Re : Discomycet on Salix.
Are these micropics in Melzer? Did you test to mount in water and separately KOH?
Would be interesting to know if the apos are ionomidotic (KOH releases a brown pigment in the medium when added to a water mount).

Are the asci still inamyloid when KOH-pretreated?

One idea is Austrocenangium nanum, which gets a greenish hymenium in KOH. But that is a South American genus. Where is your sample from?

Re : Discomycet on Salix.
Hello.
It was found in the south of Norway in the autumn 2015.
I use KOH on my dried fungi.
Melzer for amyloid-test.
Ionomidotic-test is new for me.
If it is of interest I can send it to you.
Greetings, Per.

I will wait for Kadri Pärtel's (Estonia) opinion, maybe she is interested to receive it.

Re : Discomycet on Salix.
On Salix means that it grew on an attached branch above ground? Decorticated?

Yes, it was growing on an attached, decorticated branch, above ground. Per

Kadri wrote she would like to study this. I think she will need about 4-5 apothecia if it is rich enough.

Here is her address:
