Soil fungi play important roles in ecosystems and these populations are closely related to soil type, climatic characteristics, other microorganisms and plant communities. People’s activities, mainly agriculture alter their habitat and therefore affect fungi diversity and functions on soil. The effects of soil use type (TUS), native vegetation type (TVN) and crop type (TC) on colony forming units (CFU), number of spe-cies and physical, chemical and biological parameters was assessments in the present work in Plurination-al State of Bolivian´s highland agroecosystem. In addition, the diversity and number of filamentous fungi were related to physical and chemical soil parameters (pH, texture, organic matter), The fungi were de-scribed macro- and microscopically and were taxonomically identified. The TUS, TVN and TC influenced differently on the pH, soil texture and soil organic matter (SOM). The TUS and TC significantly affected the CFU´s and number of species. CFU´s were high in crop potato and number of species in Trifolium sp., 44 species were isolated, predominating genera of Penicillium and Alternaria. The rela-tionships between SOM were non-significant and weak (r2 = 32.1, p> 0.05), pH, significant and strong positive relation (r2 = 47.7, p <0.05) and soil texture vs CFU´s no significant and unrelated (r2 = 8.6, p> 0.05). The results suggest that the soil use type affect in soil properties, plant diversity and community fungi. Additionally, it is necessary to investigate other parameters that influence the microbial community in the agroecosystem.
