    Hi All,

    I have a young Canadian Red Maple (Acer Rumrum?). When the nursery delivered and planted it, I noticed that there were black markings forming on the leaves. The same thing happened the season after. Can you please have a look at the attached picture and let me know what you think it is?

    Thanks.
