Its scientific name references its tendency to position itself in the higher points of any individual tree. The fruit bodies may grow alone or in small clusters of two or three, and rarely more.

General Info
Edibility
Elm oysters are edible, although they are unrelated to the more commonly sought-after "oyster mushrooms" of genus Pleurotus. Though sometimes hunted in the wild, they are also a very popular species for home cultivation. They boast a delicious flavor, although their texture can be a bit tough (especially towards the base of the stalk, which is often cut off). Elm oysters should always be cooked before they're eaten, and they can be used in a wide variety of soups, stews, and pasta dishes.
