LYCOPERDINEAE. 



Peridium globose, or variously shaped, consisting of two or more 

 layers ; dehiscing by an apical aperture, or by the gradual falling away 

 of the upper peridial walls. Gleba consisting of cells lined by the 

 hymenium, finally breaking down into a powdery mass, consisting of 

 spores, and capillitium threads, attached to the endoperidial walls 

 or springing from a central columella, or entirely free with, or without, 

 a sterile base. Basidia bearing 4-8 sessile, or stipitate spores. Spores
