I recently found a collection of small Peziza sp.
Here's already my next problem:
Substrate: (Yet) Unidentified deciduous wood
Macro: Apothecia, up to 0.5 mm diam. (as single apothecia), exceeding 1 mm in confluent parts. Densely aggregated and often more or less coalescing to confluent parts. Black, with a distinct margin when young, then flat without margin and later convex. Exuding as a red-brown colour in KOH.
Micro: The whole disc is incrusted with a brown substance and structures are difficult to see when prepared in water. This Substance dissolves in KOH as a reddish exsudate and then the structures are hyaline to distinctly green. Asci 35-40 x 5 µm, IKI-, Melzer-, Spores hyaline, 4.5-5.5 x 1.2-1.6 µm, with two oildrops, aseptate. Paraphyses about 1 µm diameter. Excipulum not clearly differentiated from medulla, the medulla consisting of gelatinous tissue with loosely intertwined, irregularly expanded hyphae (Photos).
Thank you for any help

Ist was Durelloides.
danke, das hilft! Vergleiche mal meine Zeichnungen im Verzeichnis Phaeangella = Durella redbrown, und da "bigutt spores narrow ionom". Da sind zwei Funde, einer aus USA, der andere aus Luxemburg. Die wuchsen aber an ansitzenden Ästen.
Hast du keine Skala in deinen Fotos? Dann könnte ich etwas nachmessen.
Das Auflösen und Austreten des rotbraunen Pigments ist typisch für diese Art (ionomidotisch). Irgendwie erinnert er auch an Ionomitodis fulvotingens, aber nur mikroskopisch inklusive Excipulum.

Asci tot 45 x 4.5-5.5 µm,
Sporen etwa 4,5-5,5 x 1,8-2 µm
