Big rosette type brown-spot was found on tea (Camellia sinensis (L)O.Kuntze) leaves in 2013 and 2014. Fungi isolated from the diseased plants were identified as the Colletotrichum gloeosporioides species complex. Inoculation tests confirmed that this fungus was the causal agent of the disease. Big rosette brown-spot symptom is a special symptom of brown-blight disease on tea.
