Common Antler Lichen (Pseudevernia consocians), a Wisconsin Special Concern lichen, is found on tree bark in wet northern forests such as black spruce or white cedar swamps.
Common antler lichen is a foliose or fruticose lichen that usually is without apothecia. Its thallus is light gray above to darker gray or black below, lobes are linear, 1-1.5mm wide with forked branching.
It can be distinguished from look-alikes by its lack of cup-shaped apothecia and abundant, but minute, isidia, which give the lichen a fuzzy or ragged appearance.
Isidia are numerous, cylindrical, and sometimes branched.
Common antler lichen is found on bark in wet northern forests such as black spruce or white cedar swamps.
Associated species include black spruce, tamarack, white cedar, and ericads. Outside of Wisconsin it has been found on pine bark.
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.
