A variable species in colour of sporangium and mass of spores 

 and capillitium. The distinguishing characters are the fusiform 

 elaters with long, smooth, tapering tips and flat spirals, and 

 the warted spores. Varying from 2 4 mm. high ; solitary, or 

 in more or less confluent clusters of from 2 7 on a common 

 stem, which is obviously composed of several confluent' stems, 

 and hence forming a stipitate aethalium. The elaters are 

 sometimes branched near the tips. I have examined the type 

 specimen of Trichia lateritia in the Paris Museum, and find 

 that it agrees exactly with Trichia fragilis in the structure of 

 the spores and capillitium.
