1. MONILINIA Honey, Mycologia 20: 153. 1928. 



Apothecia of variable size, occurring singly, or several de- 

 veloping from pseudosclerotia which are commonly formed 

 within fruits of the higher plants; conidial stage consisting of a 

 Monilia; asci clavate 8-spored; spores simple, hyaline or sub- 

 hyaline; paraphyses slender, often slightly enlarged above. 



Type species, Ciboria fructicola Wint. 



I am indebted to Dr. Edwin E. Honey for the following notes 

 on the genus: "All known North American species are vernal. 

 During the life-history of members of Monilinia two types of 

 stroma are developed (1) the ectostroma which is developed 

 first, and which functions in the rupture of the epidermis of the 

 host, and upon which develop the typical monilioid conidia and 

 (2) as a result of the initial levy on the food supply of the newly 

 invaded host or some other factor, a change takes place and in 

 affected fruits, under favorable environmental conditions, there 

 results the development of an entostroma, which after over- 

 wintering may give rise to apothecia. The entostroma is a
