Urocystis pulsatillae-albae Vánky & Tóth, 2009
on Pulsatilla
gall
blister-like swellings on leaves, petioles and disfigured stems; when they rupture a black powdery mass of spore balls is released. The infestation resembles the one caused by U. pulsatillae, that may occur on the same host plant species, but the spore balls contain more spores, viz. 1-7(8), and are completely enveloped by sterile cells.
hostplants
Ranunculaceae, monophagous
Pulsatilla alpina.
