  I can't imagine finding lichens at night...I mostly find them deep in the woods. Posted 5 years ago

    No need to find them at night, you can take a sample during the day and take it home. When on a tree, you can slice off a piece of bark with lichen attached. Do this in the middle of the lichen and it doesn't kill the colony as a whole. Even less invasive is to look for fallen branches with lichens attached.
    
    I now got the post up so you can check whether it is worth a try:
