''Botrytis fabae'' is a plant pathogen, a fungus that causes chocolate spot disease of broad or fava bean plants, ''Vicia faba''. It was described scientifically by Mexican-born Galician microbiologist Juan Rodríguez Sardiña in 1929.〔 == Symptoms == Chocolate spot disease caused by ''Botrytis fabae'' manifests itself as small red-brown spots on leaves, stems and flowers of broad bean plants. These enlarge and develop a grey, dead centre with a reddish-brown margin. Spores form on the dead tissue and spread the infection to other plants. In severe infections leaves and flowers may fall and badly affected stems may keel over.〔(Government of Western Australia )〕
