Black apothecia with yellow "matter" on Sorbus

Hi,

These small apothecia were growing on dead Sorbus wood. Hymenium greyish. Excipulum partly covered with yellow "matter" which dissolves and turns purple in KOH (but apothecia without the yellow matter do not show a ionomidotic reaction). Excipulum cells greenish in KOH, consisting of bulbous/clavate, hair-like cells. Spores 9-10 x 2-2.5 my, ellipsoid, possibly becoming 1-septate, with a few guttules (?) - very few mature spores seen. Asci IKI-.

Any suggestion?

Thanks and regards.

Hi Edvin

Perhaps two diferent fungis? The yellow one parasiting an old pyreno?

No old pyreno here. There are only black apothecia. But I will will check what appears to be remnants of a subiculum.  Thanks.
