Minnesota Lichens
Composite Organism |
Lichens are composite organisms, not individual organisms. They do not form a taxonomic group, but are found in separate lineages. They are composed of a fungus (mycobiont) and a photosynthetic partner (photobiont), usually either a green alga or a cyanobacteria. Lichens are often referred to as “lichenized fungi.” They take their scientific name from the fungal component. There are 14,000 to 20,000 species of lichens in hundreds of genera. There are about 20,000 known species of lichens worldwide, at least 5,823 species in 805 genera in the continental United States and Canada, and at least 456 species in Minnesota. |

Powdered Sunshine Lichen |
||
Powdered Sunshine Lichen (Vulpicida pinastri) is an easily recognized, widespread, and very common lichen. It occurs in northern forested areas around the globe, including Europe, Asia, and North America. It grows on the bark of conifers and birch. It is usually found no more than chest high, probably protected under snow from desiccation by winter winds. The vegetative body is leaf-like and divided into lobes. When growing on flat surfaces, the lobes are short, and it forms a flat rosette. When growing on thin branches, the lobes are longer and more erect. The upper side is greenish-yellow or yellowish-green in sunny locations, grayish-green in shaded locations. The margins are densely covered with bright yellow reproductive granules, giving them a powdered look. This is the feature that gives the lichen its common name. |

Boreal Oakmoss |
||
Boreal Oakmoss (Evernia mesomorpha) is a common and widespread shrubby lichen. It occurs across the globe in the northern latitudes. In the United States it is restricted to the northern tier of states. In Minnesota it is common in the northern third of the state, very common in the Arrowhead region, with only scattered occurrences south to the Metro region. It is found in sunny sites in forests and woodlands. It grows on the branches of both deciduous and coniferous trees. It is relatively tolerant of pollution, which allows it to survive near urban areas. |

The vegetative body is shrub-like. It consists of numerous, loosely hanging, evenly forked branches. It looks something like an antler lichen but has broader branches. The branches are soft when wet, and pliable, not brittle, when dry. The upper and lower surfaces are green, wrinkled, and usually have abundant, coarse, granules. These granules are the main form vegetative reproduction. Sexual reproductive structures are rarely produced. Boreal Oakmoss is not edible. Handling it may cause severe dermatitis. |

Bristly Beard Lichen |
||
Bristly Beard Lichen (Usnea hirta) is a very common shrubby lichen, It occurs throughout Europe and the Americas. It is common in northeast and north-central Minnesota, very common in the Arrowhead region, but completely absent from the remaining two-thirds of the state. It is found in coniferous and mixed forests growing on the bark and twigs of sick or dying coniferous trees, rarely also on birch trees, very rarely also on rock. Bristly Beard Lichen is pale, grayish-green, yellowish-green, or blackish-gray, and is variable in shape. It may appear as a few long drooping strands; an erect, densely branched, shrub-like tuft; or a combination of the two. |

The main branches are unequal in length and have numerous short side branches. They are usually short, erect, and stiff when dry, limp when wet. Drooping branches, if present, are long and contorted. All branches are angular, not round, in cross section, are swollen at the base, and are often broadly forked. The base of each branch is the same color as the rest of the branch, not blackened. The surface is dull to shiny and never cracked. |
||
Sinewed Bushy Lichen |
||
Sinewed Bushy Lichen (Ramalina americana) is widespread and very common. It occurs in the eastern deciduous forests of the United States and southern Canada, and in the mountainous forests of Mexico. In Minnesota it is very common in the north, scattered to absent in the south. It is found on bark of old hardwood trees, usually in full sun, mostly on twigs and branches in the upper canopy but also on the trunk. It is more sensitive to air pollution than most lichens, and is absent from areas with even mild air pollution. |

|
Sinewed Bushy Lichen appears as a short, shrubby, yellowish-green tuft. The branches are narrow, straight-sided, flattened, solid, and strongly ridged and channeled. Yellow, disk-like, spore-producing structures are frequent and large. They appear at or close to the tips of the branches. They are usually flat but often contorted. |
||
Hooded Sunburst Lichen |
||
Hooded Sunburst Lichen (Oxneria fallax) is a widespread and very common lichen. It occurs throughout Europe and across North America, and is very common in Minnesota. It grows on bark on the trunks of hardwood trees in humid to moderately dry conditions. It forms rosettes up to 1½″ in diameter that often fuse together into large colonies. Hooded Sunburst Lichen is leaf-like and divided into small lobes. It is deep orange where exposed to the sun, orangish-red to reddish-orange in partially shaded areas, and pale greenish-yellow in deep shade. |

Tiny, crescent-shaped slits, are formed on the margins at the tips of the lobes. Within the slits powdery, greenish-yellow clusters of cells are produced. The cell clusters are dispersed by wind and rain, and can form new rosettes when they land on a suitable surface. Disk-like, spore-producing structures are rarely produced. When present, the disks are stalked, orange, up to ⅛″ in diameter, and shaped like a plate. Each disk has a ring of tissue around it that resembles the tissue of the lobes. |
