Trypetheliopsis coccinea

Trypetheliopsis coccinea is a species of foliicolous (leaf-dwelling) crustose lichen in the family Trypetheliaceae. Originally described in 1993 as Musaespora coccinea, it was transferred to Trypetheliopsis in 2009 when that genus was resurrected and Musaespora was treated as its synonym. The lichen is highly distinctive, forming tiny greenish-grey patches densely covered with bright red warts and producing vivid orange-red, shell-shaped asexual structures called campylidia. Known only from a small area of lowland rainforest in Madang Province, Papua New Guinea, it grows on the leaves of understorey plants in shaded forest conditions....read more on Wikipedia.
