Sclerotinia. 



This genus consists exclusively of true parasites and has, therefore, 

 highly interested the phytopathologists ; Rostrup often studied the spe- 

 cies belonging to this genus, especially Sclerotinia trifoliorum, and 

 has contributed much to our knowledge of the individual species. 

 Also in sheer mycological respect, the individual species of Sclerotinia 

 are of great interest. 



The genus is to be divided into two strictly separated parts: the 

 species with chlamydospores (Monilia) and the species without Mo- 

 nilia; as has also been suggested by Woronin (95); a third division 

 set up by Woronin viz the heteroecious ones will of course be iden- 

 tical with those of the first one. 



Boudier (85) divided the genus into two subgenera: Stromatinia 

 (Pedicule naissant d'un stroma etale) and Sclerotinia (Pedicule nais- 

 sant d'un sclerote). Rehm. (IIP"") and Lindau (E. 6.P. 97^") use 

 the name of Boudier, Stromatinia in quite another way, referring to 

 it all species of Sclerotinia forming sclerotia in fruits. This is quite 

 an accidental character which does not deserve to be made the basis 

 of the division and has the effect that Sclerotinia pseudotuberosa, alni 

 and betulae which are just Eusclerotiniae are referred to Stromatinia. 



I shall state all the more common species of Stromatinia and the 

 corresponding forms of Monilia. As to some of the species, both
