Gnomonia leptostyla, more commonly known as Sycamore Anthracnose, is a fungal disease among a variety of sycamore trees this time of year. The spring rain enables Sycamore Anthracnose to germinate and penetrate the leaves making the appearance of the tree quite unsightly. Though it rarely results in death, the disease creates the illusion of killing the sycamore by the curling of new shoots, cankers on twigs, brown lesions on leaves (see photo), and twig dieback. Fortunately, this is easily treatable!
