788 MEDICAL MYCOLOGY 



Aleurisma salmoneum Vuillemin, C. R. Acad. Sci. 189: 407, 1929. 



A laborer in wine vaults showed on the anterior face of the right arm a 

 pustule, about 1 cm. in diameter, which had been the seat of a slight but 

 incessant suppuration for about a month. On pressure, lesion exuded a thin 

 pus, whose granules showed neither spores, grains, nor filaments. 



Cultures salmon color. If inoculation is deep, the surface of the agar is 

 smooth and mammillate; if superficial, the colonies are dull, rough, with a 

 deeper color. Aleurospores terminal, 4 x 2.3 — 10.5 x 4/i..

Found in tinea albigena. On soles or palms, little itching nodules appear. 

 These become vesicles 3-4 mm. in diameter, at first filled with an amber colored 

 liquid, then purulent and drying. In time, these vesicles are more frequent 

 and larger, followed by drying and keratinization. The epidermis becomes 

 very thin and easily torn, so that secondary infections frequently occur. 

 Finally, pigment is lost over the infected areas, which have expanded to in- 

 clude the lower arms and legs. This disease is widespread in the interior of 

 Java, Borneo, and Lombok, probably also in New Guinea and Sumatra. 



Mycelium of young cultures slender, 2/x in diameter, guttulate, cells 15-20/x 

 long, spherical or ovoid or elongate. Occasional lateral spores with or without 

 pedicel. In older cultures, spores more or less ovoid, 1-1. 5/x in diameter, lateral 

 with or without pedicel. No thyrses present — Nieuwenhuis. Hyphae 2-3/u., 

 rarely 3-5/*, in diameter, walls thin, covered with ver\^ fine rugosities. Inter- 

 calary spores present, 7-10/i, in diameter, coremium branching either perpen- 

 dicular or at an acute angle to the hyphae. Conidiophores simple or irregu- 

 larly branched, no verticils present. Aleurospores terminal or lateral, usually 

 sessile on conidiophore, usually solitary, occasionally in groups of two to three, 

 2-3 X 2-7/i,, thin-walled, not filled with granules. Very rarely there is a sug- 

 gestion of thyrses, but these are not well developed as in Microsporum. 

 Coremia bearing numerous aleurospores and chlamyclospores usually are present. 



Growth is slow, attaining a diameter of only 10 mm. in 21 days on the 

 first isolation. On Sabouraud agar, there forms an irregularly rounded disc, 

 4-6 cm. in diameter, after 42 days, clear chamois color in malt agar, coarse 

 velvety with numerous small coremia, 1-3 mm. long in center. As cultures 

 dry, medium becomes homy, white, with aerial mycelium appearing. Develop- 

 ment good on potato.
