Gönczöl, János; Révay, Ágnes: Aquatic Hyphomycetes in a tributary of the Morgó stream, Börzsöny Mts, NE Hungary

Table 4. Similarity comparisons of the fungal spora found in the Csömöle stream and at six sampling sites of the Morgó stream. Upper number: similarity values, in %, based on S0rensen's index; lower number, in brackets: similarity values based on Kendall's index. Morgó sti earn Site I Site II Site III Site IV Site V Site VI Csömöle stream 69.88 70.23 80.00 78.35 80.89 80.00 (22.85) (45.01) (28.09) (32.36) (34.27) (42.86) The highest number of conidia (23688/1) encountered in this study was more than twofold of the highest value (10926/1) obtained earlier in the main channel (GÖNCZÖL et al. 1999). The surprisingly low conidial concentrations in October and the strikingly high concentrations in December differ from the 5 Alatospora a. D Anguillospora 1. • Anguillospora sp. 1 • Clavariopsis a.
