Urocystis agropyri (Preuss) Fischer von Waldheim, 1867

Elongate narrow blisters between the nerves of the leaf. The brownish black spore balls that are released here consist of 1-2(4) spores, wrapped in a layer of smaller sterile, pale yellow cells.

host plants

Poaceae, narrowly monophagous

Agropyron cristatum; Elymus alaskanus subsp. scandicus, caninus; Elytrigia atherica, intermedia, juncea, repens; Leymus arenarius; Psathyrostachys juncea

Buhr adds Briza; this is not plausible; that also applies to a reference to Vulpia alopecuros by Almaraz.
