Gelatinous hyaline discs (Exidia ?)

The bodies were jelly-like and very difficult to slice, hyaline or slightly pulverous above, astipitate, cushion-like bodies sitting on the surface of a decaying twig, sometimes coalescing to form colonies. Some individuals had a pale ochraceous granule at the centre which under the microscope seems to be abiotic and disintegrate into amorphous particles
When finally I sliced a section, I could see a meshwork of numerous 'hyphae' without any special reproductive organs. No spores could be detected.
Is it an Exidia?
Sliced section shows a central amorphous body suspended in a loose gelatinous tissue composed of loose hyphae in a meshwork network (very thin - 1um ) and an outer layer made up of a different denser tissue, but without any special organs (eg asci)

Re : Gelatinous hyaline discs (Exidia ?)
Hello Stephen,
although the micros are very small, I am quite sure that your fungus is not an ascomycete but a Heterobasidiomycete.
Best regards, Lothar

Re : Gelatinous hyaline discs (Exidia ?)
Dear friends,
I agree perfectly - I just examined better the slide and although I could not see the spectacular basidia of this genus, there are 'basidioles' which are matching with those of Exidia sp. The central calcium oxalate deposit is typical of Exidia nucleata:

I washed the specimen in KOH and maybe I washed away the spores from the surface. I'll prepare a slide from a raw specimen. COOL!
