Diagnostic Notes
Sori in all nuts of an inflorescence, elongate, protruding beyond the floral envelopes, cylindrical, slightly bent, 3–6 mm long, 0.5–0.8 mm wide, with acute tips, filled with a black granular-powdery mass of spore balls. The fungus induces transvestism in the host.

Spore balls globose, ovoid, elongate or irregular, 40–130 (–140) × 40–80 µm, yellowish to reddish or dark olivaceous brown, permanent, composed of tens to 100 spores that separate into groups by strong pressure.

Spores subpolyhedrally or polyhedrally irregular, with 1 or several flattened sides, 9–16 (–19) × 8–11 (–12.5) µm, pale olivaceous brown; wall uneven, 1–3 (–4) µm thick, thickest at the angles, often with short acute tips at the angles and narrow lines on the surface; contact sides smooth; free surface with low irregular warts and remnants of the sporogenous hyphae.
