Catillaria Chalybeia Lichen

The Catillaria Chalybeia lichen looks like tiny black dots usually found growing on top of other rock lichens. The black dots are very small, ranging from just 0.15 mm to 0.5 mm in diameter. The rims on Apothecia are narrow and black in color, the discs may be black also, but are usually a dark grey with a flat surface. Apothecia are scattered widely across the rock and are rarely found in clusters. Read More….

Look for it on inland rock bluffs, along trails, and on trees, it is also quite common on boulders along lakes and streams. It is quite common on the BC coast. They are a leaf lichen. The lobes of the thallus are up to 4 mm in diameter and flattened down.  Read More….

 

 

Cumberland Rock Shield

The Cumberland Rock Shield Lichen is a grey to green lichen which is found across much of North and South America. It can be found in all the Pacific Northwest. It is a relatively large lichen and grows on rocks, where it is tightly attached and impossible to remove. They can grow to 30 cm across the colonies can be of various shapes.  The lichen is divided into deep irregular shapes near the center and often have a black edge.

Golden Moonglow Lichen

The Golden Moonglow can be found on rock bluffs and boulders. The golden moon glow lichen is a small round lichen. It usually is no bigger than a dime but noticeable because of the way the dark, disc-shaped fruiting bodies in the center turn greenish-yellow outer edges. One unusual aspect of this lichen is its squamulose form. A squamulose lichen falls somewhere between the leafy foliose lichens and crusty crustose lichens and has tiny, curled lobes around its outer edges. Read More….

 

 

Lipstick Cladonia Lichen

This is lipstick Cladonia Lichen, one of my favorite lichens. The Lipstick Cladonia is actually a symbiotic growth of fungi and algae. It is found on dead wood, the base of trees and on rocks. It grows in temperate to boreal regions all over the world. As you walk through our islands forests of the Vancouver Island, look down,  you just might see the tiny forests with their gardens of wonder.

Lobaria Oregana Lichen

Lobaria Oregana Lichen tends to break off and fall to the ground during the winter windy season here in Pacific Northwest. When they fall to the ground, they feed the forest. Forests have very nitrogen-poor soil environments and any added fertilizer is much needed. Without that nitrogen, the forest could not grow. Lobaria Oregana needs the trees to reach the canopy and as the lichen falls to the ground around the trees it adds its nitrogen to the forest floor, where it is absorbed by the trees.

Oak Moss Lichen

Oak Moss is a species of fruticose lichen that is valued for its oriental fragrance and as a fixative base. It grows throughout much of the Northern Hemisphere, in all of B.C. and on all parts of Vancouver Island. The pale greenish-gray thallus is up to 8 cm long and is palmately branched.

Petrigera Membranacea Lichen

The pelts are perhaps my favorite lichens. They come in such varieties and colors. Peltigera Membranacea  Lichen is also called the membrane dog lichen or just dog lichen. It grows all over the BC coast. Look for them on trees and rocks. Lichens can propagate themselves better through breakage and distribution of a part of the thallus, which contains all parts of the composite organism including the algae to the new environment.

Pincushion Sunburst Lichen

The Pincushion Sunburst Lichen is a very pretty lichen that grows all over the Pacific Northwest.  Found on dead and living twigs and in the axils of wide-spreading branches, quite often found on fruit trees and hardwoods. Shaded specimens take on a light yellow hue. The small yellow tightly knit clusters of apothecia help in its identification. Its Latin name is Xanthoria polycarpa. Read More….

 

 

Reindeer Moss Lichen

Reindeer Moss Lichen grows in arctic and northern regions around the world. It grows on the ground and on rocks. It looks like a green spongy moss and grows to be up to 10 cm high. The stems, or stocks, are hollow and branch out many times. Although it is called reindeer moss, it is actually a lichen. It grows on the whole coastal region of BC. Lichens are two separate organisms. They are made up of fungi and algae, which live and grow together.  Read More….

 

 

Rhizocarbon Oederi Lichen

The Rhizocarpon Oederi Lichen grows all over the Pacific Northwest. This crustose lichen forms large pale rusty color colonies on rocks near rivers and lakes. Sometimes the patches have darker brown tints in it and when growing in the shade they can take on a greenish color. Found along the coast on both granite and limestone rocks at the edge of small rivers or around lakes. Read More….

 

 

Shingled Rock Shield Lichen

Shingled Rock Shield Lichen is a foliose lichen commonly found on the BC coast. It is pale green with brown circular formations when young. The body of the lichen is composed of pale green leafy shaped structures. They are small and flat against the rock, not upright, although they can be pulled off. Young ones may be thinner and more curly while mature ones are wider and flatter. When they are in a young stage of life, roughly circular orange-brown craters will be present in the body. These fade and finally disappear with age. Read More….
