the plurilocular sporangia and its larger overall thallus dimensions.
