Farkasfa 2. Ördög-tó (basin/floodplain fen, pH = 5): Sphagnum fal lax, 1994.07.28. Grajka-patak (no pH data is available): Sphagnum angustifolium, S.fallax, S. obtusum, summer of 1993; 5. angustifolium, 31.03.1994; S. subsecundum, 21.07.1994. Szakonyfalvi-patak (no pH data is available): Sphagnum fallax, S. obtusum, 20.09.1993; S. subsecundum, 04.09.1994. Felsó'szölnök (no pH data is available): Sphagnum angustifolium, 25.07.1994. RESULTS Altogether 97 diatom taxa were identified during the study (Table 1). Species composition of diatom assemblages was similar to that seen in other peat bogs' diatom studies, with the highest species diversity in Eunotia (15 species and 2 varietas) and Pinnularia (13 species and 3 varietas). They occurred in every sample location, however they were not dominant in each. As is typical of periodically drying up aerophytic habitats such aerophytic diatoms as Pinnularia borealis, Hantzschia amphioxys, Adlafia bryophila, and Mayamaea fossalis were present in some localities (mainly Nyíres-tó, Nyírjes-tó, Gajka-patak, Szakonyfalvi-patak). • others ED Gomphonema clavatum 51 Kobayasiella subtilissima • Lemnicola hungarica El Adlafia bryophila H Eunotia lapponica • Eunotia steineckei ü Eunotia exigua E3 Eunotia bilunaris var. mucophila El Chamaepinnularia mediocris • Eunotia paludosa Fig. 2.
