Sori on the leaves, leaf sheaths, stems, floral axes and rachis, initially as yellowish green later lead-coloured non-erumpent spots, linear on the leaves or by coalescence fusiform or irregular sometimes covering nearly the whole leaf blade, 1–20 (–30) mm long, 0.3–5.0 mm wide, up to 80 mm long on the stems.

Spores embedded in the host tissues, crowded, often in irregular groups or rows; individual spores ovoid, ellipsoidal, usually irregularly subpolyhedral, 8–14 (–16) × (6.5–) 7–12 µm, dark reddish brown; wall uneven, smooth, 1–3 µm thick, thickest at the angles.

Spore germination resulting in holobasidia on which apically passively released basidiospores are produced.
