Botrytis cinerea is an important plant pathogen that can infect a wide range of hosts and cause serious losses many crops. In Orchidaceae, gray mold is one of the main diseases caused by fungi, commonly associated to flower spots. Here, we described a new disease caused by B. cinerea on Maxillaria richi, an orchid native from Ecuador and marketed in Brazil. Samples of M. richii with unusual defoliation symptoms were observed in greenhouse. The diseased material was used to isolate the pathogen. The morphological and molecular data revealed that the isolates belong to B. cinerea. The pathogenicity test confirmed that B. cinerea is the etiological agent of the defoliation. To our knowledge, this is the first report of B. cinerea causing basal leaf rot and defoliation on a member of Orchidaceae.
