Puccinia aconiti-rubri

belongs in the recondita-complex and has a host change with Festuca rubra (hence the name). In this species the aecidia do not emerge from discoloured patches on the leave.

What about

Puccinia aconiti-rubri? Is this a synonym to one of the mentioned species? I recently found some Puccinia on Aconitum lycoctonum myself and named it thus.

Puccinia species

This is a Puccinia species, but on Aconitum there are several species.
First there is Puccinia recondita, which parasites all Aconitum species incl. A. lycoctonum. P. recondita is an aggregat which is hardly seperable without knowing the changing host (in all cases a grass). If you have only the aecidia, the different species in the recondita complex can be separated by their occurence within small discoloured areas, big discoloured areas or no discoloured areas at all.
Second there is Puccinia lycoctoni. This species grows exclusively on Aconitum lycoctonum and has no changing host, so you find the telia on the same substrate as the aecidia, and (important!) on both sides of the leaves.
An lastly there is Uromyces lycoctoni, which als grows exclusively on A. lycoctonum and also has noch changing host. Here the telia are grwoing only on the underside of the leaves.

The aecidia offer nevertheless some characteristics, but I don’t dare to judge which of the two Puccinia is your species.
In P. recondita the aecidia a cylindrical to long cup-shaped, the margin being dissected and turned backwards
In P. lycoctoni they are cup-shaped, the margin being white and crenulate
In U. lycoctoni they are flat dish- to disc-shaped, the margin being very obsolete and soon beginning to fall apart.

I nevertheless tend to Puccinia lycoctoni, because the margin don’t seems to be bent backwards and moreover it is not 100% sure whether P. recondita occurs on Aconitum lycoctoni or not.

Have a look

at Puccinia recondita, at least Aconitum is mentioned as one of the hosts.
