It's that time of year when our eyes start to look down more as the trees become bare. But what diversity there is to behold amongst the rotting leaves and dead branches. This lichen and also the moss along the river was looking wonderful, but I don't know what it is, so if anybody can help me that would be great..
Second & third photo may be Flavoparmelia (Green Shield) which is a lichen of your area, not so much mine :-) Fourth photo includes Flavoparmelia but also has a few other species including something like a Melanohalea (Camouflage) or similar genus.
Somewhat off the specific topic here, but that implies that there are three or four species in that photo, which surprised me so much that I thought I should read a little something about lichens. I started with a google search of images, found myself on this (US) National Park Service which packs a lot of interesting information on Arctic lichens into a very short read: Lichens of the Arctic (U.S. National Park Service). We do have some information sources on the Fungus and Lichen Resources on the Web and in Print resource page.
Thankyou Wendy. I have visited this resource, I don't know about you but I find the information on the 'forum' about fungi and lichen especially from @Frog to hit the mark brilliantly. Not laziness on my part, but I find this such a specialist subject.
