Descriptions
Pileus -40 mm, hemispherical when young, soon becoming broadly campanulate finally convex to plane with distinct papilla; margin strongly inrolled in young specimens; white turning pale argillaceous or pale ochre in aged basidiomes; viscid to glutinous when moist, minutely fibrillose in dry condition, margin non-striate. -Lamellae 12-18 (1-3) arcuate to broadly adnate and decurrent with long tooth, crowded; whitish, occasionally with faint orange tint, edges concolorous, entire. - Stipe 25-90 x 26 mm, cylindrical or attenuated towards base, often robust in young specimens; concolorous with pileus, pale ochre-pink in lower portion, especially at base; dry, conspicuously fibrillose, solid becoming fistulose-hollow, single or caespitose. - Context pale whitish or ochre in pileus, pale brown to pink towards base of stipe, soft. - Odour and taste not distinctive. - Chemical reactions on pileus: KOH - pale yellow. - Spore print white. Spores 8-9 x 5-6 um, ovoid to elliptical, smooth, hyaline, inamyloid. - Basidia 45 60 x 6-7 um, 4 spored. -Cystidia absent. -Pileipellis an ixocutis of cylindrical, interwoven, gelatinised hyphae (2-6 um diam.), pigment not observed; clamp connections present (Pl. 1, Fig., 7),
DISTRIBUTION: NZ (NA).
ECOLOGY: Rare; saprobic on soil among litter under Leptospermum scoparium. June.

ETYMOLOGY: impurus = off white, dirty.
Macroscopically Camarophyllus impurus is similar in many respects to C. patinaecolor. The basidiomes of both taxa are characterised by white to off-white colours. C. impurus, however, does not exhibit greenish-blue tinges which is a typical feature of C. patinaecolor. Microscopically the identification of the two related taxa is readily established because - their spores differ clearly in size.
TYPE: NZ: NA, Waitakere Ranges, Mill Bay, under Leptospermum scoparium, 29 vi 1981, Horak, PDD 27226.
