536 MEDICAL MYCOLOGY 



Atrichophyton Blanchardi Castellani & Chalmers, Man. Trop. Med. ed. 3, 

 1008, 1009, 1919. 



Unable to cultivate, mycelmm easily breaking- up into arthrospores, cells 

 often banana shape, spores round, not in chains. Isolated from glabrous skin, 

 lesions brown, fine scales and vesicles, no papules, great pruritus. Possibly 

 a Malassezia.

 202, 1916. 



Oidium epitheliomae Greco, 1910 [ ? MS name] . 



Isolated from a nasal abscess. The lesion gradually spread to the adjacent 

 regions of the face as large ulcers, fatal in about 2 years. On rats and mice 

 it produced lesions similar to those produced by Sporotrichum. 



Mycelium branched, septate, 2/a in diameter, producing terminal chains 

 of 5-6 ovoid spores 2-3/a. The sporiferous hyphae are often branched and bear 

 chains on the lateral branches. Coremia of sterile hyphae common. On solid 

 media, arthrospores common in moniliform chains about 4/x, in diameter. 



On simple agar, colonies whitish, radiating from a grayish point, becom- 

 ing dull white, margin of fine adherent rays, finally covered with a light 

 chestnut powder. On Sabouraud agar, growth similar to preceding but more 

 luxuriant, undulating, dull straw white, the medium becoming straw-yellow. 

 Marginal rays filamentous. Coremia present. On carrot, and potato, colonies 

 radiate, white or grayish white, with aerial hyphae, which tend to form a uni- 

 form layer over the colonies, with a yellowish color in the depths. On simple 

 broth and glycerol broth, colony forms a dull white pellicle, covered with a 

 dull grayish white powder. 



While this is too poorly described to place definitely, it apparently be- 

 longs either in Zymonema or in Proteomyces. It is certainly not a species of 

 TrichopJiyton. 



Trichophjrton lileum Kawasaki, 1923. 



Trichophyton inflatum Fiocco & Minassian apud Fiocco, Giorn. Ital. Mai. 

 Ven. Pelle 51: 189, 1910; Sabouraud, Maladies du cuir chevelu 3: 581, 1910. 



Colony cerebriform, powdery, crackled, center inflated, whitish. 



Perhaps near T. fumatum. 



Trichophyton spongoides Fiocco & Minassian apud Fiocco, Giorn. Ital. 

 Mai. Ven. Pelle 51: 190, 1910; Sabouraud, Maladies du cuir chevelu 3: 581, 

 1910. 



Colony bister, neutral, not powdery, center elevated, suggesting a brown 

 sponge placed on a powdery, crackled disc.
