Reimnitzia santensis

About

Reimnitzia is a fungal genus in the family Graphidaceae. This is a monotypic genus, containing the single lichen species Reimnitzia santensis. Established in 2001 by the German lichenologist Klaus Kalb and named after his friends Michael and Christine Reimnitz, this bark-dwelling lichen is found in tropical forests across the Americas, Africa, and Asia. The species is characterized by its tiny, script-like fruiting structures with thick black borders and serves as an indicator of undisturbed, humid woodland due to its sensitivity to forest disturbance.
