Camellia Leaf Gall

Exobasidium camelliae is a phytopathagenic fungus that infects ornamental shrubs of the Camellia genus. It absorbs nutrients from the host through its haustoria and causes the leaves of the host plant to be thicker and lighter green than usual. It forms a hymenium between cells four to six layers above the lower epidermis which is subsequently sloughed off to reveal its basidia.
