560 Wilson : The identity of Mucor Mucedo 



and described and figured in 

 Mucedo L * the plant which i: 



the name of Mucor 

 by that name ; this, 



however, had never appeared in botanical literature until 1791 when 

 Tode described it as Hydrophora stcrcorea.f The Mucor Mucedo of 

 Linnaeus and the older mycologists is a black mould which grows 

 profusely upon bread, fruits and other vegetable substances, while 

 the Mucor Mucedo of Fresenius and his followers (de Bary, Zim- 

 mermann, Brefeld and the vast majority of modern mycologists) 

 is a gray mould which inhabits dung of various animals and ap- 

 pears upon vegetables substances as rarely as does the first species 



upon dung. 



The chief synonymy of the two species of moulds which have at 



various times passed under the name Mucor Mucedo L. is as 

 follows :
