204 DECADES OF FUNGI. 
This species, like P. trechispora, Berk. and Br., resembles very 
closely P. scutellata, but differs from the former in its elliptic not glo- 
bose sporidia, from the latter in these organs being much larger and 
verrucose instead of smooth. It attains a larger size than either. 
The sporidia are properly eight in each ascus, but the number occa- 
sionally varies, being frequently six. A portion of the inner membrane 
of the ascus often separates with the spores, giving them the appear- 
ance of having two transparent, smooth, apiculate tips, with a large 
elliptic verrucose nucleus, and this separation often takes place before 
they are discharged, while in other asci the sporidia have the usual 
elliptic form.

I can see no difference between these specimens and the European 
species. The sporidia in both are oblong, with one end rather thicker, 
and have a single obscure colourless septum, which is not, however, 
always distinetly visible.

Minute, not 1 of a line high, at first pale yellow, at length opake 
white ; stem smooth, confluent with the turbinate or cyathiform cup ; 
hymenium at length quite plane or convex. Asci clavate; sporidia 
filiform, of various lengths. 
Closely resembling P. clavata, Fr., but a smaller species, and re- 
markable for the perfectly plane or convex hymenium. When mois- - 
tened, it has very much the form of Oraterium leucocephalum. 
359. P. stilboidea, n. s.; minuta fulvo-lutea glabra; stipite sub- 
. elongato, cupula hemisphærica concava margine incurvo; sporidiis fili- 
formibus. 
Has. On the main nerve on the underside of the leaves of a Pyrus.
