Biologists Announce Discovery of an Entirely New Branch of Life

In further proof that we never know just how much we don’t know, a paper published in Nature suggests that biologists in the UK have discovered an entirely new and unique branch in the tree of life. A group of mysterious microscopic organisms related to fungus are actually so different that they make up their own kind of fungal group. Another way to say that: there are so many of these distinctly different kinds of organisms living in so many diverse places, that the biodiversity among this new group might be as vast as the entire known fungal kingdom. In fact, they might not actually be fungi at all.
The scientists who have discovered this new clade--a clade is like a branch on the tree of life that consists of an organism and all of its descendants--have named it cryptomycota, which loosely means “hidden from the kingdom Fungi” so we’re told. And indeed the cryptomycota have remained hidden from sight even though it turns out they are everywhere, living in many different environments, including freshwater lakes and sediments, as well as pond water.   link
