Holotype (PDD 27065); Isotype (Herb. HK. ZT 67/182): 'Camp Stream, Craigieburn Range., Prov. Canterbury, N.Z.; leg. Horak, 3.XI.1967'.
Gastrocarp 35-55 x 30-40 mm, globose later becoming depressed globose with strongly enrolled margin, dehiscent from upper part of the stipe at maturity, peridium 1-3 mm thick, brownish to reddish brown, densely covered with small orange brown squamules from the veil, dry, radially fibrillose. Gleba loculate, cells up to 3-4 mm diam., elliptic, in aged carpophores deshiscent from stipe-columella, the exposed gleba chambers covered with whitish fibrils of the veil, without conspicuous trama plates, rust brown. Stipe 60-100 x 10-17 mm, cylindrical, robust, not or only slightly attenuated towards the apex (columella), whitish, becoming yellowish ochraceous, dry, longitudinally fibrillose, hollow, without significant veil remnants. Context whitish. Odor and taste not distinctive. Chemical reactions on peridium: KOH, NH3 or HCl - negative.
Spores 12-15 x 8.5-10 µm, broadly elliptic to ovate, mostly axially symmetric, covered with minute warts, coarser towards the apex, ferruginous. Basidia 25-40 x 10-13 µm, 4-spored. Cystidia absent. Epicutis a cutis of cylindrical (4-8 µm diam.), thin-walled, not gelatinised hyphae, strongly encrusted with brown pigment; hyphae of subcutis 12-22 µm diam. Clamp connections present.
ground amongst mosses under Nothofagus cliffortioides. New Zealand.
Gastrocarpio 35-55 x 30-40 mm, subgloboso, marginem versus involuto, brunneolo vel dilute castaneo, squamis luteobrunneis e velo obtecto, sicco, innato-fibrilloso. Gleba lacunosa, e stipite dehiscente et demum exposita sed fibrillis veli obtecta. stipite 60-100 x 10-17 mm, cylindraceo, ex albido luteolo, sicco, fibrilloso, cavo, velo nullo Odore saporeque nullo. Sporis 12-15 x 8.5-10 µm, ovatis, minute verrucosis, ferrugineis. Basidiis 4-sporigeris. Cystidiis nullis. Epicute ex hyphis cylindraceis, haud gelatinosis et pigmento brunneo incrustatis cutem formantibus, septis fibuligeris. Ad terram in silvis nothofagineis. Novazelandia.
The characters of this species are the robust carpophores, the loculate gleba and the broad and ovate spores. Th. carneolum Hk. occurs together with Th. epiphaeum Hk. in montane Nothofagus cliffortioides forests and it may be difficult to distinguish the two taxa in the field.
Holotypus (PDD 27065) camp stream Craigieburn Range., N.Z.; leg Horak, 3.XI.1967'.
