Any help for determination will be appreciated.
Boubovia ovalispora?
Thanks for your proposal and maybe/probably you are right but on "https://svampe.databasen.org/observations/10208492" the spores of B. ovalispora are ellipsoid, smooth, multiguttulate and measure 12,6-13,2 x 7,6-8,4 µm, which is shorter than 14-16,6(-18) x 7,5-10,5 µm in my found. That makes me a bit doubtful.
I would be grateful to recieve a key of the genus Boubovia.

I remember that you lately posted Pictures of Pseudopithyella minuscula.
In our area (Center west of France) it is often collected with Pesudoboubobia benkertii. Some features of your collection would match but for the substrate . P. benkertii lies on woodchips or dead leaves of Cupressus macrocarpa.

Thank you very much for the identification. In my garden it was also found nearby Pseudopithyella minuscula.
Kind regards and happy new year.
