Description:Multiclavula coronilla (Martin) Petersen, Amer. Midl. Nat. 77:213,1967.
--- Clavaria coronilla Martin, Lilloa 5: 194, 1940. --- Lentaria coronilla (Martin) Corner, Ann. Bot. Mem. 1: 440,1950.
Figs 76, 77.
Fruit bodies up to 15 x 3 mm, simple clubs, narrowly clavate to clavate, watery white to cream-coloured,
arising from minute mycelial patches intricately associated with algae, drying cartilaginous, subtranslucent, yellowish, often with a minute apical white dot.
Tramal hyphae 3.5-6.5 µm diam., hyaline, clamped, thick-walled (wall up to 0.6 Fm thick), parallel. Hymenium thickening significantly; basidia (Fig. 76) 25-30 x 6-8 µm, ellipsoid when mature, with a hyphal basal stalk, clamped; contents multiguttulate; sterigmata (6)-8, short, slender, weak.
Spores (Fig. 77) 5.4-7.2 x 2.5-2.9 µm (E = 2.14-2.50; Em = 2.33; Lm = 6.12 µm), ellipsoid and flattened adaxially, or subcylindrical, hyaline, smooth, thin-walled; contents 1-several guttulate; hilar appendix gradual, inconspicuous.
COMMENTARY: This species appears to be worldwide in distribution, from the South American Andes to the southern Appalachians to New Zealand. It matches Multiclavula mucida in this regard.
The taxon is well marked by white, clavate, phycophilous fruit bodies on soil, supernumerary sterigmata, and thick-walled tramal hyphae.
