Abstract

The genus Mesenteriophyllum, described by T.A. Sistel in Kyrgyzstan and known in Australia and Antarctica, is revealed on the Taimyr Peninsula. The new species Mesenteriophyllum sixtelae with a transversely wavy thallus is described there. Morphologically similar plants were found in Central Siberia. The genus Kotchumdeckia is distinguished there, differing from Mesenteriophyllum by a flat thallus and a broad flattened marginal border. The newly described species Mesenteriophyllum sixtelae, Kotchumdeckia borutchinkinae, K. clavata, and K. parallela differ in the shape of the thallus. These plants belong to Phaeophyta. There are some Phaeophyta thalli overgrown with Cyanobionta.
