Description

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.

Habitat

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

Illustrations

Notes

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.

Hygrophorus chromolimoneus G. Stev. 1963 [1962]

Description

Pileus 0.5-1.5 cm- diam., lemon chrome, striate at edge, very slimy, hemispherical to umbilicate; flesh pale yellow. Gills decurrent, yellow, moderately distant, thick. Stipe 2-4 cm, X 2-4 mm., bright yellow, very slimy, solid or slightly hollow at base. Spores 9-11 X 5-6 µm, oblong, hyaline, Basidia 30-35 X 5-6 µm, four-spored.

Habitat

habitat: On mossy banks, Wellington, 12.6.1949, Stevenson; Rotoiti, 16.5.1956, E. Kidson, Otari, 7.6.1958, Stevenson.

Latin

Pileus 0.5-1.5 cm. diam., chromolimoneus, ad marginem striatus, eximie, viscidus, ex hemisphaerico umbilicatus; came luteola. Lamellae decurrentes luteae, modice distantes, crassae. Stipes 2-4 cm. X 2-4 mm., vivide luteus, viscidus, solidus vel basi vix cavus. Sporae 9-11 X 5-6 µm., oblongae, hyalinae.

Notes

In general appearance this species resembles H. vitellinus Fr. sensu Bresadola, but the spores are quite different. It is close to H. citrina var. glutinipes Lange, but has larger spores and lacks orange colour.
