288 MEDICAL MYCOLOGY 



agar, hypliae 3-4.5/* in diameter, transparent, flexuous, up to 45/a long. Blasto- 

 spores showing nucleus and vacuoles 4/i in diameter. 



On Sabouraud glucose agar after 10 days, colony circular, 1.5 cm. in di- 

 ameter, surface flat, margin thinning, center slightly elevated, moist, grayish 

 yellow. On malt agar, in 10 days colony circular, 1.5 cm. in. diameter, yellow- 

 ish white, umbilicate, shining. By the twentieth day 2 cm. in diameter with 

 radiating rays which become closer together with age, surface moist, center 

 gradually depressed, medium not discolored. On glucose gelatin, at tenth day 

 colony round, 1 cm. in diameter, smooth, moist, sticky, grayish white. On 

 twentieth day colony same size with margins denticulate. On malt extract in 

 10 days, liquid cloudy and sediment present ; no pellicle or ring mentioned. 

 Acid production with fructose and mannose. Fermentation of galactose, 

 arabinose, xylose, rhamnose, and maltose. None with glucose (!), lactose, 

 raffinose, inulin, mannite, peptone, or starch. Gelatin not liquefied.

Producing interdigital blastomycosis among paper workers, locally known as 

 sadare, in the province of Gifu. In the manufacture of mino paper, the workers 

 keep their hands in water practically the whole day. Paper made from bark of 

 Broussonetia papyiHfera Vent, or Quercus glandulifera Blume, bark bleached with 

 CaOCl, washed thoroughly with water, then a maceration of the root of Hibiscus 

 japonicus Miq. or H. Manihot L. is added for the slime which holds the paper 

 fibers together and makes it suitable for umbrellas. In a village of 50 workers 

 examined, of 30 infected, most had used local remedies, juices of plants. Also 

 some attempt had been made at the factory by dipping the hands in CUSO4 

 solution or HgClj, the former ineffective, the latter effective in 1 :10,000 dilu- 

 tion. Organism was isolated from raw root of Hibiscus, from the preparation 

 used in paper making, as well as from the paper makers. Pathogenic for mice. 



Cells ovoid, thick-walled, 2 x 4-3 x 5/a, up to lO/i long. Optimum tempera- 

 ture 25°, growth very slow at 37° C. No asci seen. 



On glucose and malt agar, growth good, colonies round, yellowish white, 

 smooth, margins sharp, moist, shining, center slightly elevated, deeper col- 

 ored, whole colony browns in drying out. On carrot, growth good, yellowish 

 or clay color. On malt extract, turbid in 2-3 days, with sediment, but no pel- 

 licle or ring. Ferments maltose, mannose, fructose, glucose (one strain fer- 

 mented galactose and one strain raffinose) as does Mycelohlastanon cutaneum 

 (Fabry, etc.). 



Blastodendrion Arzti Ota, Derm. Woch. 78: 232-234, 1924. 

 On malt agar, cells ovoid or long ellipsoid, 2-6 x 3-10/i,, others 2-3 x 30-60/1 

 with rounded ends, one end usually rather thicker than the other, arranged 

 in loose chains ; other cells 10-20 x 3-5/i with pointed ends ; round cells have 

 one or two fat drops, long cells, many small ones. In hanging drop, branch- 

 ing chains are formed which cling together for several days. 

 Gas with levulose, sucrose, and raffinose only.
