Hygrophorus aurantius sensu G. Stev. 1963 [1962]
Pileus 0.5-1.5 cm. diam., apricot, hemispherical to flattened, matt; flesh apricot. Gills slightly decurrent, yellow to apricot, moderately thick, moderately distant, rather shallow, occasionally forking with venose folds, between. Stipe 2-4 cm. X 2-3 mm., pale apricot, smooth to silky fibrillose, solid, rather brittle. Spores 5 X 5-6 µm. hyaline

This small apricot-coloured species with small globose spores seems fairly common in New Zealand, though it is little known in America beyond its original description from Florida. It has also been found in Japan (Imazeki & Hongo, 1957).
Hygrophorus brunneus sensu G. Stev. 1963 [1962]

Gills decurrent, forking in larger specimens, distant. Stipe 1-1.5 cm. X l-2 mm., fawn to light brown, velvety to subfibrillose, fringed with white hyphae at base, solid, rather tough. Spores 7 X 5 µm., hyaline. Basidia 30-35 X 5 µm. four-spored.
habitat: attached to moss or rooting on banks in the bush, Wellington Botanic Garden, 2.6.19491 Levin, 18.6.1949, both Stevenson.
Gleland remarks, 'This species is probably better placed under Omphalia', but, as it has Hygrophoroid basidia and gill trama it is here placed in Hygrophorus subgenera. Hygrocybe. The exact colour of the spore print needs to be determined.
Hygrophorus chromolimoneus G. Stev. 1963 [1962]

At the time of collection the spore print was noted to be white but the spores were not examined with a microscope. A later search revealed many mould spores; a very few spores, 4x5μm., ovoid, were seen attached to basidia but these may have been immature.
