Diagnostic Notes
Sori infecting all spikelets of an inflorescence, leaving the outermost floral envelopes intact, ovoid to cylindrical, 1–15 mm long, 0.5–1.5 mm wide (depending on the host species), at first covered by a pale brown peridium that ruptures from its apex exposing the dark brown semi-agglutinated to powdery mass of spore balls and spores surrounding a stout simple tapering columella.

Spore balls globose, ellipsoidal, elongate or irregular, 40–160 × 30–100 µm, dark brown to opaque, composed of tens to hundreds of readily separating spores.

Spores subglobose, subpolyhedrally irregular, mostly ellipsoidal, 8.0–10.5 × 6.0–9.5 µm, yellowish brown; wall uniformly c. 0.8 µm thick, finely punctate to verruculose; spore profile smooth, in SEM finely verrucose-echinulate, the spores often appearing mamillate.

Sterile cells not seen.
