Hey! What’s wrong with my Aspen?

My aspen is really looking sick. It was fine thru July and then started turning black. Would you take a look and let me know what you suggest? It’s definitely not a watering issue.

The leaf blackening is caused by a non lethal fungal leaf disease called marsonina. It is usually a problem seen in the spring, when the weather is wetter and leaf tissue is undefended by its waxy cuticle.  We had a wet late summer in Minneapolis and marsonina grew like crazy.  There are many aspen trees across the city with this mostly unpredictable disease.
