uredinia minute, up to 0.2 mm, pustulate, at first long covered by the epidermis, later by an peridium with a centrale pore; spores orange yellow when fresh, 18-31 x 13-21 µm, minutely echinulate. Telia at the underside of fallen leaves, small brown crusts; spores intra-epidermal.

notes

The mycelium hibernates in the leaves of Vaccinium, making new uredinia in spring; a population therefore can maintain itself without host alternation.
