n. violaceiis (Mass, et Rodw.) C'urin.^ found in Tasmania and A^ictoria, has 
not been I'ceovded for South Australia. 
Section A^I. — ^Peridiuin with a radicate strand; gleba traversed with a definite 
dendroid columella; spores elliptical, smooth, hyaline or tinted only. 
HYSTEEANGIUM AAttadini. 
(Gr., hystera, the womb; angeion, a vessel.) 
Plants subglobose, pyriform or tuberifcjrm, attached by radicate strands. 
Peridium of one or two layers, of woven or pseudoparenchymatous hyphae, 
usually partly gelatinized and sometimes separating readily from tlie gleba. 
Gleba of numerous, usually gelatinized, tramal plates, anastomosed to enclose 
numerous cavities lined by a hynienium of cylindrical basidia, bearing 2 to 8 
spores lou short sterigmata; penetrated by a definite simple or branched 
columella arising from a discoid sterile base. Spores smooth (or in a few 
eases covered with a gelatinous tunic), tinted or hyaline, elliptical or elliptic- 
fusiform. — Cunningham.

458. Hysterangium inflatum Rodw'. (L., inflatus, ])uffed up, inflated). — Plants 
subglobose lor shortly pyriform, to fin. (1.5 Cm.) diameter, reddish brown, 
drying dingy brown. Peridium 200 to 300 y thki, of two layers, the outer 
a shallow zone of woven hyphae arranged in a parallel manner, seated upon 
an inner layer of pseudoparenchyma. Gleba greenisly firm, cells elongate, 
arranged in a radial manner, filled with spores; tramal plates 15 to 50 y thick, 
of densely woven strongly gelatinized liypliae; columella branched, sterile base 
present; basidiii (i-spored. Spores elli])tic-obovate, smooth, tinted, 9 to 11 x 3.5 
to 4.5 y, covered with a gelatinous exospiore which is mucli inflated laterally 
but free from the rounded apex, base shortly pedicellate. — Cunningham. South

drying dingy ochre, attached by several scanty basal strands. I’eridium 380 
to' 450 y thick, of apparently two layers, the outer pseudoparenchymatous and 
coloured peripherally, the im'ier layer of global tissue upwards of 200 y thick. 
Gleba dark olive green or sage "green, firm and compact, cavities elongate, 
radiate, minute, partly filled with spnres; columella dendroid, arising from a 
sterile base; tramal plates 30 to 100 y thick, of gelatinized hyphae; basidia
