Re : Hyalacrotes
Salut Elisabeth!
C'est Hyalacrotes hamulata oui? Sensu Raitviir...
I am just back from a trip to Swedish fjälls and found this very same thing there, rather plentiful on old Aconitum stems. Following Raitviir we could only come up with Hyalacrotes hamulata. Looking at Zottos folders, the "hamulata" there (under Unguiculella) is lacking the yellow pigment that is clearly present in your collection. Otherwise they all fit pretty ok together.
First time ever for me, a very beautiful fungus indeed! It was a very lush Aconitum growth with some Filipendula ulmaria and Epilobium angustifolium. Yes!

Re : Hyalacrotes
Hoi Elisabeth & Timo
take care with Unguiculella hamulata: This is a Feltgen species and lacks any glass, also the spores are much smaller and the asci inamyloid.
What you mean is Hyalacrotes hamulata (Rehm) = Urceolella hamulata. That species I have, oddly enough, in my Iridinea folder in Naevioideae! And yes, in the specimen that I studied the disc was cream-ochre due to a pale yellow-orange hymenium in section and a pale ochre subhymenium.
The spores only get septate when overmature, inside living asci they should be non-septate.
I am very curious what the molecular data will hopefully tell us!

Re : Hyalacrotes
Ah, right, I was a bit too fast. Thanks Zotto, that explains.
-I will certainly dig out DNA from this one...

Re : Hyalacrotes
Hello Timo & Zotto
Many thanks, (in my case only on old Epilobium stems) now i understand, spores are septate because overmature!
