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:
“And meanwhile we have gone on living,
Living and partly living,
Picking together the pieces,
Gathering faggots at nightfall,
Building a partial shelter,
For sleeping and eating and drinking and laughter.”
—T.S. (Thomas Stearns)
“For me, it is as though at every moment the actual world had completely lost its actuality. As though there was nothing there; as though there were no foundations for anything or as though it escaped us. Only one thing, however, is vividly present: the constant tearing of the veil of appearances; the constant destruction of everything in construction. Nothing holds together, everything falls apart.”
—Eugène Ionesco (b. 1912)
