gall

Uredinia on the leaves and leaf sheaths, reddish brown, in large confluent groups; urediniospores echinulate, with 3 pores, on a long pedicel. Telia like the uredinia, but blackish brown. Teliospores two-celled, slender-pyriform; wall smooth, apically thickened, no papilla. Pedicel to over 200 µm, persistent, hyaline, often attached obliquely.

uredinia, telia

Poaceae, monophagous

Phragmites australis & subsp. chrysanthus (Arundo isiaca).

synonyms

P. obtusata Otth, 1898; Puccinia trabutii Roumeguère & Saccardo, 1881.

notes

species of southern Europe. Conspicuous by its brightly white aecia. On common reed confusion is possible with P. magnusiana, but the pedicels of the teliospores are much longer and hyaline.
