and fused together into the ground and one or two centimeters 

 above it. One collection from Tripoli is shorter and stouter, with 

 thicker tips, but otherwise like the others. The Chapel Hill plants 

 were pale gray when fresh, and it is probable, since they have been 

 mistaken for C. Kimsei, that they may vary to almost white. The 

 species is nearest C. muscoides, which is very similar in spores and 

 other microscopic characters, but which is easily separated by dif- 

 ferent color and usually smaller size. Our plants are entirely dif- 

 ferent from C. cinerea and are larger and stouter than C. Kunzei 

 and with quite distinct spores. The European plants were sent 

 us by Romell (Carlberg's Park, Stockholm), who was much in- 

 terested in them and could not place them in any European 

 species. He makes a note that "as to shape not unlike CI. fas- 

 tigiata but color white. Spores globose, 7(a." We find the spores- 

 smooth, spherical with a distinct mucro and large oil drop, 6-7\j. 

 thick. All collections show the base to be scurfy as in C. mus- 

 coides, the tips of the branches (when dry) abruptly sub-translu- 

 cent and cartilaginous-looking.
