Hyphae about 2/x in diameter, irregularly staining with Gram '^s stain. My- 

 celium formed of parallel strands of curved liyphae, few or no lateral branches. 

 Spores rare along the hyphae, usually terminating them, 3-5ju, in diameter, ovoid 

 or apiculate (Fig. 122), staining with Gram stain. 



Optimum temperature 30° -38° C, growth slow at room temperature. Colo- 

 nies show straight furrows, not cerebriform. Lactose fermented, not sucrose. 

 Culture remains colorless indefinitely, with a brownish pigment developing in 

 the aerial portions. Spores hyaline, aerial fructification normal. In deeper and 

 moister portions of the cultures, spores sprout below into short, irregular chains, 

 5-8 spores long. — Matruchot. 



The following data come from the original description. Colony on agar 

 white, wrinkled, becoming brownish or even dark brown and velvety. Growth 

 on potato yellow, becoming brown, medium darkening. Tufts of mycelium ap- 

 pear in broth, also islets on the surface. Litmus milk is unchanged, with little 

 growth occurring. No fermentation, no liquefaction of serum. Gelatin slowly 

 liquefied. 



Chlamydospores appear in media poor in nutrients, but are not abundant, 

 as in some strains of Sporotrichum Beurmanni. Davis (1914) believes that 

 the chlamydospores do not afford a sufficient criterion for the separation of 

 these two species.

Isolated from the pus in small tumors in the subcutaneous tissues. Tu- 

 mors possess definite walls, become about the size of a peach stone, are at first 

 painless, later becoming painful on pressure, finally filled with odorless, 

 granular pus. 



Mycelium recumbent, 2/x in diameter, colorless, much branched, tangled. 

 Fructifications are composed of large, cylindric masses, lOjji in diameter, some- 

 times elongated. Spores terminal on long hyphae or on branches, solitary.
