276 Wuite: THE NIDULARIACEAE OF NortH AMERICA 
Nidularia Alabamensis Atk. Bull. Cornell Univ. (Science) 3 : 23- 
1897. 
Peridia subspherical, sessile, 2-10 mm. wide, 2-9 mm. high, 
reddish-brown or dirty cinnamon-colored, at first very floccose-pul- 
verulent, gradually becoming smoother with age, dehiscing irregu- 
larly or not at all; peridium thin and rather brittle, tuberculose ; 
inner surface is shiny, smooth, brownish ; sporangioles very numer- 
ous, darkish brown, barely 1 mm. in diameter, somewhat angular 
and depressed ; spores hyaline, thick-walled, 6-10 long, 4-7 # 
wide. (/7. 17. f. 10-16, 20; Fl. 18. f. 19.) 
Plants gregarious, rarely singly on wood.

The floccose pulverulent appearance of the surface of the peri- 
dium is caused by the innumerable ends of the filaments which 
compose the peridium protruding above the- main structure, soon 
becoming broken or eroded. Thisisa very characteristic feature 
which renders this species easily recognizable. 
Atkinson (/. ¢.) describes NMidularia Alabamensis, which un- 
doubtedly belongs here substantially as follows : Peridia spherical, 
sessile, reddish-brown, roughened, 4~5 mm. in diameter, irregularly 
dehiscing by the breaking into fragments of the upper portion €X- 
posing the sporangioles which completely fill it; no “ rooting ; 
threads ; sporangioles lenticular, shiny, dark or blackish-brown, 
barely 1 mm. in diameter, corrugated, hard, filled with a whitish 
pulpy material which is composed of stout irregular flexous OF 
blanched knotty strongly tuberculose threads with which the 
spores are mixed ; the spores are obovately hyaline, 4-6 x 3-4 
On decaying wood.

2. Granularia castanea (Ell. & Ev.) sp. nov. 
Nidularia castanea Ellis & Everhart in herb. 
Peridia small, elongate-globose, or subspherical, sessile, pian 
times confluent, .5—2 mm. long, 0.5-1 mm. high ; peridial Wears 
very thin, and brittle at first, pale yellowish fawn-colored, gT@°" 
ually as the plant matures becoming grayish, and somewhat tubet- 
culose from the inner pressure of the sporangioles, dehiscing 
irregularly, the outer covering often breaking away completely,
