Abstract
in order to monitor the growth of the Black Sea coastal mycoplankton
in eutrophication conditions, in 1990 there were drawned biological
samples of fresh sea water at three station networks: the fixed
station Mamaia, five stations eastern to Constantza at 1-30 Mm from
the coast; four stations in front of the localities Portita, Chituc,
Midia and Constantza and three stations in front of the Danube 
mouths. The ecologic group of the yeast fungi was dominant in the
structure of the fungus flora in all zones, exceeding 80% of the
whole spore production, due to the species Rhodotorula glutinis and
Candida diddensii. The colonies of Cladosporium sp. and Penicillium 
sp. together with the above mentioned species have produced big
fungus blooms. A number of 39 taxa belonging to the classes 
Phycomycetes and Deuteromycetes were determined. Concerning the
seasonal distribution, in spring and summer the orders Hyphomycetes 
and Blastomycetes were dominant by the species Cladosporium and 
Candida. In autumn the families Cryptococcaceae and Dematiaceae  
were dominant in the micromycete populations.
