Basidiomata up to 2.5 cm diam., globose to subglobose, irregular or reniform, when fresh dull white to yellowish brown or greenish grey and sometimes cracked where exposed, bruising pale reddish brown to reddish brown or grey, surface somewhat glabrous; EtOH pale pink to red. Gleba olive to dark greyish olive; locules elongate, empty or partially filled, deliquescing. Rhizomorph single, stout, up to 1 mm diam., soon branched, attached to slightly indented base, concolorous with peridium. Columella dendroid, gelatinous, opaque to translucent, arising from a sterile base. Taste slightly peppery. Odour musty sweet to slightly acetylenic, becoming sweet-smelling on deliquescing. Peridium easily separable from gleba, 600-900 µm thick, 2-layered; epicutis 500-700 µm thick, of hyaline, thin-walled, irregularly inflated cells (parenchyma-like), 20-65 µm diam., smaller near outer surface, clamp connections absent; subcutis 100-200 µm thick, of hyaline, thin-walled, interwoven hyphae, 3-8 µm diam., clamp connections absent. Trama 50-70(-200) µm thick, of hyaline, compactly interwoven hyphae, 2-3 µm diam., in a gelatinised matrix, clamp connections absent. Basidia rehydrating poorly, hyaline, 6-spored. Spores smooth, 11-14 x (4-)5-6.5 µm, fusiform to broadly fusiform, apex acuminate, base with a short sterigmal attachment; wall <0.5 µm thick. Utricle distinct, laterally inflated up to 2 µm, irregularly loose or baggy. Spore colour in KOH pale green singly, green in mass.
Argentina, Australia, New Zealand.
Habitat: hypogeous to subepigeous in scrubland and modified forest, putatively mycorrhizal with Leptospermum ericoides and L. scoparium. Season: throughout the year.
Basidiomata usque ad 2.5 cm diam., globosa, subglobosa, irregularia vel reniformia, albida, avellanea vel viridi-grisea, contundentibus pallide rufa, rufa vel cinereae. Gleba cinereo-olivacea, olivacea vel obscure cinereo-olivacea; loculis elongatis. Rhizomorphae singulae, crasae, usque ad 1 mm diarn., peridio concolorae. Columella dendroidea, gelatina, opaca vel translucens. Sapor parum piperatus. Odor mucido-suavis vel acetylenicus. Peridium vivum facile separabile, 600-900 µm crassum; epicute 500-700 µm crassa, cellulis inflatis 20-65 µm diam.; subcute 100-200 µm crassa, hyphis intertextis 3-8 µm diam. Trama 50-70(-200) µm crassa. Sporae laeves, 11-14 x (4-)5-6.5 µm, fusiformes vel late fusiformes, apice acuminato; utriculus distinctus, lateraliter inflais usque ad 2 µm, irregulariter laxus; singulariter pallide virides, aggregate virides. Holotypus PDD 55923.
ETYMOLOGY: From Greek neos, new, and tunicatum, in reference to the invalidly published earlier name, which presumably referred to the tunic-like inflated utricle.
REMARKS: Hysterangium tunicatum Cunningham was published after 1935 without a Latin diagnosis, so is a nomen nudum in accordance with the Botanical Code, Article 36.1. The epithet neotunicatum is proposed to accommodate this species, which has spores similar to those of H. inflatum but with an irregularly inflated utricle; the two species differ vastly in peridial characters. Chu-Chou & Grace (1983) illustrate this species as "Hysterangium sp 5", although as their fig. 15 rather than fig. 14.
Hysterangium neotunicatum differs from H. rugisporum, which also occurs under Leptospermum, by its smooth spores, 2-layered peridium, and pink to red reaction with EtOH and bruising. The spores of H. neotunicatum are smaller than those of H. youngii.
Two collections [AUCKLAND, Waitakere Ranges, Huia Dam Track, R.E. Beever 761, 18 Jun 1988 (PDD 48321, OSC); ?locality, M. Chu-Chou, 25 May 1982 (NZFRI 3299)] placed in H. neotunicatum on the basis of peridial characters approach H. rugisporum in spore ornamentation.

Hysterangium tunicatum G. Cunn. 1938

Plants subglobose, to 2 cm. diameter, attached by a prominent basal strand, yellowish-brown to ferruginous, somewhat wrinkled when dry. Peridium 350-611 microns thick, readily separable in mature plants, of a single layer of compact pseudoparenchyma. Gleba ollivaceous, cells elongate, 2-6 mm. long, arranged radially, partially filled with spores; columella dendroid, arising from a sterile base; tramal plates 80-200 microns thick, composed of densely compacted gelatinized hyphae; basidia 6-spored. Spores fusiform, 11-14 x 5-6-5 microns, tinted yellow, apex acute, base pedicellate, covered with a conspicuous inflated exospore which is more prominent basally.
