form ; spores bright brown-violet (brown in the mass), very 

 delicately warted, 7 9 mk. 



Fairmount Park, Phila., Pa. and Ohio (Morgan). 



This Tilmadoche has marked characteristics. The stipe for 

 a short distance from the base is very dark, but suddenly 

 changes to a yellowish-white. When the sporangium bursts, 

 the top part of the wall generally pulls out the capillitium 

 immediately over the central lime-granule, so that the latter 

 is exposed to view. In some teases, when quite large, the 

 granule falls out, leaving a circular empty space in the centre 

 of the sporangium, without disturbing the outline of the capil- 

 litium. The capillitium is very flimsy, and its faint bluish tint 

 in the mass quite marked under a parabolic reflector. The 

 metallic lustre of the sporangium wall is constant in the speci- 

 mens collected during different summers. (Wing.)

The filmy reticulate mycelium at length disappears, and the 

 peridia are scattered, looking at first sight from their white 

 stems like Diacliaea. The species is altogether distinct from 

 T. lateritia, Lev. The dust of the peridia consists of irregular 

 fragments of a bright orange-red.
