The description of C. radicans Ardissone, Alghe Terra d. Fuoco, suggests a small 

 G. Dozei, to which species it is referred by Hariot, Notarisia VII (1892) p. 1433. As 

 both species were described in 1888, it is härd to tell which name has priority. 



Distribution: Chiloé (first record), Fuegia, Falkl. (first record).
