Spore-dispersal among Fungi. 



In the American JVattiralist a year or so ago attention was 

 called to the peculiar manner in which certain species of 

 Agancus disperse their spores. The spores do not simply 

 fall from the lamellae but are in some way distributed from 

 the plant, projected in all directions for a considerable 

 distance. This was first noticed in the case of Agaricus 

 illudens^ but has since been observed in connection with 

 many other species, A. sapidiis, A. adiposus, etc. One species 

 which I am disposed to consider new, very csespitose and 

 in consequence having the pilei much overlapping and, so to
