Trail from White Wolf to Harden Lake

Dog vomit slime mold is always an exciting find along the trail! Plasmodial slime molds like this one are actually sort of an enormous single cell with thousands of nuclei that formed when individual flagellated cells swarmed together and fused. They move along in an amoeboid fashion in search of nutrients. If you're moving faster than a slime mold down Yosemite trails, you might walk right by some of the park's most fascinating inhabitants!
