1 HIS plant, common on old rotting elm-trees, fecms 

 hitherto to have efcaped the notice of Englifli authors, 

 although it is a very confpicuous annual. I have {q.(^\\ 

 it conllant on the fame tree three or four years follow- 

 ing. It commonly begins to grow in September, and 

 continues till December or later, when each becomes 

 frequently two or three feet in circumference. Authors 

 feem to have noticed the varieties, without identifying 

 or thoroughly knowing the fpecies. I am inclined to 

 tliink Schxtfer's

an early ftate and dr)^ feafon I have feen them refemblc 

 Schxffer's K.fquamofus., tab. 29 and 30 ; yet I think they 

 are diftindl. 



It varies much from its fituation on the tree. If on 

 a Hat furface in the hollow, it commonly grows upright 

 with the ftipes central, and in a young ftate often re- 

 fcmbles white coral. When more advanced, and from 

 the fulcs, the piL'us is fpreading and undulating like an 

 efcallop fliell. Sometimes it grows downwards witl\ a 

 ftipes 5 or 6inches long,or protrudes to the outer furface 

 in an horizontal diretftion; when quite external, the 

 ftipes is often nearly lateral or almoft fellile. Ihis fungus 

 is either white with a mealy furface, or gre\'iih, Sec. 1 

 havefccn it accidentally refemblc l>ulliard's//;'. fal/. 510, 

 with red and brown fpots. I fufpect Agaricus li^Jli- 

 laius, tab. 513. fig. i. ot the lame author to be a varietv 

 alfo.
