Descriptions
Clavaria cupreicolor R.H. Petersen 1988
North Island: Auckland, Mill Bay, 29.vi.81, coll. EH, no. 43696 (holotype, PDD; isotype, TENN).
Fruit bodies up to 60 x 3 mm, simple clubs occurring singly or scattered, fusiform to cylindrical. Club of a worn copper colour ("cacao-brown"), appearing opaque-waxy, equal; apex rounded. Stipe minutely silky, with transverse reflective patterns appearing as stripes, some more orange-brown than the club ("hazel"), inserted nakedly into substrate. Taste and odour negligible.
Tramal hyphae of club hardly inflated, thin-walled, parallel, clampless, adherent; secondary septa rare. Subhymenium well-developed, pseudoparenchymatous. Basidia (Fig. 21) narrowly clavate, prominently clamped, 4-sterigmate; contents homogeneous when young, multiguttulate when mature. Hymenium agglutinated when dry.
Spores 6.5-7.2 x 6.1-6.5 µm (E = 1.06-1.18; Em = 1.12; Lm= 7.04 µm), subglobose, thin-walled, smooth; contents minutely multiguttulate to opalescent when mature; hilar appendix abrupt, papillate-truncate.

Receptacula ad 60 x 3 mm, simplicia, gregaria, fusiformia vel cylindrica, hinnulea vel copra. Hyphis efibulatis; basidiis fibulatis. Sporis ut in oratione infra, laevibus.
Basidial clamps in this taxon are extraordinarily obvious and prominent. They are exactly as reported previously (Petersen 1979) for Clavaria luteostirpata and their presence extends to the second or third subhymenial septum below the basidium when observable.
Agglutination of hymenium and adherence of tramal hyphae are especially well shown in this species. Mature basidia can be seen to have slime clinging to their apices and the bases of sterigmata as though the hymenium had been covered by such a thin layer. It is remarkable that the basidial clamp should be so easily observed in an agglutinated hymenium.
Spores seem to be standard for this complex of taxa, but apparently the guttules never coalesce to form a single large guttule which usually marks mature spores in other taxa.
As usual, fruit body colour is an easily recognisable character, but tissue agglutination and prominent basidial clamps are good supporting features.
