Hygrocybe julietae (G. Stev.) E. Horak 1971

Hygrophorus julietae Stevenson (28 D) = Hygrocybe julietae (Stevenson) comb. nov. (Basionym: H. julietae Stevenson, Kew Bull. 16: 377, 1962)
Holotype of Hygrocybe insipida (Lange ex Lundell): 'W of Slavsta. Upland, Upsala. Sweden; leg. H. Belin, 25.X.1953' Fungi Exsic. Succ. 2331. - Holotype of Hygrophorus julietae Stev. (K): 'Wellington Botanic Garden. nov.Z.; leg. Juliet Cone in Stevenson (697), l.VII.1949'.
‘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.
In soil under scrub. New Zealand, Europe.
Stevenson 1962: Fig. 2/3; Pl. 6/9.
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.

Hygrocybe julietae (G. Stev.) E. Horak 1971

SPECIMENS: NZ: NA, Waitakere Ranges: Spragg's Bush, ZT999, 1000; Karamatura Strearn, ZT 1026; Lucy Cranwell Track, ZT 1540. - G, Urewera N. P., Black Beech Track, ZT 872.
Pileus-30 mm, hemispherical to convex or expanded, obtusely umbonate to subcampanulate; orange, orange-yellow or brilliant yellow, red tints absent; distinctly viscid when moist, glabrous to minutely velvety-fibrillose, hygrophanous, strongly striate at margin. - Lamellae (8-) 10-20 (1 -5) decurrent to broadly emarginate-subdecurrent (with short tooth), occasionally forked; pale yellow to yellow with faint orange tint, edges concolorous, entire. - Stipe 10-50 x 1-2 (-3) mm, cylindrical, equal, or subattenuated towards base; pale yellow to yellow, sometimes with orange tint at apex, occasionally with white strigose or tomentose base; subviscid, glabrous, solid becoming fistulose, single. - Context yellow, occasionally with orange tint in pileus, whitish in base of stipe, brittle. - Odour and taste not distinctive. - Chemical reactions on pileus: KOH - negative. 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. I, Fig. 7).
DISTRIBUTION: NZ (NA, G, W).
ECOLOGY: Common; saprobic on soil among litter in Nothofagus, Leptospermum scoparium and in broadleaved-conifer forests with tree ferns. May-July.

ICON.: Stevenson (1962: 377); Horak (1973: 147).

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.
TYPE: NZ: W, Wellington, Botanic Garden, 1 vii 1949, Stevenson K 697.
Pileus 0.5-1.1 cm., diam., orange, hemispherical to planoconvex, matt to velvety-fibrillose; flesh luteous. Gills decurrent, creamy yellow to creamy white, moderately distant with venose folds between, occasionally forked. Stipe 1-1.5 X 0.1-0.2 cm., luteous, sometimes orange above, sometimes with white fibrils at the foot, equal or slightly attenuated below, solid. Spores 6 X 3µm., oblong, hyaline. Basidia 30-40 X 5-6 μm., four-spored.

habitat: in soil under scrub, Wellington Botanic Garden, 1.7.19491 Juliet Cone. 

Pileus 0.5-1.1 cm., diam., aurantiacus, ex hemisphaerico plano-convexus, impolitus vel velutino-fibrillosus; carne lutea. Lamellae decurrentes, e cremeo-luteolo albido-cremeae, subdistantes, plicis venosis immixtis, interdum furcatae. Stipes 1-1.5 X 0.1-0.2 cm., luteus, interdum sursum aurantiacus, subinde basi albo-fibrillosus, aequalis vel basi vix attenuatus, solidus. Sporae 6x3μm, oblongae, hyalinae.
Typus: Stevenson 697.
