ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGAR1C1 Tomus 65. Budapest 1973. Green Snow from Haswel Island (Antarctica) By E. KOL, Budapest Abstract — The species Chlorella antnrctica (FRITSCH) WILLE, Pleurochloris anomala var. antarctica KOL, and Chlorosphaera antarctica FRITSCH predominate in the green snow from Haswel Island. Various green Cryoseston types were also observed in t he Antarctica. As far as I know, no coloured snow was hitherto observed inland on the Antartica. On its periphery, however, red, green and yellow cryosestons are frequently encountered. The algal community of these coloured snows is highly different. I propose to discuss in the present paper chiefly the algae of the green snow on Hasw 7 ell Island. K. VISY, Hungarian meteorologist observed several square meters of green snow 7 on the more than 10 cm thick snow cover of Haswel Island. Snow samples, collections VISY'S collections derive from 6-12 January, 1972, and are grouped as follows: 1. green snow from Haswel Island ; 2. green snow, same locality; 3. crumbling rocks, same locality; 4. penguin guano, same locality; 5. live material from snow, same locality; 6. dried moss, same locality; 7. Mac Mahon, near nests of penguins. Requested by K. VISY, A. PIASEK, Polish meteorologist, collected the following snow samples: 1. Mac Mahon, penguins, path to sea (snow), 28 Dec, 1971; 2. Mac Mahon, near nests of penguins, 28 Dec, 1971; (dry material); 3. Opastna Bay Motodiornaya, 21 Jan., 1972; 4. Snow on ice in sea, 100 m from shore, 4 Jan., 1972. 1 am greatly indebted to both scientists for the collections. Even the smallest snow sample from the Antarctica represents great scientific value. These collections are rendered even more interesting by the fact that I received on my request not only preserved but also dry live material which, when brought into culture, revealed also the different developmental stages of some algal species. On the green snow of Haswel Island From the Haswel Island, E. TITKOS, Hungarian meteorologist, was the first to bring snow and soil samples in 1966; several algal species were then successfully cultured from them (KOL 1968a). In 1972, K. VISY, Hungarian meteorologist, saw green snow on Haswel Island, and brought home both preserved and dried samples. According to the Table, the species Chlorella antarctica (FRITSCH) WILLE (Figs. 1-8) and Pleurochloris anomala var. antarctica KOL (Figs. 14-17) predominate, in the green snow of Haswel Island. In smaller to greater numbers, the following algal species could also be shown from the snow samlpes : Chlorosphaera antarctica FRITSCH (Figs. 18-20), Prasiola crispa (LIGHTF.) MENEGH. (Fig. 24), young plant; Scotiella nivalis (SHUTTLEW.) FRITSCH, Sphaerocystis schroeteri var. Ann. Hist.-nat. Mus. Nat. Hun;/., 1973, 65
