Coffee, in the provinces of San Ignacio and Jaén, in the Cajamarca region, is the most economically important crop. The objective of this research was to identify the fungi associated with parchment coffee beans, green gold beans and roasted beans. From the warehouses of three exporting companies (Organización Agraria Cafetalera El Diamante, Cooperativa Agraria Cafetalera CASIL LTD and Cooperativa Agraria y de Servicios Unión de Cafetaleros Ecológicos-UNICAFEC). The samples were probability samples of 20 kg of parchment coffee. From these samples, subsamples of 1.0 kg of parchment coffee, 1.0 kg of green gold coffee and 1.0 kg of roasted coffee were selected for fungal isolation. The fungi Aspergillus niger, A. flavus, A. oryzae, A. tamarii, A. fumigatus and Penicillium citrinum were isolated. A. niger had the highest incidence with 76.6 % to 91.2 % in parchment coffee beans and 80 % to 97 % in green gold beans. Other isolated species were Chaetomium globosum, Neurospora tetrasperma and Rhizopus delemar in percentages of 0.0 to 4.2 %, 0.0 to 3.0 % and 0.0 to 1.6 %, respectively. No fungi developed on roasted coffee beans
