Teaser Answered A big thank you to Deedee Burnside for identifying the above Tuesday Teaser as Reindeer Lichen. More on Reindeer Lichen here.
This looks more like a coral fungus than a reindeer lichen. The color and structure don’t seem right for reindeer lichens, and I would be surprised to find one in an urban environment. But who knows… I would be happy to look at a closer photo or a specimen to check.
