South Afiuca. Locality and collector unknown. 



This snuiU species is allied to M. lahyrhdlieiuHj N. E, Br,, but its fulh^- 

 developed growths that are not more or less compressed by bavino- divided 

 are usually nearly circular instead of elliptic-oblong in outline when viewed 

 from above, and the lines with which it is marked arc much few 

 crowded, and do not form such a labyrinth-like pattern, which varies nmch on 

 different growths. From TIf. signaUim^ N. E. Br. its convex top and fewer 

 markings at once distinguish it. I believe it has not yet flowei-ed in Enoland.
