100 SOME AUSTRALIAN FUNGI. 
Outer peridium grey, fibrous, tbe fibres agglutinated together, 
studded on the outside with particles of sand, very brittle when 
dry, and soon falling away. Inner peridium thin, yellowish, 
brittle when dry, smooth, quite free from the outer peridium. 
The centre occupied by a hard, compact nucleus, half the 
diameter of the peridium, composed of branched hyphse. 
Threads of capillitium narrower than the spores, radiating 
from the central nucleus to the wall of peridium. 
Diploderma sub erosum, Cke. Sf Mass. 
Depresso-globosum (If unc. diam.), deorsum in stipitem 
brevem attenuatum. Peridio exterio suberoso, persistente, 
ochraceo ; peridio interio nigrescente ; capillitio simplici, recto, 
radiato, hyalino. Sporis ochraceis, globosis, glabris (3-4 fi 
diam.). 
On the ground. Brisbane. 
Outer peridium externally fibroso-villose, inner peridium 
cartilaginous, blackish, almost horny when cut, but thin. Cen- 
tral nucleus smaller than in D. glaucum, at first connected with 
the peridium by the radiating, variable threads of the capil- 
litium, but soom becoming free. 
Castoreum, C. fy M. 
Peridium duplex, exterius fibrosum, deorsum in stipitem fibro- 
sam radicantem productum, interius subcartilagineum. Capillitio 
arachnoideo, nec radiato, vagi, peridio interio undique adnati ; 
floccis simplicibus, tenuibus, intertextis. 
Castoreum radicatum, Cke. Sf Mass. 
Fasciculatum, subglobosum (1-2 unc.) 2-9 in stipitem fibrosem 
coalitum. Peridio externo fusco, persistente, coriaceo ; peridio 
interno subgelatinoso, demum corneo. Capillitio tenuissimo, inter- 
texto, hyalino, sporis subochraceis, fusiformibus, inaequaliter ver- 
rucosis (12 x 5-6 /jl). 
On the ground, near St. George’s Bay, Tasmania. (G. Wintle.) 
Eaten by kangaroos and bandicoots. 
The outer peridium is leathery and tough, running downward 
and becoming confluent in a tough rooting stem. The texture of 
the outer peridium, the presence of a distinct inner peridium, more 
pronounced capillitium, paler colour, and large fusiform spores 
distinguish this from Scleroderma. 
Feziza tenacella, Phillips. 
Sessile, cupulate, then plane or convex, glabrous, umber-brown ; 
margin entire, at length repand ; flesh firm, thin ; asci cylindrical ; 
sporidia 8, elliptic, binucleate, *01 x '005-8 mm. ; paraphyses 
slender, slightly thickened at the brown curved apices. 
On the ground. Melbourne, Australia. (M. F. Reader.) 
Cups from f to J of an inch broad. The margin becomes re- 
pand, and the disc is depressed in the centre. The texture is 
toughish.
