It is also known as Black Stone Flower. Dagarful is lichen growing in rosettes or irregularly spreading over the substratum giving the appearance of a flower – hence the name. It is mainly composed of fungal mycelia which form a network enclosing algal cells or gonidia. The plant is astringent, bitter, acrid, cooling, anti-inflammatory and aphrodisiac. This is one of the ingredients in making Garam Masala.
