SUMMARY
Spermogonia: in small clusters, amphigenous, honey-coloured or orange-red [Wilson & Henderson 1966].
Aecia: usually epiphyllous, sometimes on yellowish spots, often confluent in concentric rings around the spermogonia, cinnamon-brown, pulverulent. Aeciospores 22-30 x 16-28 µm, subgobose to broadly ellipsoidal, brown, the wall echinulate, 2-2.5 µm thick, with three equatorial pores [Wilson & Henderson 1966].
Uredinia: usually hypophyllous, minute, pulverulent, brown. Urediniospores 26-28 x 23-25 µm (only a few measured), morphologically very similar to the aeciospores.
Telia: mostly hypophyllous, small, scattered or confluent in small groups, pulverulent, blackish brown. Teliospores (27-) 30-34 x 17-21 µm [24-50 x 16-27 µm fide Wilson & Henderson 1966], ellipsoidal to cylindric-ellipsoidal, rarely obovoid or angular, chestnut brown, hardly constricted at the ± median septum, the wall faintly verruculose, pore of the upper cell almost apical, of the lower cell towards the septum. Pedicels hyaline, slender, to 40 µm long, deciduous, sometimes eccentrically attached.
