SuMSTiNE : North American Hyphomycetes

Under this genus three species are enumerated: M. capitata, 
divaricata, ramosa. It is impossible to tell definitely what species 
Hill had before him. 
The next general reference to this genus is given by Wiggers.® 
Two species are listed: M. crustacea = Mucor crustaceiis Linn, 
and M. Aspergillus = Miic or Aspergillus Scop. 
Roth^® accepts the genus, cites Wiggers and enumerates M. 
Crustacea, cespitosa, aspergillus, nidulans. 
Persoon” gives M. aurea, cespitosa aurea = Aspergillus Mich. 
2. He also adds the following species: M. rosea, glauca, Candida, 
racemosa, simplex. In a later work^® the same species are 
enumerated. 
From these references it seems clear that the genus Monilia is 
congeneric with Aspergillus and Penicillium and should be re- 
tained in that group. 
The other genera in this tribe will be discussed at more length 
in the following pages. No attempt is made to give all the prob- 
able synonyms. It was deemed advisable to divide some of the 
genera and make new genera in order to bring together the more 
closely related species. 
Many of the types of this group are not available for study and 
in a number of cases are no longer in existence. The study of 
the species of this group must necessarily be based on descriptions.
