A minute non-Mycena brownish basidiomycete!

Good Morning. From my archives of unidentified fungi, here I am showing a tiny fungus, barely 4 mm tall and 2mm wide growing on decaying bark of Ceratonia siliqua (carob). Micro is not available since I have neglected this collection to spend time on others. It can be an abnormally small fungus of some common species, like a Psathyrella sp. (melanthina?) or whether it is the normal size of a fungus that I don't know at all !!! In desperation, I tried googling 'tiny brown mushroom' but I got a bunch of Panaeolina, Conocybe and Mycena and unrelated searches. == twitch
