Portuguese. The orchids have a great diversity of genus and species, which contributes to a singular wealth of flowers, that present immense variation of colors and forms. Within the trade of ornamental plants orchids constitute a promising area of agribusiness, with high added value. However, one of the major limitations for the production of these plants is the incidence of diseases, mainly caused by fungi. In this context, the objective of the study was to isolate and identify fungi from orchids with a symptomatological picture of disease of fungal etiology. The incidence of 3 genera of pathogens of fungal etiology in 10 genera of orchids was verified. The causal agent with the highest percentage of frequency was Nigrospora sp.
