Puccinia erythropus

Spermogonia sub-epidermal, mostly sub-globose, 80-110 x 85-120 µm. Aecia aecidioid, surrounded by a well-developed peridium;aeciospores formed in chains, mostly sub-globose to broadly ellipsoid, 17-25 x 15-22 µm, walls 1 µm thick, uniformly verrucose, no germ pore. Uredinia on abaxial leaf surface, cinnamon-brown;urediniospores broadly ellipsoid to obovoid-ellipsoid, 24-35 x 18-23 µm, walls 2-3 µm thick at sides, usually 4-8 µm thick apically, cinnamon-brown or chestnut-brown, uniformly echinulate, 3-4 obscure equatorial germ pores. Telia on abaxial surface, often confluent, early exposed, pulverulent, blackish-brown;teliospores broadly ellipsoid, obovoid-ellipsoid or oblong-ellipsoid, rounded at both ends, moderately constricted at septum, 28-52 x 14-24 µm, walls 1.5-2.5 µm thick at sides, 3-8 µm apically, chestnut-brown, pedicels hyaline, thick-walled, not collapsing, to 80–140 µm long, two-celled. See Ono and Azbukina (1997) for a more detailed description.
