Description: Pileus -7 mm, hemispheric or convex when young, centre becoming depressed or subumbilicate with age; pale orange-red or deep brick-red; dry, membranaceous, coarsely innate-fibrillose (reminds of Crinipellis sp.), margin not striate, not hygrophanous. Lamellae (L 6-8,-1), rather distant, broadly adnate to decurrent arcuate in old specimens, sometimes ventricose; concolorous with pileus, edge not fimbriate. Stipe-12 x-1 mm, cylindric, equal or tapering downwards, central; concolorous with pileus; apex pruinose, appressed fibrillose towards base, dry, tough, solid, single in groups. Context orange to brick red, tough. Odour and taste not distinctive. Chemical reactions on pileus: KOH-yellow. Spore print white.
Spores 3.6-4.6 x 2.5-3 µm, ovate, smooth, hyaline, indistinctly amyloid (dextrinoid in young spores). Basidia 16-25 x 5 µm, 4-spored. Cheilo- and pleurocystidia none. Caulocystidia 15-25 x 6 µm, club-shaped, membrane thin-walled, encrusted with conspicuous yellow (KOH) pigment. Cuticle a cutis of repent, cylindric, bundled hyphae (4 -10 µm diam.), membranes thin-walled, not gelatinised, encrusted with yellow to orange pigment (KOH). Clamp connections on septa.
Habitat: On rotting trunk of Cyathea sp.-New Zealand.
Notes: A number of characters are distinctive for this species: brick red colour of the carpophores, lack of cheilocystidia and habitat on rotting trunk of ferns.
