Holotype (K): 'Lake Rotoiti, N.Z.; leg. E. Kidson in Stevenson (1088), 16.V.1956'. - Herb. HK. ZT 67/224: 'Kopara, Ngahere, Prov. Westcoast, N.Z.; leg. Horak, 8.XII.1967'. - Herb. HK. ZT 68/474: 'Puponga, Prov. Nelson, N.Z.; leg. Horak, 16.V.1968'. - Herb. HK. ZT 69/190: 'Esk Burn, South Arm, Lake Te Anau, Fjordland, N.Z.; leg. Horak, 28.III.1969'.

Pileus 5-25 mm diam., hemispherical becoming umbilicate, egg yellow to lemon yellow or chrome yellow, fading to yellowish, glutinous, hygrophanous, striated at the margin, membranaceous. Lamellae broadly adnate to decurrent, concolorous with pileus, fading in age, distant, gill edge darker coloured, gelatinous thread present. Stipe 20-40 x 2-3(4) mm, cylindric, equal or attenuated below concolorous with pileus, but orange at the base, very glutinous throughout its entire length, hollow, single or fasciculate. Context yellow. Taste and odor not distinctive. Chemical reactions on pileus: KOH and HCl- negative. Spores 7-9.5 x 4-6 µm, ellipsoid, smooth, inamyloid. Basidia 30-47 x 6-7 µm, 4 spored. Cheilocystidia conspicuous, forming a gelatinous thread, terminal elements 30-50 x 2-6 µm, cylindric to clavate, hyaline, membrane strongly gelatinized, occasionally yellow plasmatic pigment present. Pleurocystidia absent. Cuticle a cutis of initially suberect later repent, gelatinized, hyaline hyphae (2-8µm diam.). Clamp connections numerous on cuticular hyphae.

On soil under Nothofagus spp. and Leptospermum spp. New Zealand.

Undoubtedly this species has close relationships to H. octayensis Singer (1962). Both taxa are deep yellow coloured and the pileus and stipe are coated with a glutinous layer; however, the Chilean species is of smaller size and the spores measure about 8.5-10 x 4.5-5.5 µm.

Pileus -30 mm, hemispherical to convex finally umbilicate at centre; yolk-yellow to lemon-yellow or chrome-yellow, fading to yellowish with age; glutinous, hygrophanous, striate at margin, membranaceous. - lamellae 8-16 (1 -3) broadly adnate to decurrent or arcuate; concolorous with pileus fading with age, edges greyish due to  gelatinous, separable thread. - Stipe 20-45 x 2-3 (-4) mm, cylindrical, equal or attenuated below, occasionally with swollen base; concolorous with pileus, turning orange at base in aged specimens; very glutinous, hollow, single or caespitose. -Context yellow, waxy. - Odour and taste not distinctive or slightly unpleasant. - Chemical reactions on pileus: KOH, HCI - negative. Spores 6.5-9.5 x 4-5.5 um, ellipsoid. - Basidia 30-55 x 5-7 um, 4-spored. – Cheilocystidia  conspicuous, 30-50 x 2-6 um, with cylindrical to clavate terminal cells, membrane hyaline, strongly gelatinised, occasionally with yellow plasmatic pigment. - Pleurocystidia absent. - Pileipellis an ixocutis of suberect, cylindrical hyphae (2-8 um diam.), membrane strongly gelatinised, with plasmatic pigment; clamp connections present (Pl. 1, Fig. 6).

ECOLOGY: Common; saprobic on soil among litter under Nothofagus (fusca, menziesii, solandri var. cliffortioides), Kunzea ericoides, Leptospermum scoparium or in broadleaved-conifer forests (Metrosideros umbellata, Podocarpus hallii, Dacrydium cupressinum), rarely on rotten wood. December-June.
