This liverwort (of the 'complex thallose' type) was growing on mud banks along a small stream in open serpentine country near chaparral along Bottle Rock Road, Lake County, California, on March 28th 2012. This piece was collected and photographed (still in in its micro-habitat) at at my house later. Thanks to Martin Hutten and Dan Norris for the identification.
