Found in widespread lesions, closely resembling syphilitic gummata, on 

 skin, bones, etc. Medication with large doses of KI promptly cleared up the 

 lesions. Probably the case of Bedell (1914), from the eye, should be referred 

 here. 



Cultures of this organism show all stages between blastospores fonned 

 directly on conidia and well-developed mycelium. Occasionally, one spore has 

 four spores attached by sterigmata or by a short germ tube, bearing the tuft 

 of spores on its end, as in smuts. Mycelium, as usual in Sporotrichum, com- 

 posed of elongate tine filaments, abundantly branched, tangled, septate; spores 

 either in small tufts or isolated along the filaments. Tufts either terminal or at 

 the ends of short, lateral branches. Each spore, borne on a short sterigma, 

 brownish and spherical when detached. Tufts usually only 4-5-spored. Hyphae 

 1.5-2/x in diameter, spores 2.5-3.5/x in diameter, sterigmata 1-1.5 x 0.5-0.85/a. 

 Sporotrichnm homhycimon Corda differs in having filaments thicker, spores 

 hyaline, attached singly to branches 15-26/^ long and of nearly the same diameter 

 as the principal filament. ^S^, Beurmanni has mycelium more slender and more 

 abundant, 1.5-1.7/x in diameter. Short forms exceptional. Tufts of spores 

 larger, containing 12-15 spores. Lateral spores closer together, ellipsoid, 3.5 

 X 2.6/x, or pyriform, 4 x 2.4a'- 



On most media, colonies compact, resistant, adherent. Organism grows 

 on usual media. Growth best at 35°-37° C. On Sabouraud maltose agar, 

 growth tomentose. On glucose peptone agar (first isolation), growth in 8 

 days, center of colony smooth, then a ring of striate radiating crests and out- 

 side a "crown of rays." Colonies cream color to old ivorJ^ On potato with- 

 out glycerol, white velvety colonies on fourth to eighth day. Thirty-four days 

 later, colonies size of lentils, flat, furrowed, with radiating folds and little 

 sharp peaks. On potato glucose in incubator, growth visible on sixth day, 

 cream white, blackening on fourteenth day. On thirty-fourth day, surface cov- 

 ered, coal black, in hollows, slightly ashy, powdery on ridges. On carrot, 

 white colonies, becoming black with white border. Growth much slower than 

 on potato. On gelatin, smooth pearly little points on the surface, radiating 

 and filamentous on walls of the tube after 3-4 weeks. Center of colony a 

 conic umbo ; periphery, a white zone with fine striations at bottom of a deep 

 umbilical depression. In broth, a fragile pellicle composed of small white 

 nodules surrounded by rays, mediiun remains clear. Gelatin not liquefied.
