 from the Missouri river. The recently taken specimen is the largest 

 puff-ball so far reported in this part of the world, being 22 inches in 

 diameter. It is entirely unlike the common giant puff-ball; in color, 

 being at maturity a rich seal-brown; in its peridia, the outer breaking 

 up naturally into somewhat regular scales, an inch or more in diameter ; 

 in texture, being much more dense, the capillitium firm to the touch 

 and giving to the entire fructification a persistence that is truly re- 

 markable. In short, the last-named puff-ball is certainly the finest 

 thing of its kind, is rare and should be watched for and prized by all 

 collectors.
