34(). Irpex epitephrus Clel. {Kpitephrus, liere to show tlie probable relationship 
with Trcmetes epitephra ). — Forming numerous scattered small patches of 
irpicoid tubes, from a few mm. to rarely 2 cm. in size, dependent or extending 
downwards from little ledges and inequalities on the surface of dead stumps 
or wood, abnost entirely resupinate but occasionally showing a trace of pileus 
formation in the shape of a dark greyish-brown upper surface with difficulty 
distinguishable from the adjacent wood. Tubes irregular, irpiciform, about 
O.o mm., decurrent. Pinkish Buff to Cinnamon Buff (xxix.). Spores ? 5.5 x 
2.5 p, hyphae 4 p. diameter. Soutli Australia — National Park. ,Tune. 
ECHINODONTIUM Ellis et Ev. 
(Gr., eohinos, a hedge-hog; odous, odontos, a tooth.) 
"Receptacle as in Hydnum- or Irpex. Pileus woody. Spines with small teeth 
on the sides. ’ ’ — Killermann. 
No species recorded for Australia. 
SISTOTREMA (Pcrs.) Fr. 
(Gr., seistos, shaking; trema, a hole.) 
"Pileus fleshy, hemispherical, spathulate, effuso-reflexed or resupinate. Stem 
central, lateral or none. Tubes becoming broken up into teeth or plates, and 
anastomosing at the base. Flesh pale or coloured. Spore white; subglobose, 
oV)oval, or oblong; smooth or echinulate; basidia wdth 4-8 sterigmata. Cystidia 
none. Growing on the ground or on wood. ’ ’ — Rea. 
No species recorded for South Australia. 
?>. Tulje-like spaces formed of lamellae which anastomose. 
DAEDALEA (Pers.) Fr. 
(Gr., daidalos, curiously wrought.) 
"Pileus spongy, corky, coriaceous or woody; dimidiate, or resupinate; stipitate 
or sessile. Stem centi'al, lateral oi' none. Tubes homogeneous with the substance 
of the pileus and not forming a distinct layer, ii'regularly sinuous and more or 
less labyrinthiform, often becoming torn or toothed. Flesh white or coloured. 
Spores white; oval, pip-shaped, subglobose, elliptic-oblong or sausage-shaped; 
smooth or punctate. Cystidia present or absent. Annual or perennial. Growing 
on wood, very rarely on the ground ; sometimes imbi'icatc. ’ ’ — Rea. 
The irregularly sinuous or labyrinthiform tubes are the chief characteristic of 
the genus. The only species recorded, Daedulea hwnnis, usually appears with us 
as very deformed masses at the butts of olive trees. 
•IfT. Daedalea biennis (Bull.) Quel. (Syn., Polypom.<i rufescens Fr.) (L., 
hiennis, two years). — Forming large masses, up to (i x .'lin. (15 x 7.5 cm.) or more, 
usually mucli deformed, with patches forming pores, encrusting the soil and 
embedding small sticks and grass stems, at the bases of living trees and stumps. 
Better-formed sporophores show a somewhat depressed and irregular up})er 
surface with raised subsidiary pilei which are subvillous, pallid approaching 
Pinkish Buff (xxix.), in the centre with tints near Vinaceous Fawn (xL.), 
imperfect sporophores very rough and tubercular, sometimes near Cinnamon Buff 
(XXIX.). Hymenial surface decurrent on to an irregular contracted often broad 
stem-like attachment, near Pinkish Buff (xxix.), pore orifices 1 to 2 in 1 mm., 
irregular, often elongated radially, dissepiments lacerated, often defective, almost 
Irpex-like. Context firm and rather hard, browner than the Pinkish Buff of the 
pores, more earthy brown towards the base. An indefinite thick stem-like attach- 
ment buried in soil, etc., at the base of a stump or trunk. Sf)ores subspherical- 
elliptical, 5 to 5.5 x 3.4 to 4 p, occasionally 7.5 x 5.5 p. South Australia — At 
the bases of several living cultivated olives (Olea europaea L.), Beaumont near 
Adelaide; on rafter of an old bridge and on a buried stump, Mylor. Queensland. 
Europe. Developing after heavy rain and then surviving till destroyed by 
insects, so probably to be found during most of the year — so far collected from 
January to July.
