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?

Re : Discomycet on Salix.
Yes, it was growing on an attached, decorticated branch, above ground. Per

Re : Discomycet on Salix.
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:
