This lava has flowed to the surface through some horrible accident. Stepping into it will deal lot of damage to your feet and legs. Lava (and magma) can be used to cook as a substitute for a nearby fire.

If you see this message going down, don't descend. You will die. It means there is lava on the floor below, which usually also means there is no stair going up.
