    The Arboretum University of Riau constitutes of a secondary forest in Pekanbaru. Many plant genera exist in this Arboretum, therefore the litter produced has high content of cellulosa that may provide suitable environment for many cellulolitic fungus. The purpose of this study was to obtain the cellulolytic fungus isolates by screening the soil that collected from Arboretum University Riau, using Potato Dextrose Agar medium. The selection of cellulolytic fungus used Carboxyl Methyl Cellulose medium and was indicated by the appearance of clear zona. Cellulase activities were determinated using the ratio of clear zone and colony diameter. The result identified 53 cellulolytic fungus isolates. The L4H4 isolate had the highest ratio (3,51). There were three ratio criterions of clear zone to colony diameter in this study, i.e. high (24,53%), medium (35,85%) and low (39,62%). The characterization result showed that 15 fungus isolates belonged to the genera Aspergillus, Penicillium, Paecilomyces, Mucor and 2 isolates were unidentified
