drab, Ridgway). On glucose peptone medium, hyphae are white with a dark, 

 reddish-brown pigment diffusing into the medium. Milk neither acidified nor 

 coagulated. Gelatin and serum not liquefied. 



There seems little to differentiate the followng species from this but, since 

 it is so much more fully described, 1 hesitate to reduce it to synonymy without 

 further evidence. 



Trichosporium Clapieri (Catanei) Dodge, n. comb.

Isolated from a black grain tumor of the maxillary region. The grain in 

 section suggested Madurella in appearance. 



Mycelium septate, 2.5-3//, in diameter, brownish with occasional coremium 

 formation, aleurospores terminal or lateral and sessile, on branches, smooth, 

 ovoid, truncate, 6.5-9 x 5-6. 5/a. Chlamydospores 10.5-15 x 9-15/^, intercalary or 

 terminal, brownish black. Growth best at 37° C. 



On Sabouraud glucose agar, colony black, slightly shining, with little 

 pointed black coremia, 1-2 mm. tall, finally covered with a gray velvet, some- 

 times rough, with a black border, center elevated, colony deep in the gel and 

 adherent. On ordinary agar, colony is deep brown, almost black, covered with 

 coremia, 0.5 mm. tall, whole colony becoming 2-2.5 mm. thick with the medium 

 brownish around the colony. On potato, colony deep gray with a velvet finer 

 than that on Sabouraud glucose agar. On ageing it is slightly pulverulent, 

 brown, with the color of the substrate not modified. On potato glycerol, sur- 

 face is black, shining, irregular. On carrot, growth is about the same as on 

 potato. On coagulated serum, colony small, elevated. On gelatin, both super- 

 ficial and deep colonies. In peptone water, there appear small tufts, gray in 

 color at first, then deepening, small ring, no turbidity. Milk is not coagulated, 

 but turns alkaline after one week and continues to turn. Neither coagulated 

 serum nor gelatin liquefied. 



Doubtful Position 



Glenospora g-andavensis Vuillemin, C. R. Acad. Sci. 173: 378, 1921. 



Isolated from sputum, Ghent, Belgium. 



Chlamydospores 6-10 x 5-8/a; hyphal cells 8-13 x 1.6-3.5;u,, branching in all 

 directions. Hyphae hyaline, without chlamydospores in Veillon agar, in low 

 oxygen tension. Growth good at 20°-37°, optimum 32°-35° C. 



On Veillon stab, surface growth only. On maltose agar, a central black 

 dome with clear fringes. Growth on carrot blackens on the fourth day, shows 

 chlamydospores on the fifth.
