text: # Aspidothelium lueckingii
  
  Aspidothelium lueckingii is a species of corticolous (bark-dwelling) in the family Thelenellaceae. Found in mountainous cloud forests in Bolivia, it was formally described in 2009 by lichenologist Adam Flakus. The type specimen was collected near Incachaca village (Chapare Province) at an elevation of 2,317 m (7,602 ft), where it was found growing on the bark of a pine tree. It is known only from the type locality. It is named in honour of German lichenologist Robert Lücking, "for his magnificent contribution to the knowledge of tropical lichens."
