Clavaria plumbeoargillacea R.H. Petersen 1988

North Island: Auckland, Mill Bay, 6.vii.81, coll. RHP, EH, no. 1064 (holotype, ZT; isotypes, PDD, TENN); WR, Walker's Bush, 30.vi.65, coll. Dingley, RFRM, no. 77 (PDD).
Fruit bodies up to 80 x 4 mm, simple clubs, solitary to gregarious but not cespitose or fasciculate, "at first grey, pale blue-grey, turning to pale argillaceous with age" (teste Horak annotation). Stipe rounded at base, with no basal mycelial pad, terete, appearing silky, up to 30 x 3 mm, clearly distinguishable from club. Club terete to longitudinally wrinkled or sulcate, appearing waxy; apex rounded.
Tramal hyphae of club 3-12 µm diam., inflated, clampless, thin-walled, hyaline, free, parallel. Subhymenium extensive, pseudoparenchymatous. Hymenium thickening; basidia 90-105 x 13-15 µm, clavate, with a long, equal stalk portion and abruptly flaring apex, asymmetrically bifurcate to clamped; contents obscurely refringent when mature to granular; sterigmata 4, up to 10 µm long, curved-ascending to curved-divergent.
Spores (Fig. 29) 8.3-10.4 x 7.9-9.7 µm (E = 1.00-1.16; Em = 1.09; Lm = 9.58 µm), globose to subglobose, thin-walled, smooth; contents uniguttulate when mature; hilar appendix short, broad, papillate.
Receptacula ad 80 x 4 mm, simplicia, solitaria vel gregaria, juniora caesia, vetustiora argillacea. Hyphis efibulatis; basidiis fibulatis. Sporis globosis vel subglobosis, laevibus, ut in oratione infra.
Again, I have only two specimens, but also a good photograph, colour sketch, and notes. Superficially, fruit bodies must resemble those of some Cordyceps, being very terete and straight. Colours are, of course, reminiscent of Clavaria muscula (smaller spores, no argillaceous shades) and C. ardosiaca (higher P" value, no argillaceous shades, and usually fasciculate fruit bodies).
