ASTEEODON Patouillaid. 
(Gr., aster, a star; odous, odontos, a tooth.) 
“Receptacle resupinate, effused, membranous flaky. Hymenophore with star- 
shaped or branched brown cystidia; liymenium covered with awl-like spines. 
Basidia 4-spored ; spores longish, almost colourless. ’ ’ — Killermann. 
No South Australian species recorded. 
RADULUM Fr. 
(L., radula, a rasp.) 
“Receptacle resupinate, effused, waxy or membranaceous waxy. Tubercles or 
spines thick, deformed, obtuse, simple or branched; irregularly scattered or con- 
fluent and tooth-like. Spores white or coloured, elliptical, subglobose or cylindric 
oblong, smooth. Cystidia none, cystidioles (sterile basidia) sometimes present. 
Growing on wood. ’ ’ — Rea. 
No South Australian species recorded. 
GRANDINIA Fr. 
(L., grando, liail.) 
‘ ‘ Receptacle resupinate, thin ; membranaceous, pelliculose or erustaceous. 
Tubercles or spines obtuse or occasionally j>ointed, entire. Spores livaline or 
faintly yellowish. Cystidia absent. Cystidioles rarely present and but little 
differentiated. ’ ’ — E. M. Wakefield. 
.195. Grandinia Clelandii Wakef. (Named after tlie finder, ,T. B. Cleland).— 
^‘Effused, thin, closely adnate, tomentose-membranaceous, tan-coloured, with 
closely-set irregular concolorous granules, edge indeterminate, pulverulent. Basidia 
clavate or urn-shaped, 40 to 50 x 8 to 9 sterigmata 4, (i g long. Spores elliptical, 
hyaline, 10 to 11 x 8 g. Hypliae hyaline, loosely interwoven, septate-nodose, 2.5 
to 4 /r in diameter, with erect branches often with the apices vesiculosely inflated. 
On bark.’’ — Wakefield. New South Wales. 
“This is a very distinct species. The colour is uniformly warm buff, and the 
texture somewhat loose, giving the plant a pulverulent or tomentose appearance 
when viewed with a lens. In section the most marked cliaracter is the abundant 
vesicular bodies in which some of the upward-growing hypliae terminate. These 
recall the vesicles of Sterevm purpureum, and like those occur only in the sub- 
hymenial tissue. Botli basiilia and spores are large for the genus. ’ ’ — Wakefield. 
19(). Grandinia australis Berk. (Syn., Hydnum pexatum Mass.) (L., australis, 
here for Australian). — “Irregularly effused, closely adnate, membranaceous, at 
first alutaceous (deep chamois) with scattered granules, finally becoming between 
raw sienna and buckthorn brown, very uniform in colour, with crowded granules. 
The yellowish jiigment is soluble in a solution of potassium hydrate with the 
production of a rich vinaeeous tint. Margin indeterminate, narrowly byssoiil at 
first, yellowish or concolorous. Hymenium cracked when dry. Basidia clavate 
or urniform, 25 x 5 g, with 4 sterigmata 2 to 5 long. Spores broadly elliptical, 
one side slightly depressed, (i to 7 (to 9) x 4 to 5 g. Cystidioles present, but 
scattered, sometimes fusiform and pointed, at other times scarcely differing from 
young basidia, proiecting little from tlie surface of tlie hymenium, about .10 to 
35 X 8 g. Basal hypliae branched, septate, with clamp-connections, 3.5 to 4 g, in 
diameter. On bark.’’ — Wakefield. New South Wales. Victoria — On Eucalyptus 
L ’Ilerit., Gippsland. Tasmania. March. 
“This species resembles Odontia Archeri in the vinaeeous colour which is pro- 
duced wlien sections are treated with potash, but differs from that species in its 
more uniform colour and the absence of vivid yellow tints in tlie subiculum, and 
microscopically in the shape of the spores and the absence of omliedded encrusted 
cystidia. ’ ’ — Wakefield. 
397. Grandinia farinacea (Pors.) Bourd. et Galz. (L., farinaceus, mealy). — 
'‘Effused, thin, floccose or softly membranaceous, at first pure white, finally 
cream-coloured, margin byssoid or indeterminate. Spines sometimes subulate, 
sometimes reduced to granules, very soft and fragile, with ]irojeoting sterile 
hypliae at the apex. Basidia (i to 12 to 21 x 3 to 5 with 2 to 4 sterigmata
