This white spored mushroom is a common species in our area, fruiting on the ground in litter under plants and along trail edges during much of the growing season. The mushrooms often arise from white threads that bind the substrate into a mat. The fruit bodies are rather tough and long lasting, and are capable of drying and then re-hydrating to their natural size. Fresh mushrooms have brownish colors with yellowish tones on the gills and upper stipe and a peppery taste. Older specimens are often lighter in color and the lower stipe is often covered with matted fibrils.
