Entomogenous Fungi

Host: Diabrotica sp. (adult) Trinidad. 



The above description is based upon a specimen from Trinidad, 

 British West Indies, which is believed to be identical with the 

 form described by Patouillard. The measurements of the spores 

 (8X6 microns) as given by this author, apparently included the 

 gelatinous substance surrounding the spores. 



2. Hirsutella saussurei (Cooke) comb. nov. 



Isaria saussurei Cooke, pro. tern. 



flsaria gracilis Vos. 



Entomogenous. Synnemata arising directly from the body of 

 the host, usually very long (20-30 mm.), flexible, somewhat 

 branched, more or less erect, brownish in color. Sporophores 

 simple, sessile, the basal portion inflated, short, tapering rather 

 abruptly to the usually very long (35-70 microns), slender sterig- 

 mata. Spores allantoid, 9-1 1 X microns, hyaline, imbedded 



in gelatinous matrices. 



Hosts: Polistes annularis (adult), North Carolina. 



Polistes sp. (adult), Hawaii. 

 Polistes sp. (adult), California. 

 Polistes sp. (adult), British West Indies. 



This species is readily distinguished from the others herein 

 described by its long, narrow, and usually allantoid spores, as 

 well as by its extremely slender sterigmata that are but slightly 

 swollen at the base. /. gracilis Voss. has been included as a pos- 

 sible synonym but as the description of this fungus includes no 

 discussion of the spores or other microscopic characters it is im- 

 possible to treat it more satisfactorily. 



3. Hirsutella floccosa sp. nov. 



Entomogenous. Synnemata short, verruciform, white, arising 

 from a cottony subiculum. Sporophores simple, sessile, ex- 

 tremely robust, the swollen basal portion tapering very gradually 

 into the short, rather stumpy sterigmata (10-15 microns) ; spores 

 fusoid, hyaline, 9-10 X 3.2-3.8 microns. 



Host : Pcregrinus maidis, Jamaica, B. W. I. 

 This species is somewhat unlike those described above, in that 

 the synnemata are merely wart-like outgrowths arising from an
