Diagnostic Notes
Sori filling the nuts with a black initially agglutinated, later granular-powdery mass of spore balls, inconspicuous, hidden by the somewhat spreading floral envelopes. Infection systemic; all capsules of a plant affected.

Spore balls subglobose, ellipsoidal, elongate to slightly irregular, 40–100 × 35–70 (–80) µm, yellowish to reddish brown or subopaque, composed of tens (30–100 or more?) of spores that separate readily by pressure.

Spores globose, subglobose, ovoid, ellipsoidal, elongate to subpolyhedrally irregular, 9.5–17.0 (–20) × 8–12 (–13) µm, olivaceous brown with slightly darker and paler areas; wall slightly uneven, 1–3 µm thick, thickest at the angles; in LM smooth, in SEM free surface very finely and densely low-verruculose.
