Observations by illanonline

Native forest near Maruia, South Island. On ground but could have been from base of tree. Smelled fragrant as if it would taste good, but milky white liquid from crushed flesh, with strong peppery sting when tasted. Sorry not much to go on....

Caps chestnut brown when moist drying to yellow, small tagging from 3mm to 12mm diameter. Growing on mossy soil on verge of grass in park.
Gills adnexed, subdistant. Stipe thin, tough, up to about 3cm long.

Cap hygrophanous, going from dull beige brown to a matt creamy white with slight sheen. Broadly convex to flat with slight umbo in some. Largest approx 4cm in diameter, circular to elliptical. Gills beige, adnate, crowded. Spore print faint, white or pale grey. Stipe has probably the most distinctive feature I can see. It is not fragile, is hollow and has a flattened cylindrical shape with a central groove on one side. Length generally less than diameter of cap. Growing in park grass near bed margin with wood chip mulch, but not on wood.

Cap very slimy, in native regeneration + parkland beds with woodchip mulch but growing from soil. green near top of stipe more marked in young examples. Gills green with yellow margins becoming yellow in mature examples. Spore print is white.

Mature caps flat to upturned and broadly umbonate, older caps becoming split and later some deeply fissured. Up to 8cm diameter. Spore print is brown. Gill attachment adnate to adnexed. Stipe equal, or broadening slightly towards base, up to 15cm in length. Veil remnant present.
Fruiting gregariously in large numbers on woodchip mulched bed.

Bright rusty orange spores. Mature caps orange, not light brown as some pictures show. Immature start off nut brown. In great abundance on woodchip mulch. Some caps 8cm or larger. Gill attachment decurrent

Just a guess, didn't record gills or spore print for some reason but from memory is brown. Growing on woodchip mulch with Leratiomyces Ceres and another similar LBM that lacked ring /veil remnant on stipe.

One photo shows this specimen compared to the other larger yellow Hygrocybe observed at this location and posted here. Differs in that it has some red colouring especially at the cap margin. The other main difference is that does not liquify/decay rapidly although it did not dry out well, it remained intact for many days vs 1-2 days for the yellow-only samples. Only one example but seems not viscid, does not blacken, spore print white.

Does not blacken. Liquefies/decays into a yellow sludge in 2 days from picking. Found in native Nikau palm / kohehohe forest. Uniform bright yellow colour on cap and stipe. Flesh delicate with waxy rather than viscid texture. Stipe hollow in section. No red colouring apparent.

Spore print white. On tree stump in damp coastal Nikau/Kohekohe forest. Collected second fresher sample with ring apparent. Cap slightly viscid when wet. Flesh of cap and stipe is tough. Stipe hollow.
