 clavate, opaque at the ends, abundant, 125 /x long; stipe tapering

 decorated with reddish-brown fibrils, 4-8 cm. long, 4-8 mm. thick ; 

 veil forming an evanescent annulus.

This rather large genus is distinguished by a fleshy stipe, adnate 

 or adnexed lamellae, and the presence of an annulus, which last 

 is somewhat uncertain at times because of its evanescent char- 

 acter. Several of the species grow on manure or manured ground 

 and are widely distributed. There is considerable tropical ma- 

 terial of this genus in the herbarium of the New York Botanical 

 Garden, some of it evidently representing new species, but most 

 of it is poorly dried and without notes and it is impossible to 

 work it in this shape. Such specimens are retained only in the 

 hope that they may some day be matched up with more recent 

 specimens that have been better studied and better preserved.
