Kol, E.: Snow algae from the valley of the Morskie Oko Lake in the High Tatra

Koliella tatrae var. fogarasensis (KOL) HINDÁK (Plate I, Figs. 16—21, 31,32) Fusiform, 1—2 u, wide, 20—50 u. long cells of different curvature and with elongately pointed ends (Fig. 21). Figs. 16, 17 show a dividing cell, Figs. 18—20 demonstrate cells separated during division, with one blunt end. Abnormal division is shown on Figs. 31, 32. I described this microorganism from the Fogaras Alps and the Retyezát massif of the South Carpathians (KOL, 1949 a), where it caused a green snow bloom. It was now found also in the High Tatra. Baphidonema brevirostre SCHERFFEL (Plate I, Fig. 22) The filament, 3 u. wide and consisting of 4—8 cells, is straight or slightly bent. SCHERFFEL described it (1910) from the snow of the Great Papyrus valley of the High Tatra, Since then, it was found on diverse snow surfaces of not only Europe, but also on the snows of other continents. Characteristically, the plant never occurs in great individual numbers. Baphidonema nivale LAGERH. (Plate I, Figs. 1-5) Long: 1.5—2 a. wide filaments of various curvatures, consisting of 4—8 cells. The species is one of the most widely dispersed cryobionts on earth. It was found in numerous places in the High Tatra ; Késmárk Green Lake valley, 1680 m a.s.l., Dolina Kepy, 1140 m .a.s.l., Blue Lake valley, 1900 m a.s.l. (KOL, 1928), and several other localities. Baphidonema sabaudnm f. tatrica forma nova (Plate I, Figs. 9,10) 1.5—2 u. wide, semicircular filaments, consisting of 8—32 cells. I described the species Raphidonema sabaudum KOL from the green snow of the Mont Blanc (KOL, 1934) ; the plant of the High Tatra is thinner and considerably more curved, differing in these characteristics from the nominate form. Raphidonema sabaudum KOL f. tatrica forma nova Tabula I, Fig. 9, 10) Differt a typo in forma curvatorum filamentorum. Stichococcus nivalis CHODAT (Plate I, Fig. 29) 6 [i wide, 12 \i long, cylindrical cells. The species is one of the most widely distributed snow inhabiting algae. Cyanophyta Romeria cryophyla sp. nova (Plate I, Figs. 25, 26, 34, 35) Straight or curved filaments, singly, consisting of 8—16 cells (Figs. 34, 35). Filaments 1 —1.5 u. wide, without gelatinous sheath, 3 u. with sheath, 20—40 u. long. Cells bluish green, as long as wide, or twice as long (Figs. 25, 26). Occasionally several
