Collections Examined

Holotype (PDD 27066); Isotype (Herb. HK. ZT 67/151): 'Atkinson Park, Titirangi Range., Auckland, N.Z.; leg. McNabb & Horak, 8.X.1967'. - The following collections deposited at PDD are conspecific: PDD 6230, 26010, 26011, 26012, 26013, and 26015.

Description

Gastrocarp 10-20 mm diam., globose or ovoid, subhypogaeous buried among litter, peridium deep orange, golden yellow or reddish brown, mucilaginous, very glutinous, cuticle cartilaginous, up to 2 mm diam., margin of peridium not dehiscent from the base of the stipe, veil remnants absent. Gleba loculate, cells 1-2 mm diam., not radially arranged, without branching tramal plates, rust brown, neither exposed nor dehiscent from stipe (columella).
Stipe -15 x -3(5) mm, turbinate or bulbous-marginate at the base, strongly tapering towards the apex or absent, columella not branched, merging into central parts of peridium. Context whitish, tough. Odor and taste nor distinctive. Chemical reactions on peridium: KOH - negative.
Spores 13-15 x 7-9 µm, elliptic, verrucose, warts tubular and coarser towards the apex, perisporium well developed, ferruginous. Basidia 30-45 x 9-12 µm, 4 spored. Cystidia absent. Epicutis consisting of highly gelatinised, cylindric (2-7 µm diam.), thin-walled hyphae, encrusted with brown pigment; subcutis cellular. Clamp connections present.

Habitat

In soil amongst litter, under Leptospermum scoparium, Knightia sp., Cyathea sp., etc. New Zealand.

Notes

New Zealand a closely related form of this species is known to grow under Nothofagus (N. fusca, N. menziesii). This variety is distinguished from the type by its slightly larger spores, more gelatinous peridium and in many cases the beech forest inhabiting species does not have a well developed stipe and the columella is often absent or rather oblique (see Herb. HK. ZT 67/159; 68/635).
