SPOROTRICHEAE 795 



This name is used for the organism in cases of maduromycosis with red 

 grains first clinically described by Carter in India and first cultivated by 

 Semon from the foot of an Indian soldier in the British army in France. 



Mycelium dichotomously branched with a "stippled appearance." No 

 chlamydospores found. 



On solid media, a central black zone with gray periphery which becomes 

 black in 10 days. In Kaulin's liquid, at the optimum temperature, 35° C, a 

 delicate, translucent, grayish, feathery growth appears. 



Perhaps the following unnamed species may belong here, or it may be re- 

 lated to Chalara. 



Oospora sp. Sartory, C. R. Soc. Biol. 84: 939-941, 1921. 



Mijcoderma sp. Sartory & A. Bailly, Mycoses pulmonaires 324, 1923. 



Isolated from sputum ; patient improved on medication with KI. Not 

 pathogenic for laboratory- animals. 



Mycelium white, becoming brown or chocolate color, 4:fi in diameter, sep- 

 tate, sinuous branched, walls slightly verrucose, conidiophores rigid, spores in 

 sinuous chains, yellow and brownish, ellipsoid 5.5-8.8/^, with granular contents. 



On agar, colonies convoluted, irregular, powdery, white, browning after a 

 week. On potato, brown, then mauve violet and reddish brown. On gelatin, 

 irregTilar white colonies, brow]i, powdery, mammillate, with white pellicle. No 

 growth on seiiim. Milk coagulated in 10 days, casein precipitated and digested. 

 No indol. No action on starch. Sucrose hydrolyzed in fermentation of sugars. 

 Gelatin liquefied. 



ACREMONIUM 



Acremonium Link, Mag. Ges. Naturf. Freunde Berlin 3: 15, 1809. 



The type species is Acremonium verticillatum Link. 



Hyphae branched, septate, repent; conidiophores simple, scarcely more 

 than short lateral branches, more or less erect bearing single solitary terminal 

 conidia which are hyaline or light colored, mostly ovoid and small (Fig. 119). 



This group has been isolated from deep-seated abscesses and from gener- 

 alized infection resembling sporotrichosis, so far reported only from the Ivory 

 Coast and once from France. 



Acremonium Muthuoni Fontoynont & Boucher, Ann. Derm. Syphiligr. VI, 

 4: 339-344, Figs. 9, 10, 1923. 



Found in abscess on the neck and arm which caused intense pruritus 

 Scratching caused flow of blood but no pus. After various antiseptics had 

 failed, the abscesses were excised. Mildly pathogenic to rat and guinea pig. 



Hyphae 1/i, in diameter. Conidiophores short, straight, or curved, 5-20/j 

 in diameter, swollen in the middle. Conidia 2.5-3/t in diameter, elongate el- 

 lipsoid.
