Hooded rosette lichen
During the lab, I observed the hooded rosette lichen (a foliose lichen) which is a part of the Physciaceae family and Physcia genus. This type of lichen is very common and is seen along the east and west coasts of North America. It usually has a pale grey or green colour to it (sometimes yellow) and appears on twigs and tree bark or walls and sometimes on rocks. A lot of the time lichen grows flat against their surface but this lichen does not. It has uneven branching patterns and thickened branches.
