A medium-sized green, slimy woodland mushroom. The cap is convex, broadening, and becoming umbonate with age, ± 5 cm in diameter. At first it is vivid blue to green, very glutinous, slimy, with a sprinkling of white veil remnants around the edge. Later the colour fades, becomes yellow ocher. The stem is quite long and of uniform thickness. It has a fragile brown, black ring, and below this the stem is covered in fine white scales, or flakes. The gills are initially white, then clay-brown, and sometimes have a white edge. The spore print is brownish-purple. It has oval spores.
