of both forms the sporangium wall is hexagonally reticulated, 

 but this is not a constant feature ; it occurs in specimens 

 collected in tlie field, as well as in those grown in the laboratory.

 gium wall ; when mounted it is pale brown ; it consists of 

 irregular branching threads, 4 /i diameter, inflated here and 

 there, rough with minute warts and scattered, blunt spines. 

 The spores, in mass, are paler than the capiUitium ; when 

 Qiounted they are brownish, 15 to 17 fi diameter, spinulose 

 with close set spines, which appear to form a border about 1 /u 

 wide when the profile of the spore is focussed.
