“…All found that at least some species were more abundant during some times of the year than others. Cooke (1954), Dick and Newby (1961), Roberts (1963), and others working in temperate zones have found greater species diversity and frequency of occurrence during spring and fall.…”

“…In situ baiting is incon venient if many sites are being studied, because it is necessary to return to each site to collect the containers. For these reasons, many workers have chosen to collect water and soil samples and bait them in the laboratory , Wolf 1944, Coker 1923, Harvey 1942, Alabi 1971a,b, Dayal and Thakur Ji 1966, Dick and Newby 1961, Roberts 1963.…”

“…Since Coker's (1923) initial observations, several studies on seasonal periodicity have been carried out (Roberts 1963, Dick and Newby 1961, Hughes 1962, Ziegler 1958, Dick 1963, Alabi 1971a,b, Dayal and Thakur Ji 1966, Dayal and Tandon 1962, Cooke 1954, Rooney and McKnight 1972.

“…Some members of the Saprolegniaceae reportedly display a distinct seasonal occurrence (Coker 1923, Hughes 1962, Dick and Newby 1961, Roberts 1963, Alabi 1971a. The field study was designed to investi gate this ecological aspect of the family by repeatedly sampling several aquatic sites for two years.…”

Twenty-six identified and three unidentified species belonging to eight genera of zoosporic fungi were recovered from seventy-six mud samples of Egyptian lakes using sesame seeds as baits. Nineteen samples were collected along the borders of four major lakes. Pythium, Phytophthora and Allomyces, yielded the highest spectra of zoosporic species, while Aqualinderella, Blastocladia and Dictyuchus, had one species. Pythium, Aphanomyces, Allomyces, Aqualinderella, Phytophthora and Saprolegnia were the dominant zoosporic genera while Blastocladia and Dictyuchus were rare. The most prevalent species of zoosporic fungi were Aqualinderella fermentans, Aphanomyces laevis and unidentified Pythium species while the other isolated species in this study were rare. Menzalah was the richest lake with zoosporic species followed by Borolous and Karoon. Some zoosporic fungal genera were recovered from the mud of the four tested lakes (participator genera) and others from three lakes or from only two lakes. Physicochemical characteristics of the mud samples (pH, total soluble salts and organic matter) revealed no correlation with the fungal occurrence and distribution in these lakes.

One hundred and eleven identified and seven unidentified species in addition to 5 varieties belonging to forty-three aquatic fungal genera were recovered from 452 soil samples collected randomly from different localities in Nile Delta and Suez canal regions including eleven governorates. The investigated soil samples were collected seasonally during the period from autumn 1990 to summer 1991 (1 13 samples each season). The richest season (85 identified and 5 unidentified species in addition to 2 varieties) in aquatic fungi was the winter season (10.0-15.5 "C) whereas the poorest (32 identified and 5 unidentified species in addition to one variety) was summer (24.0-27.5 "C). The richest soil samples in aquatic fungi were those of low or moderate temperature seasons, high contents of organic matter and considerably poor in total soluble salts. The pH value did not show any regular seasonal variation and did not exhibit any considerable influence on fungal populations. Some aquatic fungal genera and species were disappeared completely in certain seasons and vice versa.The most dominant aquatic fungal genera were Pythium, Allomyces, Aqualinderella and Nowakowskiella. The commonest aquatic fungal species were Allomyces anomalus, Aqualinderella fermentans, Nowakowskiella elegans, Blastocladiopsis parva and Dictyuchus sterilis.The seasonal fluctuations of aquatic fungi were followed in various parts of the world (e.g.
