decaying wood, from tufts of moss and also from a mold cover- 

 ing a fungus. It is very probable that our American species live 

 under similar conditions, particularly as they are most numerous 

 in the vicinity of forests or where there is an abundance of decay- 

 ing vegetable matter. The generic type is J. aurantiaca 

 Kieff.
