The fragile and pale argillaceous carpophores, the earthy to farinaceous smell, the encrusted cuticular hyphae, the clamp connections on the septa, and the conspicuously small 5-angled spores are distinctive characters of E. imbecille. The material gathered on the Solomon Islands agrees in all essential details with the typic collections from New Zealand.

This striking species is named after the late New Zealand mycologist R.F.R. McNabb who twice gathered material in the surroundings of Auckland, New Zealand.

Typus PDD 30272.

Material. - New Zealand: New Plymouth, Pukekura Park, 10.VI.1968, leg. Horak (PDD 27045, holotype).

Habitat. - On soil in forests. - New Zealand.

Illustrations. - Horak (1973:61).

The small (pileus -7 mm diam.) and fragile carpophores and the deep yellow colours are distinctive for this New Zealand species. The lamellae bear clavate cheilocystidia and the clampless cuticular hyphae are encrusted with the yellowish pigment. For further discussion see Horak (1973:61).

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).

Typus PDD 27146.
