Abstract: This report discusses the occurrence of the cyanobacterium species Aphanothece stagnina in Lake Velence. Besides the report summarised here, earlier occurrences of this species in Hungary are also presented in this article. Easily observed and well visible to the naked eye, this cyanobacterium was found in the sediments of "Lángi-" and "Német-tisztás" as well as in the phytoplankton of "Német-tisztás". It has probably lived in the lake for decades but only appears from time to time. Observations on its presence and occurrence have been a contribution to the assessment of the biological diversity of the mosaic-like Lake Velence. Although the sediment of the lake has been well studied from 1989, this species was only detected in 1997. Its multiplication and growing distribution may well be connected with the growing biological uniformity of the lake. Further studies of Aphanothece stagnina in the lake may be an ideal tool for the biomonitoring of this precious lake.
