 Although the majority of species are found growing on the dead wood of various conifer and hardwood genera, some are known to grow on the dead fruit bodies of other polypores.For example, "S. brevispora" feeds on "Phellinidium ferrugineofuscum", while "S. chrysella" eats "Phellinus chrysoloma".The tropical Chinese species "S. bambusicola" grows on dead bamboo.
