Other Names Ustilago catenata F. Ludw. 2.5. Diagnostic Notes **Sori** in scattered flowers of a spike, at first compact and partially concealed within the utricle and covered by a fungal peridium, later exposed as the utricle splits longitudinally, elliptical, to 6 mm long. The well-formed but empty nut is pressed out by the sorus but remains attached to the utricle by its style. Peridium greyish white to brown, becoming shredded, exposing the dark brown dusty spore mass traversed by numerous conspicuous to 10 (–15) mm long fascicles of hyphae (elaters) composed of elongate hyaline cells. **Spores** rather regular, globose, subglobose, shortly elliptical to elongate, 6.0–9.5 (–10.5) × 5.5–8.0 (–9.0) µm, olivaceous brown; wall uniformly c. 0.8 µm thick, minutely and moderately densely verruculose. 3.
