Description: Pileus 10-20 mm diam., hemispherical or convex when young, becoming pulvinate or flat, margin always strongly incurved and connected with the stipe, never exposing the gleba: smooth, near or at the margin grooved by deep radially arranged channels; whitish or pallid argillaceous; viscid, in dry condition velvety, no veil remnants visible. Gleba consisting of tortous more or less radially orientated canals, sometimes becoming indistinctly lamelliform; whitish, later turning brownish: strongly gelatinised. Stipe 7-15 x 4-10 mm, clavate or marginate. attenuated towards the apex, columella always distinctly developed, edge or marginate base connected with margin of pileus; concolourous with pileus, viscid, veil remnants absent, basal rhizoids lacking. Context yellowish turning brown, strongly gelatinised. Smell and taste not distinctive. Chemical reactions on pileus: KOH—brown.
Spores 9-11 x 4.5-5.5 µm, oval or elliptical, smooth, yellowish-brownish, membrane thin-walled, with distinct germ pore, bilaterally symmetrical. Basidia not observed. Chrysocystidia 40-60 x 12-16 µm, fusoid or lageniform, with thin-walled hyaline membrane, in KOH with yellow plasmatic pigment. Cuticle a cutis composed of repent, cylindrical, gelatinised hyphae (2-5 µm diam.), membrane encrusted by brownish pigment, clamp connections present.
