"Slime molds, as a group, are polyphyletic. They were originally represented by the subkingdom Gymnomycota in the Fungi kingdom and included the defunct phyla Myxomycota, Acrasiomycota, and Labyrinthulomycota. Slime molds are now divided among several supergroups, none of which are included in the kingdom Fungi." Wikipedia George Barron's great fungi guide (1999) has this to say about slime moulds: they are "composed mainly of a slimy mass of protoplasm called a plasmodium. Most of their lives, slime moulds are hidden inside well-rotted logs or stumps, or buried in leaf mould. When it's time to fruit, however, they migrate to a better site for spore dispersal. The plasmodium can travel several feet and climbs any object, living or dead, that gives it a site advantage." So think of this next time you are looking at what seems an innocuous slime mould! These things can move and climb!
