short description:
tiny (!), orange, discoid apothecia with slightly raised margin with a pale initial covering (?). Spores 10.4-10.9 x 7-7.3 µm, apparently smooth, thick-walled;in 8-spored asci with apical thickening (operkulum presumably). Text. rather dense. Asci ca. 90 x 12 µm, mostly with spores uniseriately arranged but with a tendency to being biseriate in the middle.

Are you sure this is an operculate discomycete?
Maybe a picture of ascus base would help. Is it possible to have some pictures without phase contrast?

My microscope is not well equipped for standard BF so I probably cannot come up with better images. I have no other suggestion than it being an operculate but I have not seen a pushed aside operculum. The substrate, the colour and the absence of a stipe and I guess spore shape points in the direction of the operculates. I think I can observe croziers on some of the images
