Melampsora pulcherrima is a Mediterranean plant pathogen. It is a rust that infects Mercurialis annua, causing galls, pycnia, and aecia over leaves and stem in winter, seen as a golden yellow swelling over several centimeters, as well as Populus alba, causing uredia and telia on leaves from spring until autumn.
