These were growing on a dead Rubus idaeus cane at the turn of June and July 2020.Â
There were just a few pics of the spores, asci in IKI and excipululm. The spores measure 7.9 - 10.4 × 2.1 - 2.6 µm.
Is this enough to determine this as P. rubi or are there other alternatives?

Re : Pyrenopeziza rubi?
P. rubi or P. escharodes - i cannot say. Both are described with marginal, appressed hairs.
There is an interesting iodine reaction when pretreated with KOH and wahsed with water: Lugol and probably also Melzer give a distinct blue at the margin! I am not sure if this distinguishes rubi from escharodes.

Re : Pyrenopeziza rubi?
Ok, thanks for the info! I'll have to keep that in mind until I find this again.
