Abstract
Calonectria crotalariae comb. nov. is designated as the causal agent of an apparently unreported disease of peanuts in southwest Georgia. Disease symptoms include chlorosis, wilting, and blackening and necrosis of pegs, pods, and roots. Perithecia of the fungus are orange to red, subglobose to oval or obovate, and 320-465 high and 290-370 wide. Asci are hyaline, clavate, long-stalked, and thin-walled, contain eight ascospores, and measure 95-138 x 13-19 Ascospores are hyaline, granular, fusoid to falcate, one to three septate, slightly constricted at the median septum, and measure 34-58 x 6.3-7.8 The imperfect stage, Cylindrocladium crotalariae, is characterized by dichotomously and trichotomously branched conidiophores arising laterally from a main central axis that terminates in ? hyaline, globose swelling measuring 6-13 in diam. Conidia are hyaline, granular, cylindric, mostly one to three septate, and measure 58-107 x 4.6-7.1 The fungus is pathogenic to leaves of Crotalaria spectabilis, to six species of Eucalyptus, and to leaves, pegs, pods, and roots of Arachis hypogaea
