In this paper, we describe an unusual vernal bloom of Dinobryon sociale EHRENB. (Chrysophyta, Chrysomonadales) in the plankton of Lake Balaton, Hungary, in 1993. The event was aberrant for two reasons, both of which would have appealed to the scientific curiosity of our late colleague, Pál Juhász-Nagy: one is that the alga seems ecologically unsuited to the environmental characteristics of Balaton and, indeed, has been recorded hitherto only sporadically. The second is that the 1993 bloom had a very localized origin ? a near shore area subject to dredging opeartions ? and the rapid growth of the inoculum did much to perpetuate a trongly patchy distribution with respect to the dispersion of the species in the whole eastern lake area. The observations are relevant to the perception and evaluation of patchy distributions and to the importance of measuring them at the appropriate spatial and temporal scales. They also raise once again important conceptual questions about the maintenance of species richness, diversity and rarity.
