Diagnostic Notes
Sori in different parts of the host plant, usually restricted to 1 or several heads (spikes) of an inflorescence (occasionally only part of a head is affected), naked, globose, 1–2 mm diam., black, compact with a powdery surface; sometimes developing in the basal parts of stems, forming fusiform swellings 3–15 mm long and 1.0–1.5 mm wide, covered initially by remnants of green host tissues and whitish fungal elements. In the spikes, sori initially developing in the floral axis, eventually destroying the flowers. Immature sori covered by a thin whitish or pale brown peridium formed of host and fungal tissues, also hidden by the many bracts in a head.

Spores globose or subglobose, rarely broadly ellipsoidal, 11–16 (–17) × (10–) 11–15 (–16) µm, laterally compressed (8.0–10.5 µm wide), yellowish brown; wall c. 0.8 µm thick, thinner on the flattened sides, finely and densely punctate to verruculose; spore profile smooth to rough.
