Badhamia, 319 



Badhamia varia, Mass. 



Sporangia more or less aggregated, sessile or stipitate, globose 

 or obovate, grey and opaque, or shining with metallic tints; 

 stem when present generally weak and decumbent, several often 

 more or less grown together, pale yellow or reddish, springing 

 from a well developed hypothallus of the same colour; capil- 

 litium variable, well developed, knots large or not very evident ; 

 spores in clusters or free from the first, globose, minutely warted 

 all over, dingy lilac-brown, 9 12 p diameter.

The examination of a large series of the three species given 

 as synonyms above, shows every shade of transition from one 

 to another. When sessile the sporangia are globose or irregular 

 from mutual pressure; when stipitate, usually more or less 

 obovate or irregular. The amount of lime present on the wall 

 varies considerably ; when abundant, the surface is usually grey 

 and opaque ; when scanty, iridescent. The clustered stems are 

 usually very slender and decumbent, and the clusters of spor- 

 angia are sometimes pendulous. The capillitium is snow-white. 

 The distinctive features of the species as defined above are the 

 globose spores warted all over, and the smooth wall of the
