Gelidium adriaticum sp. nov. andGelidium carolinianum sp. nov. (Gelidiales, Rhodophyta) from the Mediterranean Sea

Identification of small Gelidium species based on morphology is difficult; as a consequence, the name Gelidium pusillum has been used for many small gelidiacean taxa throughout the world. Molecular-assisted identifications, however, are demonstrating that G. pusillum has a more restricted distribution than previously recognised. We used detailed morphological analyses combined with rbcL and cox1 sequence analyses to identify and assess the...
