Cephaleuros

Cephaleuros (commonly known as red rust) is a genus of parasitic algae in the Trentepohliaceae consisting of about 14 species.

Description
Specimens can reach up to 10 mm in size. It is parasitic on some important economic plants from the tropics and subtropics including tea, coffee, mango, and guava, causing damage to the leaves with algal growth (algal leaf spot), or killing new shoots and disfiguring fruit. Cephaleuros may sometimes grow with a fungus to form a lichen that doesn't damage the plants.
