Ascolichen or lichenicolous fungus?

Dear all.Ascomata pheritecioid, KOH-negative, flask-shaped, black, melanized, ostiolate and up to 0.5 mm high, semi-inmersed o a thick layer of green algae over old thalli of a Frullania species on hardwood. The hymenium is hemiamyloid, reddish in IKI, deep blue after KOH-pret. Periphyses numerous, pseudoparaphyses or paraphyses not seen. I think the asci are not bitunicate, but I can't say for sure. The ascospores are hyaline, very pale yellowish brown at maturity, (3-)6-7 transversaly septate and smooth.
I really can't tell whether it is an ascolichen or a lichenicolous ascomycete. Would any of you have any ideas that could help me?

Re : Ascolichen or lichenicolous fungus?
This is a lichen, not a lichenicolous fungus. It strongly resembles species of Agonimia, but in that genus, ascospores are always (sub-)muriform.

Re : Ascolichen or lichenicolous fungus?
Hallo, I agree that it is a lichen. In my opinion it could be a richly fertile specimen of Normandina chlorococca (Leighton) Orange, recently segregated from N. acroglypta by the late Alan Orange in Lichenologist 54 (2022). Both N. acroglypta and N. chlorococca are often associated with Frullania liverworts, and both species may even grow together on 'mossy' ultramafic (serpentinic) rocks. The epiphytic/epixylic stuff usually refers to N. chlorococca, which is normally sorediate sterile crust and only rarely fertile. The two species are reliably separated by chemistry, different terpenoids.

Re : Ascolichen or lichenicolous fungus?
Thank you Paul and Zdenek.
It matches perfectly with Normandina chlorococca!

Hi friends,
Zdenek, I would be interested by Orange's paper because I met N. acroglypta in my fields.
Best wishes,
