What You Should Know
Clitocybe squamulosa is a clitocyboid mushroom that appears under conifers, primarily in northern and montane North America. It is often associated with snowbanks, and can be distinguished by a brown to brownish orange, depressed to infundibuliform cap and stipe, yellowish-white decurrent gills, smooth spores, and habit in duff under conifers. Despite the scales are not always present and, if so, are usually small and concentrated only at the disc.
