Lateral aleurospores and chlamydospores present. 



Cultures of Mahnstenia type, Avhite, surface powdery, as if a piece of silk 

 had been held by its middle and dropped, allowing it to fall into natural 

 wrinkles, the outer wrinkles radiating, the inner ones, less contorted than in 

 T. cerehriforme, margin powdery, less visibly radiating than T. flavum, occa- 

 sionally in old colonies the folds crack, but less completely and constantly 

 than in T. effractum.

Producing tinea tonsurans, common in Parma, and other cities of Northern 

 Italy, very rare in Paris, Kiel in Germany, and Hungary. 



Aleurospores lateral. Atypical closterospores reported by Catanei (1933). 



Colonies type of Trichophyton tonsurans, on maltose a button with the 

 center depressed with an elevated umbo, gradually disappearing as the colony 

 becomes folded and furrowed, suggesting T. effractum without the fractures, 

 color smoked brown of dead leaves, periphery often with concentric furrows 

 about 1 mm. apart, but this feature not constant. On Pollacci agar, surface 

 of irregular splintery elevations yellowish brown without a definite crater 

 or umbo. A central yellow border with radial furrows. Pollacci and Nan- 

 nizzi report appearance similar to that on Sabouraud agar. On Sabouraud 

 peptone, similar to Sabouraud maltose, but flatter, color gray. On barley, 

 colonies white powdery velvet.
