Material examined: Holotype (PDD 29508) : New Zealand, Auckland, Piha, Kitekite Falls, 17. V. 1971, leg. DINGLEY - PDD 29026: New Zealand, Auckland, Sharp's Bush, 25. IV. 1971, leg. DINGLEY.
Pileus 20-40 mm diam., up to 40 mm high, conical, papilla always sharply conical, margin not inrolled; mouse grey, drying paler, apex yellowish in aged specimens; innately fibrillose, not striate, dry. Lamellae free or adnexed, ventricose; grey when young then turning pink, edge concolorous, even. Stipe 40-80/4-7 mm (-12 mm at the base), cylindrical or attenuated towards the apex, twisted; mouse grey, paler towards the whitish villous base; hollow, brittle, dry, single. Context grey, without bluish or greenish tints. Odour and taste unknown. Spore print brick red. Spores 7,5-11 mµ, cuboid. Basidia 40-50/10-12 mµ, 4-spored. Cheilocystidia (and pleurocystidia) 45-80/10-13-mµ, fusoid, several times constricted (like an hour glass) towards the conical apex, hyaline, thin-walled, without pigment. Cuticle a cutis composed of cylindrical repent hyphae (6-12 mµ, diam.), plasmatic pigment present. Clamp connections numerous.
Habitat: On soil under Leptospermum ericoides. New Zealand.
Pileo usque ad 40 mm lato, conico, cinereo, sicco. Lamellis subliberis. Stipite -80/-7 mm, cylindraceo, pileo concolori. Sporis 7,5-11 mµ, cuboideis. Cystidiis ad apicem constrictis. Ad terram in silvis. Novazelandia.
According to the microscopical and macroscopical characters this species is closely related with E. virescens (B. & C.). The young and fresh fruitingbodies of E. canoconicum, however, do not even show traces of bluish or greenish colours. The cystidia of that taxon are also quite different from those of E. virescens (B. & C.). For that reason it is unlikely that E. canoconicum could be interpreted as a pale and washed out E. virescens (B. & C.).
Typus (PDD 29508): Piha, 17. V. 1971.
Material examined: Holotype (PDD 30274) : New Zealand, N of Auckland, Hobson Co., Waipoua Forest, 16. IV. 1972, leg. DINGLEY.
Pileus up to 35 mm diam. convex or indistinctly campanulate, without conspicuous umbo or papilla, old carpophores plane; cinnamon brown to brick red with radial buff to rosy buff streaks; dry glabrous to slightly fibrillose or hairy, striate hygrophanous. Lamellae free to adnexed ventricose ((-5 mm wide), distant; cinnamon when young turning brick red. Stipe 50-90/3-4 mm cylindrical or attenuated towards the apex, rosy red with touches of brick red, base white; fibrillose dry hollow fragile single. Context pale brownish to brick red. Odour and taste not distinctive. Chemical reactions unknown. Spores 7-11 mµ, cuboid. Basidia 45-50/14-16 mµ, 4-spored. Cheilocystidia 50-70/8-12 mµ, fusoid with capitate apex sometimes several constrictions near the neck, membrane hyaline thin-walled, pigment absent. Cuticle a cutis of repent cylindrical hyphae (4-8 mµ diam.) plasmatic pigment present, membranes notgelatinized. Clamp connections numerous.
Habitat: On rotten wood of Agathis australis. New Zealand.
Pileo usque ad 35 mm lato, convxo-campanulato, e cinnamomeo lateritio. Lamellis subliberis. Stipite -90/-4 mm, cylindraceo, roseobrunneolo. Sporis 7-11 mµ, cuboideis. Cheilocystidiis fusoideocapitatis, apicem versus constrictis. Ad terram vel lignum putridum. Nova Zelandia.
Like the Malayan E. aurantio-album C. & Hg. this species also grows on rotten wood. The two taxa, however, are distinguished by the colours, the shape of the cystidia and the size of the spores.
Typus (PDD 30274) Waipoua, 16. IV. 1972.
Material examined: Holotype (PDD 27012): - ZT, Herb. HORAK 74/134: Rancho Hambre, Valle Tierra Major, Tierra del Fuego, Argentina, 3. III. 1974, leg. HORAK.

Description of the Fuegian collection

Pileus -12 mm diam., hemispherical to convex, white, aged specimens turning pink, covered with silky appressed fibrils, not striate, dry, membranaceous. Lamellae (L 5-6, l 1) emarginate adnate, ventricose, gill edge concolorous. Stipe -20/-1,5 mm, cylindrical, often bent towards the base which is covered with fibrillose white squamules, pruinose towards the apex, white, fragile, dry, single in groups. Context white. Odour and taste not distinctive. Spores 6-8 mµ, cuboid to quadrate. Basidia 30-40/10-12 mµ, 4-spored. Cheilo- and pleurocystidia absent. Cuticle a cutis of repent cylindrical hyphae (4-10 mµ diam.), membrane encrusted with pigment. Clamp connections present.

Habitat: On rotten wood or on soil in wet localities in broad leaved forests and Nothofagus forests. New Zealand (type), Tierra del Fuego (Argentina).
The collection from Tierra del Fuego corresponds well in all essential characters with the type from New Zealand. The small white fruitingbodies are easely overlooked for they grow preferably among debris in wet localities hidden by lush herbaceous plants.
