The researchers used microscopic analysis of particles from the Pleistocene-Holocene sediments collected from the California Channel Islands and compared them with modern soil samples that had been subjected to wildfires, as well as balls of stringy fungal material, called sclerotia, some of which were also subjected to a range of temperatures in a laboratory.
