Article: Petersen, R.H. (1988). The clavarioid fungi of New Zealand. New Zealand Department of Scientific and Industrial Research, Bulletin 236: 170 pp. Wellington:.
Description: Fruit bodies up to 8 cm high, up to 4 mm thick, simple, solitary to gregarious. Stipe up to 2.5
mm thick, equal, silky, clearly different in texture and width from club, with small pale grey
subicular mat, neutral grey ("dark mouse grey") to bluish grey ("dark Quaker-drab"). Club
terete, solid, neutral flat grey ("smoke grey", "light greyish olive", "mouse-grey"); club trama
concolourous with stipe, stuffed. Taste and odour none.
Tramal hyphae without clamp connections, hyaline, thin-walled, parallel, tightly packed, of
two width ranges: (i) up to 18.5 µm diam., of barrel-shaped cells, and (ii) 2.6-3.4 µm diam.;
secondary septa absent. Subhymenium extensive, pseudoparenchymatous. Basidia 70-80 x 8-12 µm, clavate, with clamp connections; contents
multiguttulate, the guttules refringent under phase contrast; clamp connection usually very long, loop-like, appearing as a
bifurcation of the basidium base; sterigmata 4, divergent.
Spores 6.7-8.1 x 5.2-6.3 µm (E =1.19-1.50; Em = 1.30; Lm = 7.51 µm), very broadly ellipsoid,
flattened some what adaxially, smooth, thin-walled, hyaline under bright field; contents
multiguttulate, the guttules refringent under phase contrast; hilar appendix papillate, up to I
µm long.
Habitat: On humus under tree ferns.
Notes: The New Zealand material conformed in every aspect with the Australian material described
earlier.
