File talk:Mustard Powder Lichen sycamore.JPG

This photograph is misidentified. It is not the lichen Chrysothrix candelaris (Mustard Powder Lichen), but is instead a species of Trentepohlia (green algae, but in this case with orange pigment masking the chlorophyll). Silver lastdragon (talk) 22:49, 13 March 2013 (UTC)
