Abstract
In June 2006, a large number of small black spots containing a branching network of black hyphae developed on shipped Satsuma mandarin fruits grown in greenhouses, which markedly decreased their commercial value. The fungus that was frequently isolated from the damaged fruits was identified as Cladosporium cladosporioides. Inoculation of fruits with the fungus caused the same symptoms, and the fungus was reisolated from the diseased fruits. The disease caused by this fungus has not been previously documented in citrus fruits; we name this new disease “sooty spot” on the basis of its symptoms.
