Coral slime (Ceratiomyxa fruticulosa) has a worldwide distribution and is one of the most common varieties of slime mold. It grows on rotting logs in shady, moist areas. I found this patch in the wooded ravine behind my home in southwest Washington State. The thread-like stalks were no more than a millimeter long.
