Abstract:
Taxonomic revision revealed that the genus Porphyra is represented in the northern seas of Russia by 5 species - monostromatic P. leucosticta, P. purpurea, P. umbilicalis and distromatic P. miniata, P. amplissima. Previous records of P. abyssicola in the Barents and White Seas are in error and trans-ferred to various species. P. laciniata sensu A. Zinova (1955) is P. purpurea, which is common to Murman coast of the Barents Sea and infrequent in the White Sea. P. leucosticta is recorded for the first time in Russia on Murman coast. Based on a study of type specimens P. helenae and P. miniata. P. helenae is considered conspecific with P. miniata. The latter is characterized by reproductive thallus divided longitudinally into male and female sectors and closely related to Pacific P. variegata. P. amplissima differs in having mixed spermatangia and carposporangia along the margin of mature thallus. The distribution of Porphyra species in Eurasian sector of the Arctic Ocean is limited to high boreal waters - Murman coast of the Barents Sea and the White Sea. Taxonomy, distribution, relationships of species are discussed. Descriptions of species based on material studied are given.
