Gigasperma crypticum E. Horak 1971
HOLOTYPE: PDD 27002 (Isotype Herb. HK. ZT 68/504): "In humus between roots of Nothofagus fusca and N. menziesii; track to St. Arnaud Range, Lake Rotoiti, Prov. Nelson, N.Z.-, leg. Horak, 23.V.1968".
Pileus 5-25 mm diam., pyriform or irregularly tuberiform, subglobose: whitish or cream coloured, later becoming clay-brownish; dry, glabrous sometimes covered by fragile white rhizoids, not areolate; margin of pileus always attached to the stipe and never exposing the gleba. Glebe of round or elliptical cells (up to 3mm diam.), irregularly distributed rust brown; tramal plates not gelatinised. Stipe always developed and visible, conical, solid, confluent with the compact, sterile subgleba columella absent. Context whitish, not gelatinous. Chemical reactions or pileus: KOH—yellow-brownish. Taste acidulous. Smell like garlic.
Spores 27-36 µm diam., subglobose, usually large and with very thick (5-7 µm) membrane, yellow-brown or reddish-brown in KOH, neither amyloid nor dextrinoid, with prominent apiculus. Basidia 45-60 x 15-30 µm, 4-spored, large pear-shaped or like a sand-glass (in profile) Cystidia absent. Cuticle a cutis consisting of cylindrical, thin-walled, no gelatinised hyphae (3-6 µm diam.), encrusted with yellowish pigment, clamp connections present.
HABITAT: Buried in humus between roots of Nothofagus spp.; New Zealand.
