Dog Lichen

CAN BE FOUND IN:

Dog Lichen

Peltigera canina 

Appearance

The dog lichen has broad leaf lobes that are pale brown or grey with fine hairs thinly covering the leaves. The underside of this lichen has a cottony texture and is white in colour. The lower portion of the lichen that attaches to the soil flares out and is dark with brownish veins. 

Range & Habitat

This lichen is common throughout northern B.C. and can be found in open places on decaying wood matter, moss, humus, and mineral soils. 

Reciprocal relationships

Lichens can often be overlooked, but they contribute to ecosystem health like any other species! These beings grow along the forest floor, creating areas for insects to live and helping to stabilize the soil. Like other lichens, the dog lichen is a fungus so it reproduces in different ways. They produce different types of outgrowths, or balls, or saucer-like fruiting bodies that form new lichens when they get carried to new places by birds, wind, and water. 

Dog lichen grows in nutrient-poor and generally unproductive soil. However, they have the ability to fix nitrogen and thus contribute more nutrients to the soil. In this way, they can help foster areas where more plants can grow.
