A new fruticulose species, Polycauliona comandorica, is described from the supralittoral zone of the Commander Islands in the Russian Far East. This growth form is very rare in the family Teloschistaceae where the new species belongs. It is the only fruticulose species of the family that forms vegetative propagules (soredia and blastidia). Polycauliona comandorica is similar to the North American P. thamnodes but differs in having a lighter yellow to grey thallus, longer and thicker branches with a rough surface, soredia and blastidia, and in lacking apothecia. Two fruticulose-lobate pairs of species in Polycauliona are briefly discussed: P. comandorica-P. verruculifera and P. thamnodes-P. brattiae.

Polycauliona comandorica，一种来自俄罗斯指挥官群岛的 Telosschistaceae 新果糖种

一个新的果糖物种，粗茎多茎，描述于俄罗斯远东指挥官群岛的滨海地区。这种生长形式在家庭中非常少见芋科新物种所属的地方。它是该科中唯一形成无性繁殖体（soredia 和blastidia）的果糖物种。粗茎多茎类似于北美P. thhamnodes但不同之处在于具有较浅的黄色至灰色的菌体，较长和较粗的分支，表面粗糙，孢子和芽孢，并且缺乏子囊。两个果糖-叶状物种对黄花菜简要讨论：P. comandorica-P. verruculifera和P. thhamnodes-P. brattiae.
