?Eutypella on Alnus

The asci are pedicellate and 8-spored, IKI negative.
Spore measurements:
5.5 - 7.3 × 1.8 - 2.2 µm, Q = 2.6 - 4.2 ; Avg = 6.4 × 2.0 µm, Qav = 3.2 ; N = 10
I was thinking of Eutypella cerviculata, which I believe at least mostly grows on Alnus. However, these fruitbodies don't have the long necks as seen in many photos. Rather, they are just short stubs. Also, not sure about the yellow pigment.
Any idea what this is?

Re : ?Eutypella on Alnus
Yes, this sounds like a good suggestion. The inside of the fruitbodies looked greenish yellow in situ ("flavovirens"). Thank you!
