Seaver: Study of Genus Lamprospora 
11 
5. Lamprospora annulata sp. nov. 
Plants gregarious but not crowded, at first globose and partially 
immersed in the substratum becoming expanded and with the 
hymenium plane or nearly plane and more or less pitted and 
roughened, pale orange, .5 mm. to nearly 1 mm. in diameter; asci 
cylindric or subcylindric, rather abruptly attenuated below into a 
short much contorted pedicel, entire ascus about 200 /4 long and 
about 20 fx in diameter, at first almost filled with the spores, in 
older asci the lower part stretching and becoming about equal in 
length to the spore-bearing portion; spores i-seriate from the 
first, perfectly globose and smooth when young and containing 
a few small oil-drops and granules, 12-14 ■/* in diameter, with two 
small rings appearing at an early stage about the proximal and 
distal sides of the spore giving rise to four small circles where 
the rings pass about the periphery of the spore, rings increasing 
in size until they reach a thickness of about 3 4, the surface of 
the spore becoming minutely verrucose with age, the rings at 
maturity giving the spore a short cylindric appearance with the 
axis of the cylinder parallel with the ascus, entire spore when 
mature about 16-18/4 in diameter, rings of about the same 
diameter and nicely fitted over the opposite sides of the spore, 
the two rings usually parallel but occasionally one of them 
shifted out of its normal position, hyaline; paraphyses thickened 
above and densely filled with large granules, about 5 /4 in diameter 
at the widest point. 
On soil among moss and algae. 
Type locality: Portland, Connecticut. 
Distribution: New York and Connecticut. 
In addition to the type of this species which was collected in 
Portland, Connecticut, August, 1913, one collection was later 
made near New York City. This last collection consisted of 
three plants each less than one millimeter in diameter. The 
spore characters were identical with those of the Connecticut 
specimen. 
6. Lamprospora spinulosa sp. nov. 
Plants gregarious, minute, usually not exceeding 1 mm. in 
diameter and often less, at first closed and nearly globose, grad- 
ually expanding at maturity with the hymenium slightly convex 
and surrounded by an irregular fringe-like margin, externally 
slightly floccose, hymenium roughened by the asci which protrude
