Seaver : Study of Genus Lamprospora 
19 
Type locality: California. 
Distribution : Known only from the type locality. 
Illustration: Cooke, Mycogr. pi. hi, f. 398. 
A specimen of this species collected by Harkness in California 
has been examined. The species differs from L. Constcllatio in 
the much smaller size of the spores. The plants are also much 
smaller. 
17. Lamprospora discoidea (P. Henn. & E. Nym.) 
Barlaea discoidea P. Henn. & E. Nym. Monsunia 1 : 33. 1900. 
Barlaeina discoidea Sacc. Syll. Fung. 16: 710. 1902. 
Plants scattered or gregarious, sessile, at first subglobose, ex- 
panding leaving the margin elevated and hymenium slightly con- 
cave, but soon becoming plane and later strongly convex, minutely 
roughened by the protruding asci, entire plant reaching a maxi- 
mum of 2 mm. in diameter (usually 1 mm. in diameter at ma- 
turity), color white or grayish white or with a slight tinge of 
yellow or cream ; asci subcylindric above, tapering below into a 
slender stem-like base which is usually forked, about 200-250 
X 20 //,; spores i-seriate, smooth, with one large oil-drop which 
nearly fills the spore, rather thick-walled, 15-20 /a in diameter 
(usually about 17 /a), hyaline; paraphyses slender, slightly en- 
larged upwards, about 5 ^ in diameter at their apices. 
On rather sandy soil or among moss. 
Type locality: Java. 
Distribution: New York; also in Asia. 
The pale color is the distinguishing character of this species, 
which was found to be very common in the New York Botanical 
Garden during the past season. It is very different in appearance 
from any of the other species here described.
