PYRENOCARPINEZÆ *. 
PYRENULACEAZE. 
PYRENULA NITIDA Ach. Syn. Lich. 125, 1814. On bark of Eiwotheca. 
Baie Ouémo. Riv. Ngoyé, May. “ Tree-trunks in Spermolepis forest on 
serpentine soil by river, 350 ft." 1102. Cosmopolitan. 
Doth specimens are untypical. 
ANTHRACOTHECIUM DENUDATUM, var. OCHROTROPUM (Nyl.), Müll.-Arg. Lich. 
Neo-cal. in Journ. de Bot. vii. 111, 1893. On wood. 1295 bis. S. America. 
The variety is distinguished by a yellow or reddish tinge over the 
normally white thallus. The yellow parts give a strong reaction, KHO+ 
erimson, and this suggests that the thallus may be invaded by some other 
species.  Wainio found the same lichen in Brazil, and placed it in a new 
genus, Bottaria (Trypetheliaceæ), with specific rank. As the perithecia are 
solitary, I have preferred to classify it as above. 
TRYPETHELIACEZXÆ. 
TRYPETHELIUM SPRENGELII Nyl. Exp. Syn. Pyrenoc. in Maine & Loire 
Mém. Soc. Acad. iv. 77, 1858. On bark of Fwotheca. Baie Ouémo, near

SPHÆROPHORACEZÆ. 
SPILEROPHORUS COMPRESSUS Ach. Meth. Lich. 135, 1803. 718, 1728. 
No. 718. “Abundant on trunks above 3500 ft. in cloud forest.” Frequent 
in the Southern Hemisphere. The thallus in both of the specimens is 
ochreous-white, almost as if bleached; described by Compton as * white, 
with stout white erecto-patent apothecia stalks and black apothecia.” 
GRAPHIDACE.E. 
OPEGRAPHA DIAGRAPHA Nyl. Syn. Lich. N. Caled. 57, 1868. On bark of 
unknown tree. Baie Ouémo, Nouméa. 
When moist the discs are brownish—not white as in Nylander's descrip- 
tion; but this may be the result of age. The lirellæ are very short, 
resembling those of O. Bonplandia var. abbreviata Müll.-Arg. 
* The arrangement followed is in general that of A. Zahlbruckner in Engler and Prantl's
