Rolueckia

Rolueckia is a small genus of leaf-dwelling lichens in the family Gomphillaceae. It forms thin, pale green-grey films on the living leaves of tropical forest plants. Established in 2008 by Thai lichenologists, this genus is distinguished by its unique reproductive structures—tall, reddish-brown bristles called hyphophores that produce tiny rod-shaped propagules for asexual reproduction. The three recognized species share similar microscopic fruit bodies called apothecia that contain exceptionally small, few-segmented spores, but can be differentiated by their specific spore patterns and the presence or absence of sterile bristles. These specialized lichens grow exclusively in the humid, shaded understory of tropical rainforests where consistent moisture protects them from drying out....read more on Wikipedia.
