P. 10-20 mm, hemispheric or convex when young becoming plane, centre often depressed to subumbilicate in overmature specimens; white or pale grey-brown with distinct blue tinge; dry, estriate, not hygrophanous, coarsely fibrillose, sometimes concentrically zonate, often rimose and split towards margin. L. 8-16(-3), adnate to adnexed, emarginate in mature carpophores, ventricose, -5 mm wide: whitish to pale argillaceous with blue tinge, becoming argillaceous-pink, edge concolorous, even. St. 30-60/1,5-2 mm, cylindric, slender, equal; grey-blue, white towards the base to which conspicuous white rhizoids or strigose hairs are attached; dry, smooth at apex, coarsely fibrillose to hairy towards base, fistulose, single in groups. Context blue, especially in upper-portion of stipe. S farinaceous or spermatic. Sp. 9-12/5,5-6 µm, multiangled. Bas. 30-38/7-10 µm, 4-spored. Ch. and pl. absent. Cuticle a cutis of repent, cylindric hyphae (5-15 µm diam.), hyaline, thin-walled membrane, with brown PE, - OH, - CC.

Habitat. - Among moss (Sphagnum) in swamps. - New Zealand.

Pileus -20 mm, convexus dein planus, saepe centro depressus aetate, albus, griseo-brunneo-azureus tinctu, conspicue fibrillosus. Lamellae adnato-emarginatae. Stipes -60/-2 mm, cylindricus, pallide azureus, mycelio albostrigosus. Caro farinacea. Sporae 9-12/5,5-6 µm. In locis paludosis. Nova Zelandia.

In New Zealand this is a very common species in swampy localities called "pakihi". Apart of its peculiar habit this fungus is immediately recognized by the pale blue coloured pileus and stipe and the multiangled spores which remind of those known from Rhodocybe (Horak 1979c, 1979d).
