A very delicate species, but, except in this greater degree of delicacy, smaller size and more 

 obtuse segments, very nearly allied to T. lucens. Smaller specimens than those here figured are 

 scarcely more than sinuated at the margin, and bear a single indusium upon each lobe ; whilst 

 larger specimens seem almost to have the character of the younger plants of T. lucens.
