Found a number of these structures on Nettle Leaves in the wood, assuming they are galls


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Thanks Murdo

Its easier down here to find things , but just as difficult as at home to ID!

That is a very helpful

That is a very helpful comment, Alan. I have been trying to get clarity on this for some time. Until last year, I have always called it P. urticata, but stopped when the NBN/R6 dictionary seemed to say otherwise (look at the NBNG map for P. urticata, http://data.nbn.org.uk/gridMap/gridMap.jsp?allDs=1&srchSpKey=NHMSYS00014...).

Just last week I asked our local rust expert for clarity, but have not had a reply. My intention was to flag my concerns about the dictionary with the NBN forum, which I will do now, as I am now certain in the light of your comments that the synonymy and links to preferred names are not as they should be.

I follow the BMS/CABI GB checklist of fungi, which is as up to date as anything.

However, the NBN seems to be trying to map the individual varieties, which is fine if one has it on a sedge host, but I don't know to what extent they can be separated when on nettles. It does seem that a lot of records for the species have disappeared somewhere.
