650 MEDICAL MYCOLOGY 



Sporendonema epizoum Ciferri & Redaelli, Jour. Trop. Med. Hyg. 37: 167- 

 170, 1934; Redaelli & Ciferri, Atti 1st. Bot. R. Univ. Pavia IV, 5: 145-198, 1934. 



Isolated from small, indolent nodules which become ulcers with blackish 

 crust, 1.5 cm. in diameter. Nonpathogenic to guinea pigs, pathogenic to white 

 rats; lesions similar to those produced by Sporotrichum. It is possible that 

 some of the Italian cases referred to Hemispora stellata should be referred 

 here. Cerri (1932) identifies this organism with Torula Sacchari Corda. 



Hyphae septate, branched, 2.5-3/i. in diameter, forming a mat 90-100/i 

 thick ; conidiophores erect 50-60/x high, densely fasciculate, flexuous, sparingly 

 branched, 2.5-3.5/a in diameter, 50-60/i, high at first, becoming 150-160/a, hyaline 

 or subhyaline, minutely guttulate, sparingly septate, chains of conidia, 6-8 

 cells, developing slowly in the phialides and hanging together for a long time ; 

 conidia spherical 2.5-3.5/* smooth, uniguttulate, ochraceous at first becoming 

 olivaceous; chlamydospores intercalary, hyaline, 8-lO/t. 



On Sabouraud glucose agar at 22° C, colonies grayish at first, becoming 

 mammillate, grayish brown with brownish or chocolate powder, finally cere- 

 briform and confluent. On glucose broth, chocolate brown, powdery, super- 

 ficial, brown sediment but no true pellicle. 



Doubtful Position 



The following species are either too imperfectly described to place ade- 

 quately or I have been unable to locate the original descriptions. 



Scopulariopsis Vignolo-Lutatii (Matruchot) Dodge, n. comb. 



Acaulium Yignoli-Lutatii Matruchot apud Vignolo-Lutati, Arch. Derm. 

 Syphilis 118: 681-698, PI. 21, 1 fig., 1913. 



Isolated from lesions on skin following wound with acacia thorn, Novara 

 Province, Italy. Lesions clinically suggest sporotrichosis or tuberculosis. 

 Pathogenic for guinea pigs. 



Mycelium of branched, hyaline, septate hyphae 2-3fx in diameter, not 

 fasciculate. Phialides simple or in groups of two or three, 10-15 x 4/x ; conidia 

 in chains of 8-10, blackish brown. 



Colony on Sabouraud glucose or maltose agar more or less cerebriform, 

 center becoming very dark brown, outer zone yellow. 



Scopulariopsis americanus Ota, Jap. Jour. Derm. Urol. 28: 4: [7], 1928, 

 nom. nud. [figured and perhaps described in the Japanese text] ; Ota & 

 Kawatsure, Arch. Derm. Syphilis 169: 160-163, Figs. 4-6, 1933 [citing Ota, 

 Jap. Jour. Derm. Urol. 26: 1:111, 751, 1926, as place of original publication, 

 but I have been unable to see this publication]. 



American oidiomycosis. Cultures of Weidman 1135, 1136, 1233, and 1234 

 (Ota collection 538, 539, 540, 541). Kawatsure (1933) reports pathogenicity 

 for mice, white rats, guinea pigs, and rabbits. 



Mycelium produces irregular arthrospores [suggesting those of Madur- 

 ella] • conidia in chains of 3-4 spores on short side branches or more often
