Three Ascomycetes

I found some Ascomycetes which I am not able to determine. The first Ascomycet (the black balls, not the thin hairs) grew on bark of Sambucus and has hyaline, warted spores with 11-12,5 x 6,5-7 µm.
The second one, I think a Diatrypaceae, grew on the inner side of bark of a living Acer pseudoplatanus and has spores with 8,5-12 x 2 µm.
The third one reminds me of a Nectria but I did not see any asci, only spores with long stipes as if they would germinate. Spores: 13-14 x 6-7 µm.
I would be very thankful if you could help me!
Best wishes,
Gernot
