One Leaf Ramalina (Ramalina unifolia), a Wisconsin Special Concern lichen, is found on conifer or, more commonly, deciduous twigs.

 
 
 

One leaf ramalina is a folios lichen with abundant apothecia abundant that are laminal and marginal, up to 12mm wide. Discs are pruinose. The thallus is a single, fan-shaped lobe forming almost a circle, becoming up to 12cm broad, usually much less, flat, dark- to lime-green, and is ridged with pseudocyphellae.

It can distinguished from other Ramalina species by its single-lobed thallus. It is most similar to the more common R sinensis, but the thallus of that species is more branched and rarely has any laminal (not marginal) apothecia.

Soredia and isidia are absent.

One leaf ramalina is found on conifer or, more commonly, deciduous twigs.

Associated species include quaking and big tooth aspen, ash, basswood, oak, and red pine. This lichen is usually found in the tree canopy and, therefore, is most likely to be seen on fallen twigs on the forest floor.

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
