Clavaria roseoviolacea R.H. Petersen 1988

North Island: Auckland, Mill Bay, 29.vi.81, coll. P. Johnston, no. 43682 (holotype, PDD; isotype, TENN); WKR, vic. Forestry Headquarters, 21.vi.81, coll. RHP, no. 42493 (TENN); WKR, Ricker Track, 31.v.82, coll. RHP, no. 43595 (TENN); WR, Karamatura Stream, l.vii.81, coll. EH, no. 1029 (ZT); Auckland, Titirangi, Atkinson Park, 20.vi.65, coll. RFRM, no. 60 (PDD); WR, Cranwell Track, 26.v.65, coll. RFRM, no. 38 (PDD); Auckland, Northcote, Kauri Glen, 14.viii.81, coll. B. Segedin, no. 1890 (AKU).
Fruit bodies up to 70 x 4.5 mm, simple clubs, narrowly fusiform, cespitose in groups from 8 to 30, arising from individual or common whitish mycelial patches, fragile. Club violaceous rose ("alizarine-pink" to "deep vinaceous") to buffy pink ("grenadine-pink", "light Congo-pink"), darkening somewhat in age ("light Corinthian-red", "jasper-pink"), opaque, appearing waxy, equal or tapering slightly upward; apex rounded; flesh white, stuffed. Stipe striate-silky, paler than club ("light Congo-pink", "Chatenay-pink" to "Venetian-pink"), clearly delimited from hymenium. Taste and odour negligible.
Tramal hyphae 3-8 µm diam., hardly inflated, thin-walled, clampless, strictly parallel, adherent; secondary septa abundant. Subhymenium well-developed, pseudoparenchymatous. Hymenium thickened, agglutinated; basidia 40-50 x 9-11 µm, clavate, clamped to asymmetrically bifurcate, refringent, empty but persistent after spore discharge; sterigmata 4, up to 7 µm long, stout, subcornute.
Spores (Fig. 32) 7.9-10.8 x 6.5-7.9 µm (E = 1.19-1.33; Em = 1.27; Lm = 8.93 µm), subglobose, to broadly ellipsoid, smooth, thin-walled; contents homogeneous or with 1-2 guttules; hilar appendix papillate, broad.
Receptacula ad 70 x 4.5 mm, simplicia, caespitosa, roseo-violacea. Hyphis efibulatis; basidiis fibulatis. Sporis subglobosis vel late ellipsoideis (Em = 1.27; Lm = 9 µm), laevibus, ut in oratione infra.
In general shape and colour, this taxon resembles Clavaria rubicundula from North America, which produces fascicles of simple clubs. In C. roseo-violacea, however, fruit bodies are not truly fasciculate, but densely cespitose, and do not originate below the substrate level as do those of C. rubicundula, but from mycelial patches on the substrate surface. Finally, C. rubicundula belongs in subg. Clavaria.
Previously, I reported on the type specimen of Clavaria miltina Berk. (Petersen 1967b), to which C. roseo-violacea could be compared. Because material of that type was so poor, I decided to discard the epithet as a nomen dubium. Moreover, my observations indicated that tramal hyphae were clamped, so that taxon was removed from subg. Holocoryne, if not from Clavaria.
Fruit body colour is very suggestive of descriptions of Clavaria incarnata of the North Temperate Zone. That species concept differs from C. roseo-violacea in producing elongate spores (6-10 x 3.5-6.5 µm) and solitary to scattered fruit bodies.
