Uromyces salsolae Rabenh.

Description
Uredinia on both leaf surfaces, subepidermal, erumpent, round to ellipsoidal, ca. 100 µm, yellow, with a peridium.

Urediniospores globose, subglobose, cylindrical, ellipsoidal or obovoid, yellowish brown, 18‒32 × 16‒20 µm; wall 2‒3 µm thick, finely echinulate, with 4‒8 scattered germ pores.

Telia formed from uredinia on both leaf surfaces, subepidermal, erumpent, brown or black, with a peridium.

Teliospores globose, subglobose or ellipsoidal, apex rounded to papillate, reddish brown, 22‒31 × 19‒25 µm; wall 3.0‒3.5 µm thick at sides, 6‒7 µm thick at apex, smooth, with a persistent pedicel, 55‒145 µm.
