Maravalia limoniformis McTaggart, Ono, Berndt & R.G. Shivas

Description
Uredinia on chlorotic leaf spots, often scattered over the entire lower leaf surface, subepidermal, erumpent, round, ca. 250 µm diam., pale yellow; paraphyses peripheral, dense, cylindrical, clavate or strongly incurved, subhyaline to golden with stratified layers, 25‒60 µm high (from base to apex) × ca. 7‒10 µm wide.

Urediniospores short pedicellate, globose, obovoid, ellipsoidal or pyriform, subhyaline to very pale yellow, 18‒25(‒30) × 16‒18 µm; wall even 1.0‒1.5 µm thick, echinulate, spines 1.0‒1.5 μm apart, germ pores not seen.

Telia similar to and replacing uredinia.

Teliospores short-pedicellate, one-celled, obpyriform, ovoid, ellipsoidal or lemon shaped, often with papillate apex, 26‒38 µm × (10‒)12‒22 µm, hyaline smooth and thin-walled; pedicels fragile, hyaline, 5‒15 µm long × 3‒6 μm wide at point of spore attachment, mature spores often have remnants of the pedicel attached at the base.

Basidia formed by apical elongation of teliospores, up to 90 µm long.

Basidiospores globose, ca. 10 µm diam.
