180 MEDICAL MYCOLOGY 



also on cartilage and maintained its distinctive characters. Yeast cell stage 

 unknown, probably not normally present, as the author states that the 

 chlamydospores germinate directly by germ tubes. 



The normal habitat of this genus is rather problematical. The cultures 

 were made before the technic of pure culture had been highly developed, so 

 that probably the cartilage had not been sterilized and the organism may have 

 been present in it, or it may have been present in the surrounding oil. It is 

 to be hoped that these organisms may be again encountered and studied. 

 There is no trace of sexuality observed, so that this may represent an end 

 member of a series. The relationship of Octomyces Froilano de Mello & Gon- 

 zaga Fernandes is also problematical. 



OCTOMYCES 



Octomyces Froilano de Mello & Gonzaga Fernandes, Arq. Hig. Pat. Exot. 

 6: 237-242, 1918. 



Mycelium septate, sprout mycelium also present ; asci 1-, 2-, 4-, and 8- 

 spored ; chlamydospores terminal. 



Type species Octomyces Bettencourti Froilano de Mello & Gonzaga Fern- 

 andes. 



The type was originally isolated from a contamination at Nova Goa, so 

 that nothing is known of its normal habitat. This genus may be considered 

 as a synonym of Oleina, but it differs in the absence of raquet mycelium, the 

 presence of sprout mycelium, and in the terminal rather than intercalary 

 chlamydospores, which seem to be produced only in liquid media. Both genera 

 have been rather poorly described and need much further study before their 

 systematic position will be known. Neither seems to have a well-developed 

 sexuality, such as found in Eremascus and Zymonema. 



Octomyces Bettencourti Froilano de Mello & Gonzaga Fernandes, Arq. Hig. 

 Pat. Exot. 6: 237-242, 1918. 



Isolated from contamination in a Petri dish, at Nova Goa. 



Mycelium septate, yeast cells spherical with brown granules, asci ellip- 

 soid, spherical, and lanceolate, 1-, 2-, 4-, and 8-spored. Chlamydospores 

 terminal, yeast cells not sprouting. 



On glucose and maltose agar, colony moist, dirty white streak, same 

 morphology as on potato. On potato, colony dry, veiy wavy, margins indented. 

 On carrot, culture dry, very wavy, dirty white, granular in appearance. 



In broth, easily dissociable pellicle and sediment, no turbidity, with no 

 fermentation, acid with dextrin, fructose, maltose, no action with lactose, 

 mannite, or glucose.
