What are these spots on the leaves of Sanguisorba officinalis?
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.

I think that you are right. Presumably the orange will appear beneath the leaves in due course. Would you care to add the ID as a suggestion?

Indeed I am! Thanks.
For anyone reading this, the link is to a checklist of British rust fungi and their hosts.
I did look at Phacellium but erroneously decided on a Rust.
Alan, thanks for the (speculative) ID. Since this has not been confirmed in Britain before, would you be interested in looking at a specimen? I might be able to arrange this.
All we see are leaf spots, I don't think the minute tufts of the fungus are there. It is common experience to find leaf-spots that cannot be confirmed further. Even with presumed Ramularia rubella on dock leaves, in which the fungus itself is commonly visible, I often have to examine several leaves before I find it, and more often discard spotted leaves as unidentifiable.
Possibly these Sanguisorba leaves may produce something when older, but I wouldn't bet on it.
I have more than enough of my own stuff to look at than I can manage, so no, I am afraid I have no great enthusiasm for this.
OK. That's fine. Thanks.
