I have found this big Hymenoscyphus ealier two times, but only one fruitbody a time.
Then it grew on Ribes and propably on Salix.
These were even 5 mm wide.
The spores are about 15-20x4-5 and asci 90-130x8-9. Paraphyses may be a bit longer than asci.

Re : Hymenoscyphus on Prunus padus
Dear Zotto,
I noticed, that one of H. calyculus synonyms is H. virgultorum.
I have found it many times and it has been yellow.
So it was no option for me in this case.
Some times I have noticed yellow and white Hymenoscyphuses on the same stem of a herb, but now this is a tree and the colours are quite different. How much can the colours of the same species vary (I know, that the size of Hymenoscyphuses can vary much depending of the substrate)? Is it a matter of the substrate (metabolism) or lack of light (because this and also the others were shadowed)?
Sorry Zotto, things like this raises questions in my mind and makes me curious...

Re : Hymenoscyphus on Prunus padus
Colour can actually vary, yes, and one reason may be light. But H. virgultorum I use for a species with very different spores, here attached. Spore asute, especially at the base, filled with small doplets. If anybody can argue against this interpretation I would be very interested.
