Hymenocyphus or Rutstroemia
Pavel Jiracek, 08-10-2024 13:44
I think this is R.bolaris. How can I verify that and eliminate Hymenocyphus?

On a piece of unidentified wood (Alnus, Crataegus?), Central Scotland.

Spores 16x5, asci 130-140x10-11
Fruit bodies up to 8 mm across.

Thanks

Re : Hymenocyphus or Rutstroemia
Clearly a Hymenoscyphus, and it looks much like the common H. subferrugineus.

Re : Hymenocyphus or Rutstroemia
Thanks, Hans-Otto,
Can you, please, share what made you identify it? Macro micro or both?
It is large, 8mm.

Re : Hymenocyphus or Rutstroemia
You can look into my folders, I have a folder "Hymenoscyphus calyculus-group".

In a wide sense this is H. calyculus, but I learned by type studies that H. subferrugineus (= Helotium broomei) fits what I often found, whereas H. calyculus remained a very difficult species which I did not see since again a long time.

H. subferrugineus has a bit shorter, more cylidrical (less scutuloid) spores.

My article on this is regrettable still unfinished.
