Abstract The monotypic kallymeniacean genus Ionia established as Iona cornu-cervi is endemic to the Sea of Okhotsk. We observed type material species deposited in Komarov Botanical Institute Russian Academy Sciences (LE, St. Petersburg, Russia) and compared it with fresh collections near locality. Analysis rbc L dataset revealed that I. was not distinct from other genera Kallymeniaceae but consistently nested within Callophyllis formed a sister relationship variegata . Here, we propose new combination based on treat synonym distinguished by thallus many slightly convoluted segments positioned at an angle each other, forming erect more or less rigid plant, medulla composed intermingled large small cells.
