Abstract
This paper includes references to the data obtained in 1989 regarding
the structure and distribution of the coastal marine mycoplankton. 
The researches used fresh sea water collected from the following 
sectors: a fixed station located in front of Constantza town; a
network of five stations eastern to Constantza town; in front of
the localities Portita, Chituc, Midia and Constantza as well as at
the Danube mouths. The share of the main taxonomic and ecological
groups has oscillated from one sector to another, depending on the
environmental factors. Thus the domination of the yeast fungi for
all the working periods was a general characteristic of the whole
marine mycoflora. The domination of the yeast fungus group was due
to the potentially pathogentic forms Rhodotorula sp., Candida sp. and
Geotrichum sp. There have been found 37 taxa belonging to the eco-
logical groups of yeast and filamentous fungi, the most frequent 
being the families Cryptococcaceae and Moniliaceae. The family
Tuberculariaceae represented only 13% of the whole mycoplankton.
