I have noticed lot's of Nettles covered in this rust at the moment.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
As usual I have to ask how this can be identified as var. urticata, unless its alternate sedge host is definitely known?
Identification best to just species.
Alan being awkward.
Thank's for your comment Alan I will in future if I put this type on again I will state species only.I don't think your being awkward as your an expert and I am amateur but I do try to take good photo's and write all the relevant details down when out looking and put quite a bit of effort into putting an identification on fungi I find I don't just pluck something that look's like it out of a book. I also use a microscope and take spore prints but my microscope is not capable of taking photograph's.
