122 THE FUNGI WHICH CAUSE PLANT DISEASE 



Nematospora Peglion (p. 121) 



Colonies (in culture) disciform; cells elongate; asci cylindric, 

 8-spored; spores filiform, continuous, long-ciliate, hyaline. 



Monotypic. 



N. coiyli Pegl.,* the cause of malformation of the hazel nut in 

 Italy, is a peculiar fungus with what appears to be asci contain- 

 ing eight long slender flagellated spores. 



Endomycetacese (p. 120) 



Mycelium usually well developed, often producing a luxuriant 

 growth, multiseptate; asci borne singly on branches, or inter- 

 calary, 4 to 8-spored; spores one-celled; conidia produced apically, 

 unicellular. 



Ket to Genera of Endomycetaces 



Mycelium poorly develop)ed, parasitic on 



Mucorales 1. Podocapsa. 



Mycelium well developed 

 Asci formed after conjugation of a pair of 



spirally entwined branches 2. Eremascus. 



Asci formed asexually, produced termi- 

 nally, rarely intercalary. 



Asci 4-spored 3. Endomyces, p. 122. 



Asci 8-spored 4. Oleina. 



Endomyces Rees 



^(ci;j5. n Mycelium well developed, byssoid; asci 



" Pva z"?^ borne singly on the ends of short lateral 



^3 branches, globose to pyriform, 4-spored, 



spores continuous. 



The members of this genus are of ques- 



M tionable importance as parasites. Some 



'^ are commonly found in sap exuding from 



F:o. 83. — Young spore x jtTi .1. ,., 



sacs of E. maU, spores ^^^^ wounds where they, together with 

 After Le'ilris.'" *^™^* °*^^^ ^^^ present, set up a fermentation 

 the products of which prevent the wound 

 from healing and result in injury. One species has been re- 

 ported in America as an active parasite on apples.
