Diagnostic Notes
Sori surrounding the pedicels and main axes of the inflorescence, only rarely in the flowers, fusiform, ellipsoidal or globose, 5–40 (–70) mm long, 3–10 (–20) mm wide, black, composed of compact spore masses with a powdery surface traversed by fascicles of sterile hyphae that extend beyond the spore masses.

Spores in irregular groups, becoming solitary, globose, subglobose, ellipsoidal, irregular or pyriform, 13–19 × (11–) 12–17 µm, olivaceous brown, with a 2–3 µm thick wall, forming the basal part of the sori in radially arranged sporogenous hyphae. Immature spores catenate, fusiform, yellow, thick-walled, smooth, becoming larger, ellipsoidal or globose, pigmented, with a cracked exospore.

Spore germination of freshly collected spores (in water, at room temperature, after 5 days) resulting in septate basidia or long filaments. Basidia giving rise to hyphae or to shorter or longer fusiform basidiospores that separate readily.
