The Pyrenomycetese or Black Fungi belong to the division Tele- 

 omycetae of Saccardo. They are also called perfect or higher fungi, in 

 contradistinction to the metagenetic or imperfect fungi, whose relation- 

 ship to the higher fungi is in some instances known, but for the most 

 ■' part remains unknown. By means of culture and inoculation experi- 



W ments, this relationship has been more thoroughly worked out by 



It; mycologists among the Uredineae or Rust Fungi, and there is a press- 



f: ing need and an opening field of work in tracing the form relatives of 



the Black Fungi. Often the presence of deuteromycetous forms in 

 association with the pyrenomycetous has led to the assumption that 

 they are in some manner connected. While the life history of some 

 black fungi, from secondary to perfect forms, has been traced, the 

 demand of the present is for less assumption and more direct experi- 

 ments by the scientific method. 



The pyrenomycetes are parasitic or saprophytic. The parasitic 

 forms belonging to the mildews have often been treated by themselves 

 in local floras of parasitic fungi, as, for instance, by Prof. T. J. Burrill 

 in Parasitic Fungi of Illinois, and Dr. J. J. Davis, in his Parasitic 

 Fungi of Wisconsin. JLess attention has been given in local lists to 

 the more numerous saprophytic pyrenomycetes. The present enum- 

 eration embraces both parasitic and saprophytic forms. 



There may be many roads into the field of pyrenomycetology, 



♦Editorial Note.— The present paper is the fourth of a series by Dr. Fairman on the cellular 

 crvptogams of our region, the three previously published being entitled " Fungi of Western 

 New York" (Vol. I, op. 44-54 of these Proceedings), " Hvmenoniycetea; of Orleans County " 

 (Volume II, pages 154-167). and " Puff Balls, Slime Moulds and Cup Fungi of Orleans County" 

 (Proc, Vol. Ill, pp^ 206-220). The numbering of the species is consecutive throughout these 

 articles.
