Protomyces pachydermus
The fungus Protomyces pachydermus causes galls on the leaves or flower-stalks of Dandelions (Taraxacum). The flower stalk or leaf midrib is swollen and twisted, initially yellowish then red or purplish. On leaves, purple-red swelling cause distortion of the leaf.
Some galls on midribs, stems and leaves may be caused by a fly larva.

Photograph the gall on the host plant. Ensure you have included a note of the host plant species in your comments. Opening the gall will help to rule out galls caused by gall-midges.
