A fungus causing a destructive rot was isolated from mung bean sprouts. Symptoms first appeared as small pink to orange spots on the cotyledons or hypocotyl. Under the moist conditions required for sprouting, the sprouts became slimy and gray. Inoculation with a high spore concentration (4.6 × 10^{5/ml) induced 94% decayed sprouts, whereas decreasing concentrations caused progressively less decay. The test fungus was reisolated from lesions on the sprouts. The fungus was tentatively identified as Cylindrocephalum sp.}
