68 CRYPTOGAMIA ANTARCTICA. [Auckland and 
which that author regarded as a species of Asperococcus, may be identical with the present, it being very abundant 
throughout the Antarctic Islands, even so far as 64° south, where it inhabits the Icy Sea. 
Prare LXIX. Fig. 1L.—1, a portion of the frond, in an old state, exhibiting a depression from which the fila- 
ments are given off; 2, 3, and 4, spores which cover the whole surface of the frond; 5, full formed spore :—all 
highly magnified.

Has. Lord Auckland's group; on rocks left by the tide, very abundant. 
Radix magna, filis brunneis ramosis intricatis vel stupa obtecta. Caulis 3-4 unc. longus, 1 lin. diam. sub- 
dichotome in ramos paucos divisus, totus densissime ramulis quadrifariis abbreviatis pinnulatis vestitus. Rami apice 
flabellatim fastigiati; minores graciles, erecti, simplices, ramulis dimorphis quadrifariis obsiti, aliis abbreviatis 
subappressis simplicibus subulatis, alteris elongatis dichotome pinnatis, pinnulis alterne furcatis vel sub-bipinnatis, 
pinnis pinnulisque elongatis remotis. Apices nunc acuti, nune sphacelati, massam sporarum includentes. Color 
olivaceus. Substantia rigida, dura. 
Nearly allied to 5. scoparia, Lyngb.
