The 24 strains of anamorphic fungi were isolated from plots which applied urea 11 months ago, in the forest of Pinus dalatensis at Bidoup - Nui Ba National Park, Lam Dong Province, Vietnam. Based on morphology, isolated strains were identified as Aspergillus, Penicillium, Trichoderma and Acremonium. All of them had ability of cellulose decomposition when cultured on Czapek-Dox agar added carboxymethyl cellulose (CMC). Some strains showed a high cellulose decomposition. The effect of nitrate-nitrogen concentration on their mycelia growth were also demonstrated. Most of the highest dry biomass of mycelia were obtained when cultivated with 13g/L nitrate-nitrogen concentration. Some strains tolerated to nitrate-nitrogen concentration of 13g/L in medium.
