Basidiomata 5-25 mm diam., subglobose or irregular, depressed around basal attachment, rarely with an exposed gleba. Peridial surface slightly tomentose, finely wrinkled or smooth, white to cream-coloured drying pallid ochraceous. Context thin, fragile, off-white. Gleba white to cream becoming pallid ochraceous, loculate, locules small,irregular. Stipe absent. Columella absent or present, rudimentary, percurrent. Odour when fresh pleasant, resembling dried apricots; taste not recorded. Latex absent. Peridiopellis 70-150 µm wide, a dense turf of upright to repent, hyaline hyphal tips 20-55 x 2-4.5 µm diam., becoming tangled and interwoven. Peridial context 210-450 µm wide, of tightly interwoven, non gelatinised, hyaline hyphae 2-3.5 µm diam., sphaerocysts 12-22 µm diam. in scattered nests. Endocystidia absent. Columella context when present of interwoven, hyaline hyphae 2-3 µm diam. Hymenophoral trama 40-75 µm wide,of interwoven, hyaline hyphae 2-4.5 µm diam., not gelatinised, with sphaerocysts 12-27 µm diam. in scattered nests. Subhymenium poorly developed, 11-20 µm wide, with 1-2 tiers of isodiametric cells 5-9 µm diam. Basidia 25-35 x 9-11 µm, hyaline, ventricose to clavate, mostly with 1 or rarely 2 sterigmata 3-5 x 1-2 µm, robust. Cystidia 24-49 x 8-15 µm, broadly ventricose with broadly rounded apices and few granular contents refractive in KOH; arising in subhymenium, not extending much beyond basidia, rare. Spores 9-12.5(-14) x 9-12(-14) µm (10.88 ± 0.32 x 10.09 ± 0.3), Q = 1.05-1.07, globose to subglobose, orthotropic and symmetric, wall hyaline. Ornamentation amyloid, a dense spiny reticulum of warts and spines 2-4 µm high, bases just coalescing or several joined at their bases by low lines 0.2-0.8 µm high or ridges ± 1-1.5 µm high in a partial reticulum. Hilar appendix 1-1.5 x 0.5-1 µm, cylindrical; plage inamyloid. Spore colour in mass hyaline, in the locules of the dried gleba appearing pale cream coloured.
HABITAT AND DISTRIBUTION: Hypogeous, growing in scattered groups among leaf litter in Nothofagusfusca, N. solandrii, and N. menziesii forests andLeptospermum scoparium or Kunzea ericoides scrub. Fruiting period Mar-Nov.
NOTES: Gymnomyces redolens is widely distributed in New Zealand. It differs from other New Zealand taxa in the robust spiny-reticulate ornamentation of the spores, and the mono- or bi-sterigmate basidia.The nomenclatural history of this species is given in Lebel & Castellano (2002).
HOLOTYPE: New Zealand, Auckland, Mt Te Aroha, specimens collected among debris on the forest floor adjoining tracks in rainforest at the base of Mt Te Aroha (350 ft), May 1940, G. Cunningham 10141 K (isotype PDD).
