ASPERGILLACEAE 625 



Produces mat of mycelium covering the eardrum, which may be peeled 

 off with care. Best destroyed by Ca(0Cl)2 or dilute potassium arsenite. 



Has botanical characters of A. glmicus Link when grown on slices of citron 

 or sweet orange. Differs from A. fumigatus by yellow spores. 



The organisms mentioned by Lichtheim (1882) and others are supposed to 

 be synonyms of A. flavus or A. nidulans. 



Aspergillus diplocystis (Sartory, Sartory, Hufschmitt & Meyer) Dodge, 

 n. comb. 



Eurotium diplocyste A. Sartory, R,. Sartory, Hufschmitt & Meyer, C. R. 

 Soc. Biol. 104: 881-883, 1930. 



Cause of onychomycosis with inflammation and suppuration, first on 

 thumb, then on great toe. Mycelium and chlamydospores demonstrated in 

 nail. 



Conidiophores erect, 50-100/* high, 3.1-3.7/a in diameter, membrane thick, 

 hyaline. Phialides confined to a portion of head, 5-6.25 x 1.5-2.5/*. Secondary 

 phialides small, conidia spherical, 2.25-3.1/t in diameter, slightly ellipsoid, 

 green {tendre to cendre), phialides abortive and proliferous. Perithecia canary 

 yellow; asci 4-6 x 5-7/t, containing 8 ascospores which are ovoid, with a furrow 

 and two crests, 1.5-2.5 x 1.8-3.1/*. 



Colonies greenish yellow, becoming yellow from perithecia. 



Aspergillus luteus (Tieghem) Dodge, n. comb. 



Sterigmatocystis lutea Tieghem, Bull. Soc. Bot. France 24: 103, 1877; 

 Bainier, Bull. Soc. Bot. France 27: 30, 1880; Sartory & Jourdre, C. R. Acad. 

 Sci. 146: 548, 549, 1908. 



Caused death of rabbit on intravenous injection. Organism recovered 

 from kidneys and liver. 



Mycelium white, yellow, then turning green, erect conidiophores 300-800/* 

 high, with heads 12-30/* in diameter. Primary phialides 10 x 5-6/t, with 2-4-6 

 secondary phialides, 9 x 4/* in diameter. Conidia at first yellow then glaucous, 

 spherical, smooth. 3.5/* in diameter. On gelatin, agar or broth, growth be- 

 comes aspergilloid, optimum temperature 35° C. 



On agar, growth slow, white, yellow, then green. On potato, acid or 

 neutral, whitish hyphae appear at first, yellow on the second day, turn green 

 by the fifth, and the colony becomes folded. On carrot, growth is similar, but 

 mycelium remains flat, chlorine yellow on the seventh day, grass green on the 

 eleventh. On Raulin's medium, a mat, which becomes green and folded on the 

 second day. On neutral Raulin's medium, growth slower. In broth, conidia 

 slightly verrucose. Liquefaction of gelatin begins in 4 days, complete in one 

 month— Sartory & Jourdre.
