The rust fungus Puccinia hieracii var. piloselloidearum affects only Mouse-ear-hawkweed (Pilosella) species. It can cause severely affected plants to become weaker and is a gall-causer.
Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed. If at all possible, ask an expert to examine the affected material.
Wherever Mouse-ear-hawkweed (Pilosella) species occur.
The rust may be seen whenever Mouse-ear-hawkweed (Pilosella) species are in leaf.
It seems to be widespread in Britain, but lack of records makes it difficult to determine the exact status.
