These little orange spots are spore-producing regions of a fungus that causes a canker disease of wood. The wood in this case is a root protuberance in the pathway, undoubtedly constantly stepped on and otherwise stressed. The fungus took advantage of the broken and worn wood to grow inside as a weak parasite. The fungus is known as coral spot Nectria cinnabarina*, for the colorful spore-bearing wounds it causes.
*Cinnabar-colored (orange) killer.
