Description

''Teloschistopsis'' is characterized by a leaf-like ( foliose) to shrub-like (

) structure. This lichen is robust, predominantly grey in colour, but can have orange spots or take on a more yellowish to orange hue. The species ''Teloschistopsis chrysocarpoides'' is particularly notable for its leaf-like structure with hair-like structures on its upper surface and a fully cracked underside that reveals its inner layer. Most other species in this genus have a rounded exterior that is usually covered with a protective layer, devoid of hair-like structures. This protective layer has a complex cellular structure (known as "scleroprosoplectechymatous") and often features large, light patches. The reproductive structures of ''Teloschistopsis'' are in form. Its spores have a unique developmental process, are generally oval in shape, and have short to medium dividing lines (
