Basidiomata up to 6 cm diam., globose to subglobose or irregularly lobed, larger sporocarps irregularly grooved and dimpled, white to pale yellow or pale pink when fresh, bruising µmkish brown, drying pale yellow brown to brown, surface glabrous, sometimes cracking to expose gleba; EtOH slowly pale µmk, FeS04 blue green, KOH pale yellow orange, Melzer's reagent negative. Gleba dark olive to olive brown, locules irregular to radially elongate, partially filled, developing schizogenous cavities up to 2 cm across. Rhizomorphs evanescent, numerous, branched, attached to indented base, concolorous with peridium. Columella dendroid, with up to 5 primary branches in longitudinal section, gelatinous, milky translucent, base traversed by strands of opaque white tissue arising from peridium. Taste nil to slightly peppery. Odour acetylenic after incubation. Peridium not separable from gleba, 575-750 µm thick, 2-layered; epicutis 75-150 µm thick, of pale brown, thin-walled, somewhat gelatinised, interwoven to subpericlinal hyphae, 1-3 µm diam., clamp connections absent; subcutis 500-600 µm thick, of hyaline, thin-walled, irregularly shaped isodiametric inflated cells, to 25-50 µm diam., clamp connections absent. Trama 150-225 µm thick, of hyaline, collapsed, loosely interwoven hyphae, 1-4 µm diam., in a gelatinised matrix, clamp connections absent. Basidia rehydrating poorly, thin-walled, hyaline, 6(-7)-spored. Spores smooth, (6-)7-9 x 3-4 µm, oblong, sometimes slightly asymmetric; apex obtuse, base with a distinct sterigmal attachment 1 x 1 µm; wall <0.5 µm thick. Utricle absent. Spore colour in KOH pale green singly, pale olive brown in mass.
New Zealand.
Habitat: hypogeous or subepigeous in Nothofagus forest, putatively mycorrhizal with Nothofagus fusca, N. menziesii, N. solandri, and N. solandri var. cliffortioides. Season: February to September.
Basidiomata usque ad 6 cm diam., globosa, subglobosa vel irregulariter lobata, alba, eburnea vel pallide persicina, contundentibus persicino-brunnea, interdum rimosa. Gleba saturate olivacea vel olivaceo-brunnea, loculis irregularibus vel radiatim elongatis. Rhizomorphae evanescentes, numerosae, parvae, peridio concolorae. Columella dendroidea, gelatina, lactitranslucens. Peridium 575-750 µm crassum; epicute 75150 µm crassa, subcute 500-600 µm crassa. Trama 150-225 µm crassa. Sporae laeves (6-)7-9 x 3-4 µm, oblongae, apice obtuso, base pedicellata, singulariter pallide virides, aggregate pallide olivaceo-brunneae. Holotypus PDD 48798.
ETYMOLOGY: From Latin ebumeus, in reference to the predominantly white colour of the fresh peridium.
REMARKS: Gallacea eburnea differs from G. dingleyae in its smaller spores and thicker peridium. G. avellana Pat. from New Caledonia resembles both these species in its white peridium, but differs in its non-olivaceous reddish gleba and smaller (5-6 x 3 µm) spores. Chu-Chou & Grace (1983) illustrate G. eburnea as "Hysterangium species 4".
