Veil (fungus)

Definition and stakes

Caroline A. Burgin,  Among the Mushrooms: A Guide For Beginners

“ The universal veil or volva is a thin covering which encloses the entire young plant. The cap grows and expands and bursts this veil into fragments. That part of the veil which breaks away from the cap, called the secondary veil, forms the annulus or ring. It resembles a collar, and is generally fastened to the stem. It is not always permanent or fixed in one place. It may disappear when the plant is mature. It is often fragile, loose and torn, and sometimes is movable on the stem. ”

“ It is only when the plants are fresh and moist that this condition of the veil can be seen, for on drying the veil collapses. Water is sometimes caught under the veil before the pileus separates far from the stem, and the spores falling thus float against the stem at this point and make a dark ring around the stem, which, however, should not be mistaken for the annulus. ”
