Collections Examined

Holotype (K): 'Keith George Park, Wellington, N.Z.: leg. Stevenson (606), 30.V.1949'. - Herb. HK. ZT 68/549: 'Lucy's Gully, Kaitake Range. Mt. Egmont, N.Z.; leg. Horak, 14.VI.1968'.

Description

Pileus 15-25 mm diam., hemispherical later becoming convex, aged specimens with shallow umbilicus, yellowish-greenish, fading to whitish-creamy, hygrophanous, distinctly striated at the margin, dry. Lamellae deeply decurrent, arcuate, whitish-greenish, fading to cream, brownish on dried carpophores, gill edge concolorous. Stipe 30-50 x 2-4 mm, cylindrical, equal or tapering towards the base, glabrous, dry, fragile. Context whitish. Taste and odor not distinctive. Chemical reactions on pileus unknown. Spores 7-9 x 4.5-5 µm, ellipsoid to subvirguliform, smooth, inamyloid. Basidia 35-40 x 6 µm, 4-spored. Cystidia absent. Cuticle a cutis of repent, hyaline, cylindric, not gelatinized hyphae (2-6 µm diam.). Clamp connections numerous.

Habitat

In soil under Weinmannia, Knightia, Cyathea, etc. New Zealand.

Illustrations

Notes

Macroscopically aged fruiting bodies of H. salmonipes Stev. could resemble H. involutus Stev. but the spores of the latter species are smaller and the structure of the cuticle observed in the two fungi is quite different.

SPECIMEN: NZ: T, Egmont N. P., Kaitake Range, Lucy's Gully, ZT 68/549.

Description

Pileus -25 mm, hemispherical becoming convex to plane with umbilicate centre; pale yellow-green, fading to whitish or creamy; viscid when moist, hygrophanous, distinctly striate at margin. -Lamellae deeply decurrent, arcuate; whitish to pale green, fading to pale argillaceous (brown in dried specimens), edges concolorous, entire. - Stipe 3050 x 1-2 mm, cylindrical, equal or tapering towards base, concolorous with pileus above, orange at base; dry, glabrous, fragile, solid. - Context whitish, pink or orange in base of stipe. - Odour and taste not distinctive. - Chemical reactions on pileus: unknown. Spores 7-10 x 4.5-5.5um, ellipsoid to comma-shaped. - Basidia 35-45 x 6 um, 4-spored. - Cystidia absent. - Pileipellis an ixocutis of cylindrical, repent or interwoven, hyaline hyphae (2-6 um diam.), membrane gelatinised, with plasmatic pigment; clamp connections present (Pl. 1, Fig. 7).

Distribution

DISTRIBUTION: NZ (T, W).

Habitat

ECOLOGY: Scattered; saprobic on soil among litter in mixed broadleaved forests (Weinmannia, Knightia, Cyathea). May-June.

Illustrations

ICON.: Stevenson (1962: 374); Horak (1973: 159); Taylor (1981: no. 45).

Notes

The preferred habitat of H. salmonipes (Stev.) is the anectotrophic broadleaved forests of North Island. In nature this species resembles H. involutus (Stev.) but is macroscopically separated by the greenish tinge on pileus-stipe and the conspicuously orange coloured base of the stipe (cf. H. segregatus Horak). In addition the two similar taxa are distinguished by the size and shape of the spores.
