Sticta is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species.[2] These lichens have a leafy appearance, and are colored brown or black. Sticta species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens.[3]

Description

The vegetative bodies of the Sticta, the

apothecia (cup-shaped spore-bearing structures) are rarely found. Sticta species are usually found growing on bark, wood, or mossy rock.[4]

Photobiont partners of Sticta species include members of the green algae genera Chloroidium, Coccomyxa, Elliptochloris, Heveochlorella, and Symbiochloris.[5]

The

liverwort genus Monoclea contains lichen-like organisms completely unrelated to, but readily confused with Sticta.[6]

Distribution and habitat

Sticta species are primarily

tropical in distribution, but some species have been reported from as north as Norway,[7] and as far south as the southern tip of South America.[8]

Most species of Sticta grow on bark, wood, or mossy rock, usually in humid areas.[4]

Phylogenetics

monophyletic.[9][10]

Indicators of ecological continuity

Some

canopy continuity.[11] The presence of these species is a reliable indicator that the forest has existed back to early medieval times, without being clear-cut and regrown. Two Sticta species, namely, S. dufournii or the blue-green algal morphotype S. canariensis, are among several species of lichens that may be used to calculate the New Index of Ecological Continuity (NIEC), considered the most sensitive and accurate determination of forest continuity.[12]

Bioactive compounds

A comprehensive comparative study on the antioxidant activity of lichens from Hawaii and Iceland revealed the Hawaiian lichen S. weigelii to be a potent producer of antioxidative compounds.[13]
