Description
 
 

Common Antler Lichen occurs in the United States from Maine to Minnesota, adjacent Canadian provinces, and south along the foothills of the Appalachian Mountains. In Minnesota it is restricted to the northeast and north central regions. It grows in open comiferous and mixed forests on the bark of coniferous trees, especially pine, but also black spruce, tamarack, and white cedar.

The vegetative body (thallus) is 1½ to 4 (0.5 to 1.5 mm) wide and divided into overlapping, flattened lobes. It appears shrubby (fruticose) but it might be more appropriate to call it leafy (foliose). It is anchored to the substrate (bark) by a single central peg (holdfast). There are no root-like structures (rhizines). The lobes are long and narrow, 1 64 to 1 16 wide, with more or less parallel sides (linear). They are repeatedly branched, mostly with forked branches (dichotomously). The margins do not have a fringe of hairs. The upper surface is pale gray, smooth or wrinkled, shiny or dull, and lightly spotted. It appears somewhat rough due to abundant but minute granules (isidia). The lower surface is dark gray or black and broadly channeled.

Cup-like or disk-shaped fruiting bodies (apothecia) are rarely present.

Glossary

Apothecium

An open, disk-shaped or cup-shaped, reproductive structure, with spore sacs on the upper surface, that produces spores for the fungal partner of a lichen. Plural: apothecia.

 

Fruticose

Shrubby: referring to the growh form of lichens that may be tufted, draped, or stalked.

 

Holdfast

In lichens: A central peg-like projection of the thallus, like an umbilical cord, that anchors the lichen to the substrate.

 

Isidium

The reproductive structure of a lichen consisting of a cluster of algal cells (the photobiont) wrapped in fungal filaments (the mycobiont) and enclosed within a layer of protective tissue (cortex). Plural: isidia.

 

Linear

Long, straight, and narrow, with more or less parallel sides, like a blade of grass.

 

Rhizine

A root-like structure of a lichen that attaches the lower layer to the substrate.

 

Thallus

The vegetative body of a lichen composed of both the alga and the fungus.
