Hi Eduard,

looks a bit like Coenogonium/Dimerella pineti (a lichenized ascomycete) to me...

Best wishes,
Gernot

Hi Gernot

Thank you for your prompt reaction! I think you are wright, if I compare it with pictures available on Internet e.g. http://www.freenatureimages.eu/Plants/Funghi,%20Paddestoelen,%20Mushrooms%20and%20Toadstools/Dimerella%20pineti/index.html.     The paraphyses are very much the same.

I hadn't considered the possiblity of a lichenized ascomycete, which can be explained by the inconspicuous thallus: "Thallus very thin, effuse, scurfy, green-grey to greenish black but may ± disappear apparently to leave only the apothecia; apothecia fleshy, short-lived (winter-spring), to 0.5mm in diameter, translucent-pallid to pinkish or sometimes pale orange, sometimes accompanied by white pycnidia. Widespread but minute and easily overlooked, on shaded bark, sometimes on other substrates, including soil."

Thanks a lot for the identification!
All the best, Eduard

Hi Eduard, 
the hymenium with that granulous, orange pigment does not remind Coenogonium to me.
