Some of the trees here appear to have rough brown hair draped from their branches.
This is a type of lichen, specifically one from the genus Bryoria. Some Native American tribes have stories about how Coyote got stuck in a tree and had to cut off his fur to get free, creating this lichen in the process. There are very few lichens that are regularly eaten by people, but this one is, or at least was. Native people collected the long, brown clumps of strands, washed and soaked them, and cooked them into loaves in pits.
Can’t say I’ve tried it myself. But the hairy brown clumps in the conifers are impossible to miss.
Remember: lichen is an association between a fungus (providing structure) and an algae (providing photosynthate, that is, food). As many of my former students could tell you, there is a handy joke for remembering this. Would you try lichen loaf for dinner if someone offered you some?
