NIDULARIACEI. 



irregrilar fissures ; sporangia onveloped in jelly, subrotund, or disc-shaped, 

 their outline forming a broad elipse (almost a circle) with a major axis of 

 about ^ of an inch, shining, of a rich dark brown colour, sometimes hol- 

 lowed inwards on one side, but not umbilicate, and showing no trace of an 

 elastic cord such as exists in Cyafhns. Sporidia colourless, slightly varying in 

 shape, globose, pear-shaped, or elliptical, produced on sterigmata, 0"0002- 

 0003 in. across.— i^.C. (Fig. 144 J

[United States.] 



Plants at first connected by a web, at length smooth, subglobose, yellow- 

 ish ; outer peridium consisting of two substances, lined by the inner peri- 

 dium, which is quite distinct and separated by some moisture, white, pel- 

 lucid, and shining, at length both split together in a stellate manner, and 

 the inaier becomes suddenly inverted, while in general it still remains at- 

 tached by the apices of the stellate margin, and the sporangium is shot forth 

 to a considerable distance. Sporidia ^^^ in. long, elliptic or curved and 

 irregular. The rays of the outer peridium are orange within. — Eng Fl.
