What is it???

Puccinia urticata

After some research & disbelief that I have never noticed it before. (My husband assures me that some nettles have had this every year) Maybe blip is making me look closer. :-)


Puccinia urticata is a rust fungus which develops on the stems and leaves of Common (Stinging) Nettle or Small (Annual) Nettle. It often starts as small orange blisters or swellings. Close examination may reveal the pinhead-like fruiting bodies of the fungus.
