White : 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 

 a long 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 median." 



4a. Cyathia hirsuta infundibuliformis var. no v. 



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 /J. wide, 14-17// long, thick-walled, hyaline. (P/. i-f-.f. ij.) 



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 flaring trumpet-shaped, 8- 13 mm. high, 8-12 mm. 

 wide at the top, 2—4 mm. at the base, brownish-gray outside, 

 rough, shaggy, and very tough and brittle ; inner surface whitish, 

 dull, and marked with rather wide shallow striations ; mouth 

 recurved, ragged and much split, but not fimbriate ; bases of the 

 peridium contracted and in some specimens there is a thick felty
