In wet, rainy weather, the stratum is soft-skinned, in dry weather-hard, brittle, brown. Cetraria, like other lichens, is a kind of complex organism consisting of fungal filaments and microscopic green algae. Height (length) up to 10 cm.

The part used. Thallus of the lichen (whole plant).
The time of gathering. In the course of a whole summer.
The plant contains lichenin and other carbohydrates extracted with hot water and forming a gel, sugar (glucose and galactose), proteins (0,5 – 3%), fats (1 – 2%), wax (1%), vegetable gum, pigments (up 6.8%), mineral salts (1 – 2%), cyanocobalamin (vitamin B12), strongly bitter substance cetraric acid(2 – 3%) and a number of lichen acids: protoliterate, paraliterary, protocerebrum, fumaropimaric, usnic, which have antibiotic properties.
