Margaux's observation - Poronidulus conchifer
The poronidulus conchifer, also called trametes conchifer, is a type of fungus. I made an observation of them on dead tree branches. This organism looks like "a cup fungus or a bird's nest fungus without its eggs" often white or yellowish. To add on, their cup-like form helps them in asexual spores dispersal, which is their method of reproduction.
