British Soldier Lichens or Red Cap Lichens are very common Cladonias found all over New England. On my way out from visiting Roaring Falls yesterday I came across a spot covered with them. I particularly liked this stump that was home to quite a few.
For a closer look see my post from April 7. Mark Graf was wondering on Tom Whelan’s posting of these about the development of the red caps. These are fruiting bodies and there has been conjecture as to what the red function might be, but I am not sure whether anyone has come up with a definitive explanation. Whatever it is, those caps make it a very distinctive sight in woodland ecology.
