Diagnostic Notes
Sori in all nuts of an infected plant, c. 3 mm long and 1 mm wide, hidden by the floral envelopes, filled with a black granular-powdery mass of spore balls.

Spore balls globose, ovoid, ellipsoidal, elongate or irregular, 40–80 (–90) × 30–60 (–70) µm, yellowish brown, permanent, composed of tens of spores that separate by strong pressure.

Spores usually subpolyhedrally or polyhedrally irregular, sometimes rounded or elongate, commonly with subacute or acute tips at the angles and also with narrow lines between two flattened sides, 10.5–16.0 (–18.5) × 7–11 (–12) µm, pale olivaceous brown; wall 0.5–1.0 µm thick, smooth on the contact sides, rough and finely verruculose on the free surfaces.
