Cap 10-30 mm; dry, not hygrophanous; orange-brown, centre darker red-brown to umber; finely innate-fibrillose to yellow squamulose; margin reddish-orange with fine orange-brown fibrils. Gills intensely red-orange to orange-red with a yellow edge. Stipe cylindrical; citrinous to golden-yellow, sometimes with an olive shade; darkening to grey-brown or black from base, apex paler. Veil orange-brown, later wine-brown; sparse; cortina dark yellow. Flesh dirty yellow, darkening to dirty brownish or black in stipe-base; odour faintly raphanoid; taste nil. Reactions: NaOH dark red to black in flesh, blood red on gills, wine red to dark red on cutis and stipital veil; fluorescence nil. Micro: spores obtusely elliptic, 5-6.5  3.5-4.5 µm, finely punctuate.

in Nothofagus forest, uncommon.

A small dermocyboid fungus with beautifully orange gills and a often blackening stipe. C. largofulgens, in myrtaceous copses, is similar with similar spores, but larger and viscid. The species are genetically close but distinct.

Cap 15-45 mm, dry, weakly or not hygrophanous; golden yellow, young yellow-brown which persists at the centre; finely innate fibrillose to finely granulose-squamulose, margin not striate. Gills pure yellow to citrinous. Stipe cylindrical to clavate; pale yellow with a few brownish-yellow fibres near base, apex paler. Veil dark yellow to brownish-yellow, sparse; cortina pale yellow. Flesh pure yellow; odour agaricoid to faintly raphanoid; taste nil. Reactions: NaOH blood red on cutis and gills, red to vinaceous on stipital veil, weaker red to orange in context; guayac nil; fluorescence nil. Micro: spores elliptic to amygdaloid, 8-10  4.5-5.5 µm, moderately and rather sparsely verrucose.

in Nothofagus forest, fairly common.

A beautifully golden-yellow dermocyboid fungus, considerably smaller than the more common C. canarius. Cf. Pholiota chrysmoides. C. icterinoides is similar but smaller and paler with a weaker alkaline reaction. As shown by molecular studies, the two species are closely related but distinct.

Cap 20-60 mm, viscid, hygrophanous, sometimes weakly; warmly yellow-brown with a faint orange tinge, disk darker, slightly red-brown, young with a thin yellow frost; glabrous to innate fibrillose; margin greyish yellow with a conspicuous yellow rim, not striate. Gills yellow-grey. Stipe cylindrical to clavate, dry; dirty white to yellowish with sometimes thick yellow girdles on lower part, apex white. Veil yellow, fairly copious to sparse. Flesh yellow to yellow-brown, sometimes with a red-brown tinge; odour faintly raphanoid; taste nil or slightly fetid. Reactions: NaOH strongly yellow-orange to red on cutis and stipital veil, sometimes weaker; guayac green. Micro: spores elliptic, 6.5-8.2 × 4-5 μm, rather weakly verrucose.

In Nothofagus forest, fairly common.

The species may look like a Telamonia when small or in dry conditions, has been shown by molecular markers to belong to section Icterinula, which is mostly composed of dermocyboid species. It can be recognised by a remarkable yellow rim on the cap, often paired by yellow veil girdles on the stipe. Cf. C. viscoviridis, which also presents a yellow rim, but whose stipe is glutinous.
