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 35 x 20 mm, branched from the base, up to 3 mm thick at the thickest place (and therefore considered somewhat more fleshy than most taxa in the complex). Stipe up to 4.2 mm long, terete, branched almost from the base, off-white where protected, pale dull grey upward ("tilleul buff"); branches dichotomous, in 1-2 ranks, terete, "avellaneous", thickest below ultimate dichotomy; axils lunate; internodes diminishing gradually. Apices concolourous with branches, awl-shaped. Odour and taste negligible.
Macrochemical reaction: FCL = quickly black, with very little green phase.
Tramal hyphae of branches 2.5-8 µm diam., hyaline, clamped, strictly parallel, tightly packed, adherent, of relatively short cells. Subhymenium extensive, of crushed tortuous, uninflated hyphae. Hymenium thickening significantly; basidia 20-25 x 4-5 µm, cylindrical, clamped; contents minutely multiguttulate when mature; sterigmata 4, spindly, slender, erect. Spores (Figs 128,140) 4-5 x 2.9-3.6 µm (E =1.22-1.56; Em =1.38; Lm = 4.36 µm), ovate to ellipsoid, thin-walled, hyaline, roughened; contents homogeneous to uniguttulate; hilar appendix papillate; ornamentation of thickly scattered spines and prickles of variable length.
Habitat: On tree fern debris on clay bank.
Notes: COMMENTARY: The distinguishing characters of Ramariopsis avellaneo-inversa are (i) colour pattern of fruit body is the reverse of that of R. avellanea; (ii) conspicuously roughened spores; (iii) ellipsoid spores; and (iv) dramatic colour change in FCL. All but (iii) are different from those of R. avellanea, with which it would be mosr easily confused.
