Black apothecia with greenish septate spores on Picea abies twig

These black, erumpent, initially closed apothecia were found in small groups on a thin twig of an old spruce tree in February, in a mountainous area in central-southern Norway. They eventually open and disclose a yellowish white hymenium. The spores are greenish, which can be seen even in reflected light. The largest, open apothecium measure 2 mm.Asci are 4-spored, clavate with a very long, alomost hypha-like base, ca. 20 micr. across at their broadest. Paraphyses filiform, ca. 1 micr. thick.
Spores 3-septate, greenish at maturity, 25-30 x 9-10 micr.
Asci stain blue in Lugol, somewhat stronger towards the apex. Asci also weakly blue in Lugol after pre-treatment with KOH and water rinsing. Spores possibly also somewhat amyloid, but masked by the initial green color of spore wall.
Are we in Ostropales? In the "vicinity" of Tryblidiopsis? Opinions appreciated. Thanks!
