Genus Ossicaulis

How do I name this very interesting mushroom, I am very interested in this mushroom because this mushroom has a very elegant color, which is white, and not only the color that makes me very interested, because the shape is also similar to an elephant's ear, so this mushroom can be seen from a fairly far distance. the size of this mushroom is also not too big but also not too small, and I can say that the size of this mushroom is still relatively normal like other mushrooms

I found this mushroom right under a guava tree and this mushroom grows well on dead guava branches, coincidentally the location of this mushroom grows right next to the gutter, so of course this drying has a cold and of course humid environment. According to some people this mushroom can be eaten and many also say that this mushroom cannot be eaten aka poisonous, I didn't really mind because at that time I was only interested in seeing it.
