EREMASCACEAE IMPERPECTAE 221 



Hyphae undulating, 2-4/x in diameter, arthrospores abundant and very 

 short; chlamydospores also produced. Asei [?] in tissues of experimental 

 animals. 



On glucose agar, colony fluffy, white or grayish white. No pigmentation 

 on mannitol agar. No fermentation or acidity on any carbohydrate. Milk 

 neither coagulated nor digested, but may become alkaline. Gelatin and serum 

 liquefied rapidly. 



Geotrichum versiforme Moore, Ann. Missouri Bot. Gard. 21 : 349-366, 1 pi. 

 1934. 



Isolated from thick, greenish, mucopurulent, at times bloody tenacious 

 sputum from a patient with bronchiectasis and pulmonary infiltration of sev- 

 eral years' duration. 



Organism varies in size and proportion on various standard media, at- 

 taining the largest cells on malt extract agar. Hyphae 3-8fi in diameter with 

 young cells approximately 6-40/x, long; arthrospores with abrupt or rounded 

 ends 4-9 x 6-18/t; round, thick-walled chlamydospores 4-18/x in diameter and 

 elongated, 6-8 x 20-30/a; small round cells 4-6/t in diameter, possibly blasto- 

 spores; conidium-like cells, round 4-6/a in diameter, pyriform 3-4 x 4-6/x. On 

 malt extract agar, cells spherical approximately 15/a in diameter ; arthrospores 

 6-9 X 12-18/x, also barrel-shaped cells and smaller spherical cells. Old cultures 

 show many arthrospores and fewer hyphae (Fig. 46). 



Colonies vary from dull grayish white, on Raulin's, Richard's, and Czapek's 

 agar, becoming light cream with age, to a dull cream to creamy-buff on 

 Sabouraud's, nutrient, glycerol, and lactose agar. On potato-dextrose, growth 

 grayish white to light cream, showing a plushlike whirl. Colony on malt 

 extract vermiculate or pebbled. Saboui'aud colony velvety, while cultures 

 on nutrient, lactose, and Endo's agar moist. Mycelium partially submerged 

 in Richard's, Czapek's and oatmeal agar. In broth, pellicle and a fairly heavy 

 sediment. No fermentation of sugars. Acid on maltose, galactose, d-mannose, 

 1-xylose, and fructose. No acid on lactose, sucrose, glucose, raffinose, 1-arabinose, 

 rhamnose, and inulin. Milk slowly acidified and coagulated. Plain gelatin 

 liquefied on surface after 12 days, beef-extract gelatin after 14 days. 



It seems probable that the following unnamed organism may belong here. 



Oospora sp. Bachmann, Centralbl. Bakt. I, 86: 129-132, 1921. 



This species is nearest to 0. lactis of Rabenhorst, Kryptogfl. Deutschl. 

 ed. 2. Metachromatic granules lacking near vacuoles. Oidia 7-10//, in diameter, 

 not multinucleate. 



Cultures, on maltose agar, gray white with seedlike surface. After 3 days, 

 colony becomes yeastlike near periphery, margin showing mycelium, with 

 cylindric or ovoid cells, 5-7/t long, occasionally chlamydospores up to lOfi with 

 highly refractive wall. Longer filaments in young agar colonies. On gelatin 

 plates, colonies as above, except that no filaments appear in 4-6 days. Myce- 

 lium 2/A thick. Fermentation slight except with maltose. Malt gelatin is 

 liquefied.
