Description

‘Pileus 5-11 mm diam., orange, hemispherical to plano-convex, matt to velvety-fibrillose; flesh luteous. Gills decurrent, creamy yellow to creamy white, moderately distant with venose folds between, occasionally forked. Stipe 10-15 x 1-2 mm, luteous, sometimes orange above, sometimes with white fibrils at the foot, equal or slightly attenuated below, solid'. Spores 6-8 x 3-3.5 µm, ellipsoid, conspicuously constricted, smooth, inamyloid. Basidia 30-35 x 5 µm, 4-spored. Cystidia absent. Cuticle consisting of repent, slightly gelatinised hyphae (2-10 µm diam.) forming a cutis. Clamp connections present.

Habitat

In soil under scrub. New Zealand, Europe.

Notes

All micro- and macroscopic characters of the species described as H. julietae Stev. agree with H. insipida (Lange ex Lundell) which occurs in Europe on grassy places (see Lange 1940, P. 168 C). This fungus must be considered as an introduced species in New Zealand.

Spores 6-8 x 3-3.5 (-4) um, conspicuously constricted, peanut-shaped. - Basidia 25-35 x 5-6 um, 4-spored. - Cystidia absent. - Pileipellis an ixocutis of cylindrical, interwoven, gelatinised hyphae (3-6 um diam.), with yellowish (KOH) plasmatic and encrusting pigment, oleiferous hyphae present in subcutis; clamp connections present (Pl.

Distribution

DISTRIBUTION: NZ (NA, G, W).

Habitat

ECOLOGY: Common; saprobic on soil among litter in Nothofagus, Leptospermum scoparium and in broadleaved-conifer forests with tree ferns. May-July.

Notes

In an earlier paper (Horak 1973: 147) this species was erroneously proposed to be a synonym of the European H. insipida (Lange ex Lundell) which, however, is distinguished by scarlet colours both on pileus and stipe.
