Abstract:
The morphology and ecology of afnew species of the cyanophyte/cyanobacterial genus Aphanizomenon Morren ex Bornet et
Flahault, A. slovenicum Rekar et Hindák, are described from Lake Bled, NW Slovenia. The species produced a heavy water
bloom in May - December 1997 but disappeared during 1998. Macroscopic flakes of bundles of trichomes similar to A. flosaquae
(L.) Ralfs ex Bornet et Flahault formed in a layer between 10 - 20 m depth. They differed from A. flos-aquae by shorter
and narrow short cylindrical to barrel-shaped cells, and by trichomes that sometimes consisted of morphologically different cell
sections. Maximum abundance was found in August : 655 trichomes.ml1. Heterocytes were occasionally present and akinetes
have been observed only in laboratory cultures. The main characteristics of the investigated cultures of A. slovenicum and A.
flos-aquae isolated from a fishpond at Ledava (NE Slovenia) are given
