1. Parts of Fungus
1) Pileus
The pileus is the cap of the mushroom. A mushroom with a pileus is said to be pileate. A mushroom lacking a pileus, that is consisting of just a fertile surface with its back attached to or intergrown with the substrate, is said to be resupinate. Resupinate fungi usually grow on a substrate that is horizontal, like a fallen log.
2) Volva
A universal veil that hangs together like a skin is said to be membranous. The bottom half of a membranous universal veil is often left behind at the base of the mushroom`s stalk, forming a sort of a cup that the mushroom seems to be growing out of. This remaining universal veil tissue at the base of the stalk is called a volva, and the projecting part of the volva is called the limb. A volva possessing a limb is called limbate, and the edge of the limb is called the rim of the volva (it is sometimes called the margin, like the edge of the pileus, but I am only using the words in this mutually exclusive senses in this website). A deep volva that is shaped like a cup or sack is called a saccate volva.
