SILICA-SCALED CHRYSOPHYTES FROM PERMANENT AND TEMPORARY WATERS OF HORTOBAGY, EASTERN HUNGARY

The silica-scaled flagellate flora of permanent (reservoirs, fishponds ) and temporary (roadside Caricetum) waters of the Hortobagy National Park, eastern Hungary, was studied based on materials collected in sum mer 1995 and spring 1996. Altogether, twenty-six taxa were identified in TEM studies: two belong to Chrysophyceae (Chrysosphaerella brevispi na, Paraphysomonas vestita) and twenty-four to the Synurophyceae of wh ich eighteen Mallomonas (M. acaroides, M. akrokomos, M. alpina, M. ann ulata, M. areolata, M. calceolus, M. caudata, M. corymbosa, M. crassis quama, M. cyathellata, M. elongata, M. heterospina, M. intermedia, M. paxillata, M. portae-ferreae, M. punctifera, M. teilingii and M. tonsu rata) and six Synura (S. curtispina, S. petersenii var. petersenii, S. petersenii var. glabra, S. spinosa, S. splendida and S. uvella).
