no host alternation. Spermogonia, aecia, uredinia, and telia all amphigenous. Spermogonia between the aecia. Aecia white, in circles. Uredinia up to 10 mm, yellow to orange, long covered by the epidermis, with a variable number of paraphyses. Telia small, long covered by the lead grey epidermis, finally black and naked. Around the telium, to a lesser degree also within, often there are many dark brown paraphyses; they are apically fused, forming a protective layer around the telium. Spores 1-2 celled, on an up to 30 µm long, deciduous pedicel. The percentage of one-celled teliospores is variable.

notes
several authors feel that P. alli, as diagnosed above, does not form a natural entity. In particular Klenke & Scholler distinguish three species: A – telia with paraphyses: P. allii; B – telia without paraphyses; B1 – urediniospores with 10-12 pores: P. mixta; B2 – urediniospores with 12-15 pores: U. ambiguus. In the latter two species the percentage of one-celled teliospores is high and very high, respectively.
