Diagnostic Notes
Sori on the leaves and leaf sheaths as small angular or short linear spots, 0.5–2.0 mm long, 0.5–1.0 mm wide, lead-coloured, usually not confluent.

Spores embedded in the host tissue, agglutinated but not forming spore balls, rarely subglobose, ellipsoidal or elongate, usually subpolyhedrally irregular, with 1 or several flattened sides, 6–11 × 5.5–8.0 µm, olivaceous brown; wall uniformly c. 0.5 µm thick, smooth.

Spore germination resulting in holobasidia on which several apically and passively released triradiate (Y-shaped) basidiospores are produced; basidiospores germinate by budding, giving rise to yeast colonies in culture.
