Diagnostic Notes
Sori in scattered hypertrophied ovaries, long-cylindrical, often slightly bent, 10–25 mm long, 1.0–1.5 mm wide, covered by a hispid membrane of host origin with parallel veins. At maturity, the membrane ruptures longitudinally exposing the dark brown powdery mass of spores and sterile cells.

Spores subglobose, ovoid, ellipsoidal to elongate, rarely irregular, 16–23 × 16–21 µm; elongate spores to 26–30 µm long, yellow to yellowish brown; wall uniformly 1.5–2.0 µm thick, including the irregularly scattered 1.0–1.5 µm high warts.

Sterile cells subglobose, ellipsoidal to slightly irregular, often collapsed, 14–25 × 13–23 µm, pale yellow; wall 0.5–1.5 µm thick, smooth to rough.
