Clearly visible webby partial veil (cortina), hiding the stalk. A veil or velum, in mycology, is one of several structures in fungi, especially the thin membrane that covers the cap and stalk of an immature mushroom. [1] Veils fall into two categories: Partial veil; Universal veil
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 ...
The fungus has long been recognised to have antibacterial properties: the addition of the fungus to soup broth was known to prevent it from spoiling for several days. [69] One of the responsible antibiotics, albaflavenone, was isolated in 2011. It is a sesquiterpenoid that was already known from the soil bacterium Streptomyces albidoflavus. [69]
An organism that lives within a plant; in mycology, specifically fungi that live within plants but do not show external signs or damage to the plants. This is usually endomycorrhizial fungi in root systems and asymptomatic fungi in aerial plant parts [108] endospore 1. An endogenous spore, e.g. a sporgangiospore, often resembling an ascospore. 2.
In mycology, a universal veil is a temporary membranous tissue that fully envelops immature fruiting bodies of certain gilled mushrooms. [1] The developing Caesar's mushroom ( Amanita caesarea ), for example, which may resemble a small white sphere at this point, is protected by this structure.
The texture of the partial veil can exhibit specific characteristics which can aid in identification and these may persist in the ring once the cap has detached from it. These details may be similar to that of the cap surface or distinct from it. Texture/surface descriptions include: [12] Thick - a ring with thick, often sturdy flesh.
(1) is the universal veil, the outer layer protecting the developing basidioma; (4) is the volva, the remnant of the universal veil at the base of the basidioma. In mycology , a volva is a cup-like structure at the base of a mushroom that is a remnant of the universal veil , [ 1 ] or the remains of the peridium that encloses the immature fruit ...
The generic name is a compound Ancient Greek word hēbē (ἥβη), "youth" or "puberty" and the suffix -loma (λόμα), a fringe (pertaining to the fungal veil).Thus, Hebeloma translates as "fringe of youth", in reference to how the fungal veil is only seen in immature specimens.
