Lamella (mycology)
As lamellae is called an in stand fungi occurring, spore-bearing structure, the hymenium (= layer in which the fruit cells are located). The lamellar hymenium is on the underside of the hat . Other non lamellige structures in fungi include spines ( Stachel fungi ), strips ( Leist Linge ), tubes ( Suillus ) or pores ( polyporus and others).
Another word for slats is leaves. So a group of typical lamellar supporting fungi is also agarics called.
In the case of the leaf or lamellar mushrooms, the shape of the fruit layer on the underside of the hat is more or less closely spaced and leaf-like. The lamellae can be unbranched, radial, branched or equipped with cross connections (= anastomoses). The surface of the lamellae is covered with cells ( basidia ), on the outside of which the spores are developed.
Taxonomic meaning
The color, the shape and the way in which the lamellae attach to the stem are characteristic properties that help to macroscopically identify a large mushroom .
colour
In some types of fungus, the lamellae have a typical basic color that is discolored by the ripening spores. For example, the basic color of the lamellae of the hair veils is often purple. Only later are they colored rust-brown by the spores.
shape
The following pictures describe the main types of lamellas. However, transitions between the forms are not uncommon.
forked
branched
with anastomoses
with lamellules
tight, crowded
far
Type of attachment to the stem
Another important feature is its attachment to the stem. In addition to the properties shown below, there are also the shapes: bulbous, curved, wavy, toothed, sawn, almost free, with collar ...
free
adnex or pinned
adnat or grown
cleaved
emarginate or fully booked
sinuate or descending with a tooth
subdecurrent
decurrent or declining
free: lamellas do not reach the stem. For example, typical for mushrooms agaricus and Scheidlinge
almost free: Between free and adnex
adnex: lamellae are less than half of their broad side attached to the stem
adnat: lamellae are attached to more than half of their broad side to the stem
emarginate: the attachment point of a lamella on the stem looks like part of it has
broken out or bitten out, running downwards: lamellas run down a shorter or longer piece on the handle. For example, typical of the genus clitocybe Clitocybe .
