DASYPHLCEA TASMANICA, Hookji. et Haw. 



Gen. Char. Frond cylindrical, dendroid, membranaceo-cartilaginous, 

 coated externally with microscopic hyaline hairs, and formed of a 

 central articulated filament and two strata; the intermediate stratum 

 composed of longitudinal, branching, excurrent filaments; the cortical 

 membranaceous, of roundish-angular cells. Fructijication : 1, bi- 

 nate cj/stocarps immersed in the ramuli, containing moniliform spore- 

 threads issuing from a central placenta ; 2, zonate tetraspores in wart- 

 like nemathecia. — Dasyphlcea [Mont.), from Zaavi, hairy, and 

 <f)\oi,o<;, dark.

 verrucceformibiis evoluta. 



Dasyphlcea Tasmanica ; frond softly cartilaginous, rose-red, decompound, 

 much branched ; branches irregularly inserted, repeatedly divided, 

 narrowed towards each extremity, and beset with small setaceous ra- 

 muli ; cystocarps in the ramuli.

Descr. Root discoid. Frond 6-10 inches long, and as much in the expansion 

 of the branches, very in'egular in ramification. The principal stem is either 

 simple and percurrent or it divides into two or more leading branches, which 

 are either simple or forked. These throw off laterally, at very short inter- 

 vals, numerous secondary, very patent or horizontal branches of imequal 

 length, partly distichous, partly irregularly spiral in insertion, tapering at 

 base and apex, flexuous and subacute. In hke manner a third and fourth
