Veil (mycology)

The velum ( German cover) is a thin membrane that in the class of Basidiomycetes mushrooms huttragenden before Sporenreife the entire fruiting body or only the spore-bearing parts ( hymenophore ) surrounds.

There are two types of the velum: The universal veil (total cover) is a thin membrane that grows completely around the stem and hat, so it stretches from the tip of the hat to the lower end of the handle. She tears up at maturity. The bowl-shaped remains at the base, in this case, " vagina " ( volva ) called and sometimes confused with a " tuber ".

The velum partiale (partial cover ), however, is a membrane that in some young cap fungus only the spore-bearing parts covered, so it stretches from the brim to the upper end of the handle. When they mature mushroom bursts and often remains on the brim as a " cuff " (annulus ) on the stalk or " veil " ( Cortina ).

Both types can also be present at the same time, such as when flying fungus. Here are the remains of the universal veil on the hat and at the base, and it is also a collar visible partiale a remnant of the velum.

The velum or its remains are a very important macroscopic feature for distinguishing fungal species.
