fits Cystoderma granosum which fruits on wood. It is usually a larger mushroom but I still think this is what you have here. Cystodermella is not a synonym and it is usually terrestrial or on moss.
Whether Cystoderma granosum should be moved to another genus is another issue and I do not know.

Note that Cystoderma appears to be neuter and Cystodermella feminine so it’s Cystodermella granulosa (according to Index Fungorum).

Whether the ID is correct or not, the site has Cystodermella granulosum as a synonym of Cystoderma granosum. Index fungorum disagrees. Cystoderma granosum is distinct from Cystoderma granulosum…
