Peanut Sclerotium infects almost all plants except field crops such as corn, sorghum, wheat and oats. Infected plants wilt and die. Low growing ornamentals are particularly susceptible such as Ajuga where the whole plant may turn black and die quickly. Woody ornamentals like Aucuba will rot at the crown and then die back or topple over.
Sclerotium lacks fruiting structures and spores.
The white hyphae is often diagnostic of the fungus.
