Collar (mycology)

Hat mushroom with collar in longitudinal section

The collar swindler with lamellas attached to the ring-shaped collar

Collar or Kollar ( collar , of medium latin collaris = scarf ) referred to in the Mycology a Cap flesh lying in a fungus annular collar which separates the slats from the stalk.

In the case of leaf mushrooms , collar is understood to be a ring-shaped structure at the attachment point of the lamella, which separates the lamella from the stem. The lamellae are fused together shortly before the stem in such a way that the stem is enclosed by a "collar" at the level of the lamellae, but it does not touch the stem.

Detached, ring-shaped structures at the base of the stalked endoperidia of earth stars are also sometimes referred to as collar. Such a structure occurs, for example, in the ruff earth star ( Geastrum triplex ) and in the collar earth star ( Geastrum striatum ).
