MEDICAL MYCOLOGY 



I am doubtful whether this genus really belongs to the Eremascaceae. 

 Evidently a contamination, suggesting a primitive Basidiomycete or perhaps 

 an unreported member of the Tulasnellaceae which grew in the cultures. The 

 drawings do not suggest any other filamentous yeast. The mycelium is largely 

 of the raquet type, if the drawings are correct. 



MYCOTORULOIDES 



Mycotoruloides Langeron & Talice, Ann. Parasitol. Hum. Comp. 10: 48-54, 

 1932. 



The type species is Mycotoruloides triadis Langeron & Talice. 



Colonies creamy, thick, convex, beginning by bipolar sprouting of a blas- 

 tospore followed by progressive branching of the pseudomycelium. Blasto- 

 spores spherical or ovoid, arranged in verticils, arising at the apical portion of

the pseudomycelial cells, no terminal chains of cells. Pseudomycelium formed 

 of short cells, each cell producing a verticil of blastospores at its apex. The 

 verticils are less regularly spaced than in Syringospora and are usually com- 

 pound, producing an ovoid mass of blastospores whose long axis is more or less 

 perpendicular to the main axis of the pseudomycelium (Fig. 55). Some 

 branches develop more than others, giving an irregular appearance. Occasion- 

 ally a branch grows out and is terminated by short chains from its terminal 

 verticil. Gelatin not liquefied.
