filaments in one group (Fig. 34). Filaments surrounded by about 1 u, wide, yellowish gelatinous sheath. Septum occasionally hardly discernible. This microorganism stands nearest to Bomeria elegáns WOLOSZYNSKA, but differs in a. the shape of the filament, b. the yellow colour of the gelationous sheath, c. the shorter cells, and d. being a cryophilous species. Romeria cryophyla sp. nova (Tab. I, Fig. 25, 26, 34, 35) Filamenta solitaria, plusminusve recta vel curvata, 20—40 JJ, longa, 3 \i crassa. Vagina gelationosa hyalina et lutea modice ampla, 1 —1.5 JJL crassa. Trichomata 1—1.5 u crassa cellulis semel vel bis longioribus quam latis. Protoplasta coeruleo-viridia ut homogenea viditur. Habit.: in nive alpina Tatraensium, in volle laci Morkie Oko, 1500 m.s.m. Fungi (Monaster bicornis KOL (Plate I, Fig. 27) I described the species from the snow fields of Alaska (KOL, 1941). SIEMINSKA (1956) reported it for the first time from the Tatra; she found it at 2000 m a.s.l., on the Mienguszowiecki Cirque. Chionaster nivalis (BOHL.) WILLE (Plate I, Fig. 24) This snow fungus, called the snow star, was found not only in Europe, but also in numerous cryobiotops of the Northern Hemisphere. Frequent in the Tatra, the plant is to be found in diverse coloured snows, but never in masses. Summary In the snow samples, collected in the valley of the Morskie Oko Lake at 1500 m a.s.l., I found the following microorganismal community: of 23 different microorganisms, 15 species were Chlorophytes (12 cryobionts and 3 cryoxens), 4 Cyanophytes (1 cryobiont and 3 cryoxens), 3 Fungi (2 cryobionts and 1 cryoxen), and one cryobiont Chlorobacterium. Endemic for the High Tatra of these microorganisms are: Ankistrodesmus longissimus var. Rostafinskii KOL, Chlamydomonas Rostafinskii STARMACH-KAWECKA, Carteria nivale var. minor KOL, Györffyella tatrica, KOL, Raphidonema sabaudum f. tatrica KOL, Romeria cryophila KOL. The snow vegetation of the High Tatra belongs to the III, or upper cryovegetation-type, the snow alga community consisting mainly of cryobiont species. The following new microorganisms were found in the valley of the Morskie Oko Lake: Carteria nivale KOL var. minor var. nova (Plate I, Figs. 6—8), Raphidonema sabaudum KOL f. tatrica forma nova (Plate I, Figs. 9, 10), Romeria cryophila sp. nova (Plate I, Figs. 25, 26, 34, 35).
