2.5. Diagnostic Notes **Sori** in stems, petioles, leaves and flowers, often extensive and causing distortion and swelling of the infected parts, filling the tissues with a blackish purple powdery spore mass.

**Spores** globose, subglobose or sometimes ovoid, 11–15 (–16) × 11–14 (–16) µm, violet-tinted light reddish brown; wall reticulate, 5–8 meshes per spore diameter; meshes 1–2 µm wide; muri 1.0–1.5 µm high, in median view appearing spiny; sometimes the walls of the meshes are incompletely formed and the common points of the meshes appear as warts; in SEM the reticulum irregular in shape and size, subpolygonal to sometimes round, interspaces with clavate or rounded sometimes confluent warts.

**Spore germination** resulting in a 4-celled basidium bearing numerous lateral basidiospores. 3. Diagnostic Images
