New insights into the cryptic diversity of the North Atlantic-Mediterranean Porphyra leucosticta complex: P. olivii sp. nov. and P. rosengurttii (Bangiales, Rhodophyta)
Abstract.The existence of cryptic diversity in the Porphyra leucosticta complex of the North Atlantic and Mediterranean was confirmed from a wide variety of recent and over 100-year-old herbarium specimens using plastid and nuclear molecular data in combination with karyological, morphological and e...
