The following smut fungi reported from Hyparrhenia hirta were studied: Sporisorium andropogonis, S.bardnonense, S. puellare , and S. transfissum . Two new combinations are proposed: Sporisorium barcinonense (Riofrio) Vanky, and S. puellare (H. Sydow) G. Deml. S. andropogonis and S. puellare have morphologically identical spores but differ in the type of spore germination. While S. puellare germinates by a ramified mycelium, S. andropogonis produces four‐celled basidia forming basidiospores laterally and apically. It appears that S. andropogonis is restricted to Dichanthium ischaemum , and S. puellare to Hyparrhenia hirta. S. harcinonense and S. transfissum , both producing the same type of floral infection, are differentiated by their spore measurements.
