Cladonia subcariosa... By far - the smallest lichen I've ever found! From my height looking down, it looked like those little granules that wash off of shingled roofs. But where I found it, there were no shingles or roofs - which tells me to - look closer. Growing in a bare spot in the upper front yard, probably in very acidic soil - I got down on the ground to try to shoot it. It's easier to get down on the ground then it is to get up at my age. LOL!
