The agarics fruiting in natural and anthropogenic disturbed habitats are considered. The early colonists of such environments are species either able to utilise ephemeral resources or able to move nutrients quickly from one source to another. A suite of micro-characters uniting the species concerned is given. Attention is drawn to those agarics recorded from burns in various parts of the world, and from arctic-alpine areas. The concept of a geomorphological escalator is explored.
