It may be Anthracnose. Anthracnose is mainly a seed-borne disease caused by a fungus which has a wide host range on many legume species. This disease can cause serious losses in bean crops in temperate and subtropical zones. Anthracnose is caused by Colletotrichum spp. Mycelium and spores were observed under foldscope.
