however, these banded-spored forms are considered as of specific 
rank, they should bear the name Stemonitis dictyspora Rost. 
The specimen before us represents the extreme limit of departure 
from typical Stemonitis fusca, the sooty-black sporangia showing 
hardly a trace of any surface net and the large, dark spores, meas- 
uring 11.5-13.5/4 diam. and being marked with a network of 
raised bands, which form a distinct border to the spore when seen 
in profile. 
“(2992) Cribraria ei.egans B. & C. ad. lign. putr. Aug: 
1855. Santee Canal, S. C. Ravenel (1044).” 
This specimen agrees perfectly with the published descriptions 
of the species. 
“(2717) Cribraria minima B. & C. Pine boards after rain. 
Julio 1849. Society Hill, S. C.” 
The label reads “ Cribraria microscopica” but the number is 
the one referred to in Grevillea 2 : 67 as the basis for the descrip- 
tion of C. minima. The specimen is typical C. minutissima Schw., 
though very scanty. 
“(1182) Cribraria microscopica B. & C. Underside of old 
shingles and on old rails of pine. July 1847. Society Hill, S. C. 
Yellow.” 
This specimen is in even worse condition than the preceding. 
The most diligent search fails to reveal a single sporangium. The 
published description applies to C. minutissima. 
“Arcyria bicolor B. & C. ad ram: deject: Cuba. C. Wright. 
B. & C. Fung : Cub : 542.” 
This is in poor condition, but is distinctly referable to the " digi- 
tata” form of Arcyria cincrea. 
“Arcyria globosa Schw. Herb. Schw.” 
Though a very scanty specimen, enough remains to show the 
distinctive features of the species. 
“ Arcyria minor Schw. Herb. Schw.” 
Miss Lister (Monog., Ed. 2, p. 242) refers this doubtfully to 
Arcyria incarnata Pers. The specimen before us shows a capil- 
litium free from the cup, and marked with a very open spiral of
