I find this Split Gill mushroom in one of the tree stump in my working place. I might be wrong about the name of the fungi, but it is most likely. It might not developed yet, because there are alot of small fungi aroud the stump, because the develop one has a bigger size and usually stack on top of each other.
The tree is just recently being cut down as it damaging the building next to it, sad to see it being cut, but it is better than losing the building.
Thank you very much for your curation.
