    Just discovered discolored, distorted berries and spotted leaves on my 4 year old serviceberry (Amelanchier laevis). The berries are swollen 5-6 times normal size and yellow, or orange with a crusty covering. The leaves have orange spots that are swollen on the underside. About one leaf/bad berry per branch. Any help identifying would be great. Otherwise we have a healthy garden, although pear trellis rust appeared in a small way two years ago on my pear tree, but hasn't returned.
    Thank you.

    Probably rust.

    Good Morning Frith,
    Ron is correct. It's the Juniper-saskatoon rust. The disease alternates between junipers and saskatoon, Hawthorn are similarly affected.
    Peace
