Isolated by Castellani from "blastomycosis" in Louisiana, organism 

 studied by Agostini (1932). Pathogenicity unknown. 



Hyphae 1-2/x in diameter, branching, often in fascicles ; conidial mycelium 

 4-5/t in diameter ; conidia pyrif orm, 5-7 x 3-5//, ; arthrospores present ; chlamy- 

 dospores 8-15ja, thick-Avalled, often with fat globules [mistaken by Castellani 

 for ascospores] ; found both on media and in host tissues. 



On Pollacci agar, colonies white, adherent, slightly fluffy. No growth on 

 blood agar. In liquid media, colonies coalescing into a mucilaginous mass. 

 Milk not coagulated, gelatin and serum not liquefied at first but later some 

 liquefaction takes place. No fermentation of any carbohydrates. 



var. mannitolfermentans Castellani, Jour. Trop. Med. Hyg. 36: 306, 1933. 

 Differs from the species producing acidity in mannitol but not in other 

 carbohydrates.

 1933. 



Isolated from a case of blastomycosis in Venezuela and from one in Cen- 

 tral America. 



Conidia ovoid, 7 x ^AAfx ; sterigmata up to 10.5/i. 



Colonies becoming dark brown or even black on glucose agar. Gelatin 

 rapidly liquefied. 



VERTICILLIEAE 



Mycelium hyaline or light colored, conidiophores differentiated, branched, 

 conidia borne in verticils. 



Key to Genera 



Conidiophores sterile on ends of main brandies, conidia borne singly on short flask-shaped 



side branches. Pachyhasium. 



Conidiophores not sterile on ends of main branches. 



Conidia and branches not surrounded bj- a gel, borne singly. 



Conidia spherical, ellipsoid, ovoid, clavate, neither cylindric nor elongate. 

 Conidia single on tips of branches, soon falling, not clavate. 



Verticillium. 

 Conidia clavate, single, terminal, fertile branches ending in two clavate cells, 



which are perpendicular to each other. Ferticilliopsis. 



Conidia ?)4 in a group at tips of branches. Cladoiotryum.
