Hymenoscyphus

Hello others
This Hymenoscyphus I found in a beech forest on limestone. She grew up on a branch of a beech tree. The hymenium is colored yellow. The spores are comma-shaped and measure 19.5 to 21.2 x5 0.2 to 6. Could this be Hymenoscyphus serotinus? Irritated me only the color slightly. Can it be that the black fruiting bodies?
regards
Eike?

Re : Hymenoscyphus
H. serotinus is restricted to Fagus.

Re : Hymenoscyphus
Have you more photos of spores? The spore width is impossible for H. serotinus (better is 3-4 µm), but your photo suggests that they are narrower than 5-6.

Re : Hymenoscyphus
Hallo Zotto

das Sporenbild ist bei 400x gemacht. Vlt wirken deshalb die Sporen schmaler

Re : Hymenoscyphus
Ja, Buche ist obligat. Leider bin ich immer noch nicht sicher. Es ist unbedingt wichtig, Sporen bei Ölimmersion zu fotografieren, obwohl bei solch großen Sporen auch Übersichtsfotos brauchbar sind, aber die Sporen sollten gut auf der Seite liegen.
