Cortex (mycology)

from Wikipedia, the free encyclopedia

The cortex or cortical layer is a mostly more or less thin layer, often clearly recognizable with a magnifying glass, made of very tightly interwoven and often stuck together (agglutinated) hyphae . It is located in the upper part of the trama and forms a kind of bark from which the hair of the hat felt ( tomentum ) often emerges . As a rule, it is darker, often yellowish red, brown or blackish in color. After the hat surface has been baked, the cortical layer can form a thin, crusty hat surface. The presence or absence of a cortical layer is an important determinant , especially with non-leaf mushrooms (Aphyllophorales). A cortex layer can be found, for example, in the layer fungi ( stereum ), amylostereum and laurilia , as well as in many other genera.

In general, the bark layer on the surface of the hat or handle is also called the cortex.
