Lycoperdon 



apical stoma ; the whole of the upper portion being sometimes 

 evanescent. Sterile base usually stem-like. (Fig. 131.) 



The species are remarkable for their variability in size, very 

 small mature examples of all the species being frequent. They are 

 popularly named " Puff-balls " and " Devil's snuff-boxes." 



Fig. 131. — A, B, Lycoperdon echinatum Pers., young plant entire and mature plant in section. 

 One-half natural size, c, spores. X 750. d, e, L. pyriforme Schaeff., entire and in section. 

 One-half natural size, f, spores and threads of capillitium. X 750. G, section through cortex 

 of L. gemmatum Batsch X 5 ; h, outer scurfy coat; J, inner coat; K, thin membrane over 

 gleba ; l, gleba. 



Some of the species are dangerous if eaten in a raw state ; rapid 

 inflammation of the throat and a greatly swollen tongue have been 

 known to ensue. This is probably also true of species of Bovista.
