Uromyces lapponicus Lagerhein, 1890
no host plant alternation; no uredinia. Spermogonia epiphyllous. Aecia hypophyllous, covering a large part of the leaf, cupulate, yellow; peridium frayed. Telia brown, hypophyllous, pulverulent, often on rachis and petiole. Teliospores one-celled, thin-walled with a low apical papilla and a short hyaline, deciduous pedicel. Fresh teliospores are smooth, but dried ones clearly are verrucose, the warts especially apically in short rows. The length of the spores is (19)21-25(30) µm. The fungus is systemic and hibernates in the below-ground parts of the plant; infected plants look pale and diseased.
Fabaceae, narrowly oligophagous
species with an alpine distribution.
