Despite ongoing moss flora research in the Russian Far East, the bryoflora of Koryakia remains relatively poorly studied. A brief excursion to Karaginskii Island in August 2023 revealed 112 bryophyte species. With the previously published data and our additions, the total number of moss species on the island is 142. We identified 36 species that are new to the “Southern Koryakia” region of the northern Russian Far East. The most interesting findings are Brachythecium frigidum, Bucklandiella macounii subsp. alpina, and Ditrichum zonatum, previously known in the north of the Far East only from the Commander Islands, as well as a rare and little-studied species Tortella pseudofragilis. Our record of Bryoerythrophyllum rubrum is the first for Kamchatka.
