McAlpine, describing material collected near 
Brisbane by Bancroft in 1879, remarks that the 
galls are formed in the stem in the Queensland 
specimens; in North America they are chiefly in 
the inflorescence, and in South America chiefly 
on the leaves. The fungus is common on the 
various species of Polygonum of the water pepper 
type by the creeks and rivers round Brisbane, 
and galls are commonly found in inflorescences, 
more rarely on leaves.
