The preliminary results of the classification of moss vegetation in the Forest-Steppe of Ukraine according to the eco-floristic classification based on the Brown-Blanke method are summarized. The classification scheme of the moss vegetation of the investigated region is ordered, which includes 10 classes, 13 orders, 21 alliances, 5 sub-alliances, 47 associations, 34 sub-associations and 21 nonrank groups. It is supplemented by 13 epigeous sinusiums, associated with various types of vegetation and phytocenosis. Epigeous moss vegetation is represented by seven classes (Сеratodonto purpurei-Polytrichеtea piliferi Mohan 1978, Cladonio digitatae-Lepidozietea reptantis Jez. & Vondr. 1962, Psoretea decipientis Matt. ex Follm. 1974, Funarietea hygrometricae v. Hübschm. 1957, Pleurochaeto squarrosae-Abietinelletea abietinae Marst. 2002, Hylocomiеtea splendentis Marst. 1992), seven orders, 11 alliances, two sub-alliances, 17 associations, 16 sub-associations and 10 nonrank groups. Epiphytic briocommunities belong to three classes (Cladonio digitatae-Lepidozietea reptantis Jez. & Vondr. 1962, Neckeretea complanatae Marst. 1986, Frullanio dilatatae-Leucodontetea sciuroidis Mohan 1978 em. Marst. 1985), seven alliances, 21 associations, seven sub-associations and five nonrank groups. Epixylous briocommunities are represented by the class Cladonio digitatae-Lepidozietea reptantis Jez. & Vondr. 1962, three orders, three alliances, three associations, four sub-associations and two nonrank groups. Less often on dead wood, which is in the initial stages of destruction, there are groups belonging to the class Frullanio dilatatae-Leucodontetea sciuroidis Mohan 1978 em. Marst. 1985 and are represented by four associations. On stony substrates (granites, limestones, sandstones, anthropogenic origin) bryocenoses belonging to three classes (Grimmietea alpestris Had. & Vondr. 1962, Schistidietea apocarpi Jez. & Vondr. 1962, Neckeretea complanatae Marst. 1986), three orders of magnitude, four alliances, two sub-alliances, eight associations, three sub-associations and five nonrank groups, were found
