Lycoperdon pyriforme Schaeff. 



Plates 49, 50 and 113 



Plants pyriform, often crowded, up to 4.5 cm. broad and 4.5 cm. high, usually 

 much smaller; color red-brown when dry or old, paler when fresh; cortex composed of 

 minute warts, spines and granules which are very persistent and rough to the touch like a 

 file; sometimes cracked into distinct areas. The apical pore is very slow to form, often 

 taking three weeks or a month to appear after full size is reached. The plants are con- 

 nected with the wood and with each other by conspicuous, pure white strands of my- 

 celium. Gleba changing through greenish yellow to deep olive-brown at maturity; 

 subgleba rather small, occupying only the constricted base, the chambers very small. 



Spores spherical, smooth, with a large oil drop, deep olive-brown when fully mature, 

 3.3-4.3/* in diameter. Capillitium branched, brownish olivaceous, main threads from 

 3.5-5.5^ in diameter, averaging about 3.7/z, tapering to the tips. 



The spores and capillitium of our plants have been compared with those of Peck's 

 collections, and were found to agree. The species is often found in immense quantities 

 on rotten logs and stumps and rarely in the ground. The entire plant is very persistent 

 and after maturing in the fall may pass the winter with little change, and be found in 

 good condition in the spring. It is edible and when found is abundant enough to be 

 of use.
