SEPTOBASIDIUM Patouillarfi. 
(li., sepius, ciu-losed, here septate; basidium, the part bearing tlie spores.) 
‘ ‘ Receptacle dry, coriaceous-membi anous or crustaceous, effused. Trama looselv 
formed of coloured hypliae, rigid. Probasidia ovoid or spherical, with tliickened 
walls, coloured, producing a hyaline basidium, usually very fugacious, straight 
or curved, transversely septate. Spores hyaline, fusiform, cylindrical or clavate, 
curved. Lichenoid plants growing on living bark.” — Bourdot and Galzin. 
545. Septobasidium pteruloides (Montag.) Pat.? (I’teruloides, like the genus 
rterula ). — Lloyd describes and figures this species in Mycological Notes, No. (59, 
July, 1923, p. 1195, figs. 2429 an<l 24:!0. The description is ‘ ‘ black. Growing adnate 
as a thin ]>ad on the branches of L( ptospeinmim species (Myrtaceae), but covereil 
with dense hydnoid processes. ’ ‘ The species grows in association with a coccid 
which presumably is responsible for the elongated slightly swollen fissured galls, 
which underlie the fungus on the smaller blanches of Leptospermum scoparium 
Porst. et f. The Scptohanidium has not yet been traceil to the body of the coccid. 
The fungus forms patches, up to 1 x 0.5 cm. in size, composed of slender, rigid, 
rugose, black pteruloid processes, slightly branched in an upright direction, the 
apices blunt or acute, most of the processes being erect but some being adpressed 
to the branchlet to form the thin pad mentioned by Lloyd. South Australia —

HELICOBASIDIUM Pat. 
(Gr., helix, helikos, twisted; hasidiiim, a basidium.) 
'‘Receptacle membranaceous, soft, floccose ; effused, incrusting. llymenium 
smooth. Basidia cylindrical, more or less incurved, transversely 2 to 4 septate, 
with subulate, unilateral sterigmata. Spores white, oval or pear-shaped, smooth, 
producing, on germination, either sporidiola or a mycelium. Growing on humus 
or wood. ■ ■ — Rea. 
No species recorded for South Australia. 
PLATYGLOEA Schroeter. 
(Gr., platyn, broad; ploia, glue.) 
‘‘Receptacle homogeneous; waxy, gelatinous or coriaceous gelatinous; tuber- 
cular, wart-like, or consisting of spreading or erect convolute ])lates. llymenium 
smooth, unilateral or amphigenous ; basidia cylindrical, straight, palisade-like, 
transversely septate, with long sterigmata. Spores white, .oval or elliptical, 
obtuse or apiculate, straight or em ved : producing sporidiola on germination. 
Growing on dead wood.” — Rea. 
No species recorded for South Australia. 
AURICULABIA (Bull.) 
(L., auricula, the ear.) 
“Receptacle gelatinous-coriaceous, cartilaginous when dry; dimidiate or cup- 
shaped, substipitate or sessile; consisting of three layers, the upper layer thin 
and compact, very rarely glabrous, generally tomentose with thick, cylindrical, 
simple, erect or 'decuml'ient hairs, the intermediate layer consisting of thin, 
gelatinous hv])hae forming a compact tissue, and the lower layer forming the 
iiymenium. llymenium smooth, reticulate or ribbed, fully exposed from the fii’st. 
Basidia cylindrical, transversely 3-septate, with long, thin sterigmata, and form- 
ing a firm palisade-like layer. Spores white, cylindrical, oblong or subreniform, 
jiroducing sporidiola on germination. Growing on wood. ’ ’ — Rea. 
The famous Jew’s Ear fungus belongs to this genus. 
54(i. Auricularia sp. (specimens not yet identified*). — Receptacles mostly i to 
iin. (6 to IS mm.), gelatinous coriaceous, more or less cup-shaped, attached 
dorso-laterally by a somewhat contracted base, villous externally especially when 
young, externally whitish when young and when dried, becoming drab to nearly 
Fuscous (xr,vi.)' when old. llymenium near Vei'ona Brown (xxix.). Spores 
narrow, white, .“.5 to' 9.5 x 2.5 p. South Australia — On dead willow and otlier
