Verdigris Navel
Small and not often encountered, this species is an inhabitant of moss in nutrient-poor gravelly or sandy soils. The dry caps are under an inch across, and shallowly to deeply umbilicate, with margins that are ribbed and initially inrolled but becoming uplifted in age. Caps have a somewhat coarse surface, with colors that range from deep blue to turquoise to bluish green, fading to gray-green in age. The gills are decurrent, widely spaced and thick, intervenose with numerous short gills. The stipes are equal and under two inches, concolorous with the cap, smooth, dry, and in age hollow. The flesh is thin and bluish. There is no distinct odor and the taste is mild. Edibility is unknown. In the PNW it is most likely to be encountered in winter or early spring. With its blue to greenish cap it is not likely to be confused with any other species.
