Icmadolphila ericetorum, a.k.a. ‘Fairy barf lichen’
James and his merry band of ne'er-do-wells spent the weekend measuring and recording riparian degradation in Ladyfinger Gulch, up in The Hills. He sent me this photo of Fairy Barf lichen, one of the species they found and noted, because I'm a hands and knees naturalist. He also sent a high recommendation for the Ken Burns' History of our National Parks on PBS being shown on PBS this week. If you're going to sit on the sofa anyway, at least watch something that will move and inform you.
(Icmadolphila ericetorum was caught by my spellcheck, but it did not give an alternative spelling. How else could you spell Icmadolphila ericetorum? It's spelled just like it sounds.)
