Byssoloma leucoblepharum thallus and apothecia.

To a greater or lesser degree all species of the genus Byssoloma have cottony or fuzzy margins. In the case of B. leucoblepharum the fuzzy margins lay flat on the thallus surface. The discs are brownish or purplish-brown. The thallus is granular and there is no color change when ultraviolet light is applied.
