In mycology, a partial veil (also called an inner veil, to differentiate it from the "outer" veil, or velum) is a temporary structure of tissue found on the fruiting bodies of some basidiomycete fungi, typically agarics. Its role is to isolate and protect the developing spore-producing surface, represented by gills or tubes, found on the lower surface of the cap. A partial veil, in contrast to a universal veil, extends from the stem surface to the cap edge. The partial veil later disintegrates, once the fruiting body has matured and the spores are ready for dispersal. It might then give rise to a stem ring, or fragments attached to the stem or cap edge. In some mushrooms, both a partial veil and a universal veil may be present.

Famous quotes containing the words partial and/or veil:
“There is no luck in literary reputation. They who make up the final verdict upon every book are not the partial and noisy readers of the hour when it appears; but a court as of angels, a public not to be bribed, not to be entreated, and not to be overawed, decides upon every man’s title to fame. Only those books come down which deserve to last.”
—Ralph Waldo Emerson (1803–1882)
“In such a night, when passing clouds give place,
Or thinly veil the heaven’s mysterious face;
When in some river, overhung with green,
The waving moon and trembling leaves are seen;”
—Anne Finch, Countess Of Winchilsea (1661–1720)
