Herbarium (IMAGE) Max-Planck-Gesellschaft Caption This is a potato specimen from the Kew Garden herbarium, collected in 1847, during the height of the Irish famine. The legend reads "Botrytis infestans", because it was not known yet that Phytophthora does not belong to the mildew causing Botrytis fungi.
