Dear Forum membersI received this find from a friend. Could this be a species of Gorgoniceps?
On soaked hardwood (decidious forest)
Apothecia 05-0.5x0.3-0.5 mm, light greyish green; without hairs, the' hairs' on the macro picture may be some emerging asci.
Spores: 40-45x4-4.5 µm with 7, quite thick, septa, hyaline with refractive content
Asci 110-120(140)x 11-13(17) µm,with croziers, IKI+, top and wall blueing
Paraphyses: 100-120x2-2.5 µm; filiform, with refractive content
Textura porrecta, textura poorly developed
Thanks in advance for any reaction.
Regards, Lieve
I think it could be a Strossmayeria.

Dear Gernot
I looked at it again and read the introduction of Iturriagas & Korfs 'Monograph of the discomycete genus Strossmayeria, with comments on its anamorph'. Because of the amyloid spores I was wrong. Asci IKI-, spores IKI+.
Thanks for your advice and also thanks at Hans-Otto!
on your photo the asci are inamyloid. I know about the amyloidity of spores, but I am not sure if I ever saw it. On the other hand, the blue excipular reaction is wquite distinct.
Maybe the spore amyloidity is only visible in overmature spores, as in Durella connivens which is phylogenetically closely related.

Here in attach an arrangement of pics by Ingo Wagner which shows the reaction in Durella connivens quite well.
