Diagnostic Notes
Sori surrounding all peduncles of inflorescences with rudimentary spikelets, cylindrical, often curved, 5–20 mm long, 2–3 mm wide, at first covered by a thick white peridium that later ruptures irregularly exposing a black agglutinated spore mass with a powdery surface.

Spores solitary, globose, subglobose or broadly ellipsoidal, (11–) 12–16 (–17) × (9–) 10–15 µm, laterally slightly flattened, 8–12 µm wide, light reddish brown, without appendages; wall 0.5–1.0 µm thick, covered by irregular coarse warts and ridges that are often connected by small transverse ridges or warts.

Spore germination resulting in phragmobasidia; cells separating readily, producing ellipsoidal basidiospores.
