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