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.
