WuHiTE: THe NIDULARIACEAE OF NortH AMERICA 261 
cases composed of three parts, namely, of a thick and usually 
dark colored coat, a light hyaline thickly interwoven portion 
which bears the basidia, which in their turn bear the spores. The 
center part is composed of innumerable spores mixed with branch- 
ing filaments. The walls of the spores are very thick, these 
spores having long been separated from their basidia. The funic- 
ulus is composed of three parts ; the lower portion is variable 
as to length and thickness, its lower extremity is expanded and 
attached to the peridium; the upper portion is more regular in 
shape and is attached by its upper extremity to the sporangiole ; 
it is rather swollen in the center, in which portion there is enclosed 
along and slender filet composed of innumerable hyaline, inter- 
Woven filaments, which can be drawn out if great care is used in 
_ the process and forcibly distended without breaking, according to 
Tulasne to a length of 12 cm. These two parts are joined by a 
much narrower and shorter portion to which Tulasne gives the 
name of “ filet médian.” 
4a. CYATHIA HIRSUTA infundibuliformis var. nov. 
Peridia 1.5-18 cm. high, funnel-shaped, 1-2 cm. wide at the 
top, 1.5-2 mm. at the base, 4-5 mm. in the center where the 
Peridium is contracted; outer surface of the peridium brownish, 
Coarsely shaggy-tomentose ; inner surface dull brownish, clearly 
striate, but not below the contraction ; mouth minutely fimbriated ; 
Sporangioles dull brownish, 2 mm. in diameter, flattened ; spores 
8-12 » wide, 14~1 7 » long, thick-walled, hyaline. (PV. 74. f. 75.) 
Growing singly on leaves and moss.

__ This variety differs from the type in the definite funnel-shape 
of the peridium, and in the nature of the tomentum, and to a less 
degree in the size of the spores. Further material may necessitate 
a different treatment. 
5. Cyathia dura sp. nov. 
__ Peridia flarin ‘trumpet-shaped, 8-13 mm. high, 8-12 mm. 
wide at the Sis 2-4 aii a the tec. brownish-gray outside, 
1 sh, shaggy, and very tough and brittle ; inner surface whitish, 
dull, and marked with rather wide shallow striations; mouth 
sScurved, tagged and much split, but not fimbriate ; bases of the 
Pendium Contracted and in some specimens there is a thick felty
