Basidiomata up to 3 cm diam., subglobose to irregularly lobed with an indented base, white when fresh, bruising brown, mottled yellowish brown, white to brown when dry, surface with a fine pubescence which is easily rubbed off on handling, sometimes with adhering soil particles; EtOH mid brown. Gleba brownish grey when fresh drying to greyish olive to olive; locules irregular to elongate, more or less radially arranged, empty. Rhizomorph single, becoming branched several millimetres from point of attachment, up to 0.5 mm diam., attached at base, concolorous with peridium. Columella dendroid, with up to 6 primary branches in longitudinal section, gelatinous, translucent to opaque near base, stout, arising from a sterile base, nearly black when dry. Taste slightly peppery. Odour musty to faintly acidic. Peridium peeling readily in large flakes, up to 800 µm thick, 3-layered; epicutis 80-300 dim thick, of hyaline, thin-walled, compactly interwoven, bead-like hyphae, which are elongate to subglobose, 2-5(-8) µm diam., associated with droplets of oil which become minute crystalline incrustations on storage, clamp connections absent; mesocutis 200-400 µm thick, of hyaline, thin-walled, compact, irregularly inflated, subglobose to polyhedral hyphae up to 20 µm diam., clamp connections absent; subcutis 60-80(-100) µm thick, of golden brown isodiametric cells which collapse and then appear as more or less periclinal hyphae, clamp connections absent. Trama 100-300 µm thick, of hyaline, compactly interwoven hyphae, 1-2 µm diam., in a gelatinised matrix, clamp connections absent. Basidia hyaline, cylindric with narrowed base, 35-55 x 9-10 µm long, 4-6-spored. Spores minutely verrucose (by light microscopy), 12-17 x 5-6 µm, broadly ellipsoid, apex obtuse, base with a short sterigmal attachment; wall c. 0.5 µm thick. Utricle distinct, 1 µm thick, wrinkled, usually adhering to spore wall. Spore colour in KOH pale green singly, greenish brown in mass.
New Zealand.
Habitat: hypogeous to partially epigeous in modified forest, putatively mycorrhizal with Leptospermum scoparium and L. ericoides. Season: April through October.
Basidiomata usque ad 3 cm diam., subglobosa vel irregulariter lobata, basi indentata, alba, avellanea-columbrina, contundentibus brunneolis, minute pubescenti. Gleba bruneolo-grisea vel griseoolivacea vel olivaeaa; loculis irregularibus vel elongatis, plus minusve radiantibus. Rhizomorpha singularis, usque ad 0.5 mm diam., peridio concolor. Columella dendroidea, crassa, in sicco nigrescens. Peridium in squamis grandibus, paulatim deponens, usque ad 800 µm crassum; epicute 80-300 µm crassa, hyphis hyalinis, compactis, moniliformibus, 2-5(-8) µm diam., crystallis minutis incrustata, fibulae destitutae; mesocute 200-400 µm crassa, hyphis subglobosis vel polyhedricis, inflatis, usque ad 20 µm diam.; subcute 60-80(-100) µm crassa, cellulis collapsis, brunneolis. Trama 100-300 µm crassa. Sporae minute verrucosae, 12-17 x 5-6 µm, late ellipsoideae, apice acuminato; paries plus mnusve 0.5 µm crassus; utriculus distinctus, 1 µm crassus, rugosus, plerumque ad parietem sporae adhaerens; sporae singulariter pallide virides, aggregate olivaeae. Holotypus PDD 4605.
ETYMOLOGY: From Latin ruga, wrinkle, and spora, spore, referring to the wrinkled utricle surrounding the spores.
REMARKS: Hysterangium rugisporum differs from H. youngii in its smaller spores, and from H. neotunicatum in its regularly verrucose spores, and brown reaction with EtOH and to bruising.
TYPE: NEW ZEALAND, COROMANDEL, Little Barrier Island, J.M. Dingley, 9 Oct 1945 (holotype PDD 4605; isotypes DAOM 116179, OSC).
