Twenty-one strains isolated, cellulose decomposing fungi, were identified on the basis of morphological, physiological and biochemical properties as Acremonium sp., Aspergillus sp., Chaetomium sp., Chrysonilla sp., Doratomyces sp., Fusarium sp., Gliomastix sp., Penicillium sp., Trichoderma sp., Varicosporium sp. and Verticillium sp.. The optimum tempeture for growth was in the range of $20-30^{circ}C$. Most of the isolated stains utilized all tested carbon sources, and scarcely utilized urea as a nitrogen source. Only the strain No.2 had high activity of cellulase.
