Unknown on Salix cinerea leaf
Johan Myhrer, 24-08-2018 19:21
On a very wet small old leaf under a Salix cinerera I found these apricot coloured apothecia, close to a river after rain. Central Sweden, 23 august 2018.

2-spored Asci: ~57x7µm

Spores: 14-15x5,5-6µm

Very interersting thing happened in IKI when two red dropplets appeared in spores.

I don't know where to start "digging" and will be happy for any suggestions. I know Rhytisma salicinum have a teleomorph state, could it be such fruitbodies? No traces of any previous states of that species on this leaf though.

Re : Unknown on Salix cinerea leaf
Ah, this is a Sclerotiniaceae, running under the name Hymenoscyphus kermesinus. On Salix but also Betula, typical for nordic countries.
I wonder why nobody sequenced this species to find out a proper genus name.

Re : Unknown on Salix cinerea leaf
Thank you for quick answer Zotto! Is there a description to be read somewhere?

There is a Peziza geminella Nyl. which is a synonym, see Dennis 1956 p. 182 fig. 161.

I have this species in my Moellerodiscus folder, but only with hesitation.
