Melanopsichium austro-americanum (Spegazzini) Beck, 1894
on Polygonum
gall
resembling M. pennsylvanicum, but the spores are more or less smooth rather than echinulate.
hostplants
Polygonaceae, monophagous
Polygonum aviculare.
notes
despite the fact that Vánky wrote that all European material seen by him actually belonged to pennsylvanicun, austro-americanum is listed by Almareez, on the bases of a single record, in her survey of the Spanish Ustilaginales.
