Identifying fungi in oil palm plantations part II

On December 4th, at precisely 4 pm, one of my friends and I went back to look for coconut leaves in the oil palm plantation area. In this hunt, we got the results we wanted. here I found a mushroom stem Candolleomyces candolleanus which grows in a bush, this mushroom is one of the mushrooms in the family Psathyrellaceae this mushroom usually grows only a few stems, not including mushrooms that grow in groups, color The mushroom varies between dark white and light brown, the surface of the umbrella of this mushroom has two different colors, white and brown in the middle of the surface, at a young age this mushroom is cone-shaped and then becomes evenly rounded, the size of this mushroom is quite large, which I found today The umbrella is around 3.5-4.5cm with a stem height of around 10cm. What is interesting about this mushroom is the membrane that holds the umbrella together when it is young so that the umbrella doesn't open. At this old age I can still see the membrane holding the umbrella of this mushroom so it doesn't open. , even though this mushroom's umbrella is already maximally open, this is what is called unique in the wild.
