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 proliferation of the inflorescence and also transvestism (infected male plants transformed into female ones with sori).

Spore balls subglobose, ellipsoidal to irregular, 25–60 × 20–50 µm, dark olivaceous brown, composed of 4–40 (or more) readily separating spores.

Spores subglobose, ovoid, ellipsoidal to subpolyhedrally irregular, 11–16 (–17) × 9–13 µm, olivaceous brown; wall uniformly 1–2 µm thick, apparently smooth to finely and densely punctate; in SEM finely and densely verruculose-echinulate.
