576 DECADES OF FUNGI. 
198. Geaster tenuipes, n. s.; peridio exteriore 2:5 multifido 
réflexo; interiore longe pedicellato ovato subtus leviter plicato ; 
ore prominente conico plicato suleato. Gunn. No. 1778. 
Has. On the ground. 
Outer peridium thin, reflected, split to the middle into about 
eight lobes, marked with a circular pale disc, traces of which are 
visible even after the inner coat has entirely vanished ; inner 
peridium half an inch in diameter, obovate, slightly plicate at the 
base, immarginate; peduncle two lines long, incrassated above, 
slender in the middle; aperture conical, prominent, with a slight 
depression round the base. 
Nearly allied to the small form of Geaster striatus, but differ- 
ing in its far longer peduncle, and slightly plicate base. The 
folds proceed from a circular dise formed by the apex of the 
stem. 
199. Cyttaria Gunnii, Berk. ; receptaculo globoso-pyriformi 
demum cavo; basi attenuatâ nec stipitiformi nec scabrà; cupulis 
parvis. (Tas. XX. XXI.) Berk. in Hook. Antarct. Fl. vol. 2, 
p.493. Gunn, no. 1375. 
Has. On living branches of Fagus Cunninghamii. Oct. 
Growing gregariously on knobs of greater or less size in pro- 
portion to the branches on which they occur, at first pyriform, 
simply attenuated below without any distinct stem or scabrous - 
coat; at length more or less globose and hollow, 1-2 inches in 
diameter more or less soft and flaccid when dry ; cups numerous, 
with broad, irregular orifices. Asci rather short, cylindrical ; 
sporidia, eight in each MODA, broadly elliptical. Hymenium soon 
obliterated. 
This species was characterized in the Antarctic Flora ; and I 
have nothing to add to the analysis there given, except the 
perfect sporidia. I am glad, however, of the opportunity of 
figuring so interesting a species from a very complete series of 
specimens.
