ABSTRACT
Using autoclaved Bold´s liquid media we cultured spores and gametophyte fragments of Cryphaea jamesoni Tayl. We verified exosporeous germination in the species and the development of a caulematose branched protonemata. Development of chloronema from gametophyte fragments was not observed. C. jamesoni protonemata showed the so called .Macromitrium. type of development. C. jamesoni Tayl. reproductive strategy seems to be a great reproductive effort imput (RE) in sexual reproduction and apparently lack asexual reproduction.
