Ramalina subleptocarpha “Strap Lichen"
Fort Casey State Park, WA
December 17, 2013
Strap lichens in the genus Ramalina are relatively abundant and easy to recognize. Most grow on tree bark and have bushy bodies (i.e. a fruticose thallus)
with lots of long, flattened branches. This particular individual is densely covered in soredia (reproductive structures) giving it a coarse, bumpy appearance. This suggests that this individual is severely stressed by local air pollution.
