Diagnostic Notes
Sori in the nuts, ovoid with an acute tip, c. 1 mm long and 0.5 mm wide, replacing the seeds with a black granular-powdery mass of spore balls. The fungus induces transvestism in the host.

Spore balls globose, subglobose to ellipsoidal or slightly irregular, 30–70 × 20–50 µm, dark olivaceous brown, composed of 10–30 (or more?) readily separating spores.

Spores subglobose, ellipsoidal or somewhat irregular, with 1 or 2 slightly flattened sides, 11–16 × 8–13 µm, yellowish to olivaceous brown; wall uniformly 0.5–0.8 µm thick, smooth; free surface very finely verruculose.
