and galactose" — Anderson [probably due to sugar impurities or perhaps 

 strains of Castellania faecalis]. Litmus milk alkaline but not clotted in 2 

 weeks. "Gelatin rarely liquefied" — Anderson. 



Syringospora Cavarae (Pollacci & Turconi) Dodge, n. comb. 



Cryptococcus Cavarae Pollacci & Turconi in Bencini & Federici, Atti R. 

 Accad. Fisiocrit. Siena X, 3: 746-766, 8 figs., 1928. 



Isolated from primary corneal lesions in Siena, Italy. Lesions reproduced 

 in the eye of a rabbit. 



Cells spherical, 4-7/*, or ovoid, 6-9 x 4-6/i, sprouting, wall thick, homo- 

 geneous or uniguttulate, rarely biguttulate, hyaline or yellowish ; later the 

 cells elongate to subcylindric 14-24 x 3-5/*, sprouting only from the apex, 

 forming a mycelium, septate, simple, or slightly branched. Blastospores in 

 small verticils of only a few cells each. 



On Pollacci agar, colony disciform, creamy, moist, milky white, then 

 slightly yellowish, slightly elevated in the center, plane, or more or less rugose. 

 Gelatin rapidly liquefied, milk not coagulated, no fermentation of sugars, 

 slight assimilation of glucose, fructose, maltose, and galactose. 



Syring-ospora Issavi (Mattlet) Dodge, n. comb. 



Monilia Issavi Mattlet, Ann. Soc. Beige Med. Trop. 6: 21-22, 1926. 



Case history not given. 



After 3 days at 37° C. in potato decoction, three types of growth: (1) 

 Blastospores, spherical, 5-6 fi, or ovoid, 7 x 4/*, containing a vacuole. (2) 

 Groups, sometimes in chains, of several elongate cells (6-8 x 2.5-3.5/*), bearing 

 at ends and at septa, spherical or ovoid blastospores. (3) Hyphae long, made 

 up of elongate and narrow cells (3.0 x 26.5/t), not much narrowed at the septa, 

 free ends rounded, with either spherical blastospores or other hyphae at the 

 septa. After 10 days the hyphae form a felt in whose interstices appear free 

 cells, some of which enlarge considerably, becoming, when ovoid, 8 x 4/*, and, 

 when elongate, 15 x 2.5/*. In some young hyphae the end of a cell swells. 

 After 30 days there is no further change. 



On Sabouraud agar at 37° C, colony white, somewhat shining, yellowing, 

 and thickening with age, becoming irregular with radiating striations at mar- 

 gin, giving a fringed appearance. Abundant growth of hyphae into medium, 

 giving it a granular appearance under a magnifying glass. On gelatin stab, 

 same appearance at surface, medium becomes cloudy beneath, with gas bubbles. 

 In potato decoction, flaky white sediment. Optimum temperature 37° C. 

 Litmus milk at first acid, then decolorized. Fermentation of glucose, fruc- 

 tose, maltose, galactose, sucrose, dextrin; none of lactose, mannite, inulin. 

 Milk coagulated. Slight evolution of gas with gelatin. 



Syringospora Negroni Dodge, n. sp. 



Cryptococcus sp. Negroni, Rev. Soc. Argentina Biol. 6: 648-652, 1930; Rev. 

 Univ. Buenos Aires II, 29: 360-364, Figs. 60-62, 1931.
