Pyrenopeziza on Alnus viridis

Dear Friends,This little discomycete appears every year on overwintered leaves of Alnus viridis near my home in New Brunswick. It looks a lot like the fungus Roland recently reported on Physocarpus opulifolius? except that it lacks verruculose hairs. It is similar in appearance to Pyrenopeziza fuckelii but the spores are too large. Any suggestions?

Re : Pyrenopeziza on Alnus viridis
Dear Dave
my idea is that this is Pyrenopeziza betulina (Alb. & Schwein.) Rauschert? = Pyrenopeziza betulicola Fuckel.
This species has a complicated history, and it was even placed in Orbilia.
It is close to P. fuckelii = Microscypha monticola on Salix, but differs in longer spores. Ingo Wagner observed this difference in spore size also and made nice photos. I was so far only aware of finds on Betula, but it is no surprize to me that it also grows on Alnus.

Re : Pyrenopeziza on Alnus viridis
Dear Zotto,
Thank you for your informative and very prompt reply.
This fungus is VERY common here every spring and I am very pleased to have a name for it. Nothing is more annoying than being unable to identify a common fungus. I will check to see if this fungus is also on birch leaves.
Dave
