no alternation of host plant. Spermogonia near the aecia, between epidermis and cuticula. Aecia amphigenous, orange, without a peridium but with a circle of hyaline, sausage-shaped curved paraphyses; spores produced in chains, densely verrucose. Uredinia hypophyllous, yellow, small, 0.2 mm, equally encircled by paraphyses, spores single, pedicellate. Telia hypophyllous black; spores short pedicellate, elliptic, brown, transversely divided into c. 4, finely verrucose cells, apically terminated by an ill-defined apiculus.

host plants

Rosaceae, narrowly oligophagous

Marcetella moquiniana, Sanguisorba minor & subsp. balearica, officinalis, rupicola, verrucosa; Sarcopoterium spinosum.

Erdoğdu, Hüseyin & Suludere cite as host: Sanguisorba spec. and Rubus sanctus; probably there is some confusion involved.

synonyms
