 Abstract-Microfungi of the rhizosphere and rhizosplane of dominant plants of Wady Shagra was investigated. The valley comprises three main zones, each with characteristic vegetation.Twenty-nine species of rhizosphere fungi (Mitosporic fungi, 25 spp; Zygomycota, 3 spp.; Ascomycota, 1 sp.) were isolated on Czapek-Dox medium (in sea water) with sucrose replaced by glucose, xylan, cellulose, starch and tannin. Higher counts were detected on glucose, xylan and cellulose agar, and lower count on tannin agar. The number of species has been increased gradually from zone 1 to zone 3 accompanied with more total counts and improvement of soil conditions. P. chrysogenum,  Aspergillus carneus, Cladosporium cladosporoides, A. sulphureus and Scopulariopsis brevicaulis were isolated regularly. The isolated fungi were commonly xerotolerant. Correspondence statistical analysis indicated that many fungi were found associated to particular plants. Widespread species were also present. The biodiversity of isolated fungi has been influenced to certain degrees by the edaphic characteristics.
