Ustilago constantineanui (Săvulescu) Vánky, 1985
Fungi, Basidiomycota, Ustilaginomycetes, Ustilaginales
scattered ovaries are modified into a somewhat pulverulent dark olive brown mass of spores; initially the sorus still is covered by a greyish to brownish membrane consisting of both fungal and plant material. The infection is inconspicuous because the sori remain hidden by the glumes. Spores mostly 8-10 x 9-13 µm, moderately to coarsely verrucose.
Crypsis aculeata, alopecuroides, schoenoides.
