 often somewhat ventricose, flexuous, glabrous or occasion-

 branaceous, subpersistent, white. SPORES oval-elliptical, smooth,, 

 white, 9-10x5-7 micr., nucleate. ODOR and TASTE mild. 



Caespitose. On rich soil of gardens, conservatories, etc., decay-

 The name refers to the shape of the stem which often resembles the 

 enlargement on the seed-stalk of the onion. The plants soon droop 

 and collapse in the wind. Hennings (in Engler and Prantl) says 

 this mushroom was introduced into Europe from Brazil and also 

 siiiics that at first there is a small sclerotium.
