Abstract

Sixty-nine species and four varieties which belong to twenty eight genera of terrestrial fungi were recovered from polluted and nonpolluted water and mud samples on glucose and cellulose-Czapek's agar at 28ËšC. The most common species from the two substrates on the two types of media were Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Cladosporium cladosporioides, Fusarium oxysporum, Mycosphaerella tassiana and Penicillium chrysogenum. Twenty-six species belonging to 14 genera were isolated from polluted (26 species and 14 genera) and nonpolluted (17 and 10) mud samples on sabouraud’s dextrose agar at 28°C. The most prevalent species were Acremonium retiulum, Alternaria alternata, A. flavus, Aphanoascus fulvescens, Aspergillus terreus, Aphanoascus sp., Penicillium funiculosum and Stachybotrys chartarum.
