ON GEASTER ORIENTALIS, NOV. SPEC. 
109 
this tube remains in the shape of a ring at the base of tlie interior 
peridiuni ; the smaller, in the shape of a vagina at the base of the 
peduncle, like in G. Bryantii. The exterior peridium is parch- 
inent-like ; it splits into 5 or 6, semi-lanceolate, acuminate lobes, 
bordered with a membrane, and it recurves semi-globularly. It 
very rarely splits irregularly as in Fig. 12. The upper (interior) 
surface is at first of a dirty brown- grey, like G. rufescens^ ulti- 
mately of a bright chesnut-brown colour. The capillitium and the 
spores are dark brown, like G. Rabenhorstii. The spores are verru- 
cose, and only 0-004 mm. in thickness. 
From G. Bryantii it is distinguished by its large beak, its long 
peduncle of yellowish-white, and its parchment-like peridium ; 
from G. limbatus by its double tube of the peduncle and the 
remanance thereof, and the grooves of the inner peridium above the 
ring.
