Previously named by me (Trans. Lin. Soc. 1890) Stirjo- 

 nema ephebioides, Wilson, from a few small imperfectly 

 developed specimens. The lenticular con-colorous bodies 

 then noted by me as apparently connected with the plant, 

 were possibly foreign to it.

 bluish ; apothecia terminal in sub-globose open thalline 

 receptacles. Spermatia oblong. Spores 8, colourless, ellijj-
