 branchlet, with spermogones, x30. c. Sterile brancblets, X30. d. Trans- 

 verse section of thallus, and d', longitudinal section of tballus, X 200. c. Four 

 syngoniniia, x350. f. Section of tballine receptacle of three apothecia, x30. 

 g. Two thecae, X 350. h. Five spores, X 500. i. Sterlgmata and spermatia,

Apothecia solitary or aggregate, paraphyses none ; spores simple 

 or 1-3-septate ; hymenial gelatine scarcely tinged with iodine. 

 Spermogones with long sterigmata and shortly cylindrical spermatia. 



This differs from the following genus in the generally dioecious 

 thallus, and more especiaUy in the absence of paraphyses and in the septate 

 spores. The apothecia in both genera have the " p^Tenium " (/. e. the 

 '* perithecium," in its former but erroneous acceptation, vide Nyl. Flora, 

 1875, p. 102) either colourless or slightly dark. In both also the sper- 

 mogones have the appearance of young apothecia.
