another Hymenoscyphus type ... ?

I have found several of these small ascos recently growing on soft, dead stems of (possibly) Rubus fruticosa. The limited keys I have find nothing with such long spores!

could anyone suggest what this one could be.

Merci d'avance, Alan

Re : another Hymenoscyphus type ... ?
Clearly a Hymenoscyphus with scutuloid spores, but you need more data. I assume the asci arise from simple septa and the paraphyses contain refractive VBs.  Probably H. scutula (incl. vitellinus) in a wide sense, perhaps H. virgultorum. But 7 µm spore width would be impossible. You shoud measure more spores I think you have narrower but also longer ones.
