Common Psathyrella Mushrooms

Hello Fungi Lovers! Glad to be back here again with some pictures of the little wild mushroom that I found in the rotten banana tree. I bet this is a type of edible mushroom but I still doubt about consuming it. I found this one when I was walking in the wood, due to small size I barely noticed them growing under the wet rotten tree but by the time I had a clear vision that there were some little mushrooms hiding there, I grabbed my camera and started to play with the clicks. If I am not mistaken, this typical mushroom is called common psathyrella that grow in grassy areas,
developing from buried wood or from roots.
