Ecological Study of Fungi in the Mud –Flats of Tigris Edges in Baghdad

Abstract

In the present study, fungal flora of the uncolonized mud of Tigris edges was investigated . Known isolation techniques ,based on different concepts were used in a trail to distinguish between genera present in the active vegetative phase and others existing in the dormant spore phase . According to the frequency of isolation, the fungi reported are classified into 4 groups showing different existence patterns. Group (A) fungi, comprised genera and species that most probably occur in the active vegetative phase .Genera assigned to this group are: Fusarium ,Acremonium,Penicillium ,Mucor and Rhizopus. Fungi of group (B) which are Penicillium, Aspergillus, Alternaria and Ulocladium. occur partly in the active vegetative phase and partly in the dormant spore phase whilst members of groups (C)which include Aspergillus amstelodami only and (D) accommodate species with no particular trend, most likely exist only in the spore phase.
