Mycoid

Mycoids are a fungoid species of spacebourne organisms which feed on the fabric of space, excreting an angstrom-thin pure energy "string" that stretches on for light years. Mycoids reproduce when their spores land on a warm planet with a thick atmosphere and begin producing a Habitat Modifier known as Mycomass, which aims to convert all organic material into mycomass and eventually mycoids. Even higher dimensional beings can be threatened by the process, as Yompu learned the hard way. While mycosation of a planet is irreversible, new organisms can eventually evolve on the surface of a mycoid world.

Applications
The strings produced by mycoids can be used for instantaneous interstellar travel, although this can be potentially lethal. Only the four most safe mycoid strings are used in any frequency. Waks have developed artificial strings as a substitute for mycoid strings that does not involve the threatening organisms, this technology is also the basis for the sub-net communication web.

Benign mycomass is used in the highly invasive creation of Mycoborgs.
