BiostatusPresent in region - Indigenous. Non endemic
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 30 x 5 mm, branched, with no discernible basal pad. Stipe up to 20 x 2
mm, not slender or delicate, terete to somewhat flattened, concolourous with branches.
Branches dichotomous to irregular, terete, up to 1.5 mm thick, "pallid yellow orange" (teste
McNabb annotation); flesh concolourous; axils rounded. Apices awl-shaped, small,
denticulate, concolourous with branches.
Taste and odour not recorded.
Tramal hyphae of upper parts 2-8 µm diam., hardly inflated, clamped, free, hyaline, more or
less parallel. Subhymenium rudimentary. Hymenium thickening; basidia 55-60 x 7-8 µm,
clavate, clamped; contents minutely multiguttulate; sterigmata 4, stout, divergent.
Spores 5.0-6.1 x 5.0-5.8 µm (E = 1.00-1.13; Em =1.05; Lm = 5.65 µm), globose to
subglobose, thin-walled, smooth, hyaline; contents opalescent to uniguttulate; hilar appendix
small, papillate.
Notes: Corner (1950; p. 355) examined the type specimen of Clavaria archeri and found ellipsoid
spores, but Petersen (1978c) reported that the type specimen produced spores 5.6-6.7 x 5.2-6.0 µm (Em =
1.15; Lm = 6.32 µm). The sole fruit body of that specimen is broadly spathulate
or lobed, suggestive of the irregularly branched New Zealand representatives. Unfortunately,
only one collection (dried) has been examined from New Zealand. Berkeley described the
colour of C. archeri as orange, to which fruit bodies dry, but McNabb's note seems very
close, and his specimen is accompanied by an aquarelle.
