Hello! Puccinia lycoctoni or Uromyces lycoctoni?
Substratum: leaves of Aconitum lycoctonum ssp. ranunculifolium
Thanks!
[img][/img] As far as I can see, your micro image is of aeciospores. According to one of my literature resources, Puccinia lycoctoni only forms teliospores, so that would make your find Uromyces lycoctoni. According to another, Puccinia lycoctoni does produce aeciospores, similar to those reported for Uromyces lycoctoni. My guess is that the first of these is correct, but to be sure you will have to wait for the teliospores to form later in the year. Life is never simple, but you may be able to add to our knowledge of the group… It would help us all if you can provide measurements for the micro images in future, and also give us an idea regarding where the collection was made. Is it British?
Best wishes
Paul
