     This mycorrhizal fungus is often found growing among hardwoods such as oak and beech trees, and coniferous trees such as pine. The distinctive toothed underside of the mushroom is where brown spores ranging from 5-7.5µm are released. Another characteristic trait is the brown to black hairy to scaly cap surface. This mushroom is quite bitter tasting and rather unpleasant. 
     Identifying this mushroom to species can be rather daunting as there are several similar looking species in this genus. S. scabrosus and S. imbricatus are easily confused with S. squamosus. Furthermore, there is debate on whether the North American species is the same as the European species. In Europe this fungi is commonly associated with Pine, whereas in North America it tends to be more associated with hardwood trees.
