Thallus usually dicecious, cylindrical, intricate ; within longitudinally 
cellular; gonimia chiefly towards the surface, 2-4 in each nodule. 
Ephebe pubescens Nyl.—a. Thalline branchlet, with apothecia, x30. 6. Thalline 
branchlet, with spermogones, X30. c. Sterile branchlets, x30. d. Trans- 
verse section of thallus, and d’, longitudinal section of thallus, x 200. e¢. Four 
syngonimia, x 350. f. Section of thalline receptacle of three apothecia, x 30. 
g. Two thece, X350. 4h. Five spores, X500. 7. Sterigmata 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 dicecious 
thallus, and more especially in the absence of paraphyses and in the septate 
spores. The apothecia in both genera have the “ pyrenium” (7. ¢. 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.
