628 MEDICAL MYCOLOGY 



Isolated from a case of pityriasis versicolor fiava of brown spots with 

 discrete depigmentation and a few small vesicles at the borders. Reinocula- 

 tion into human skin gave typical lesion. On rabbit, scarification produced 

 epidermic lesions, while subcutaneous inoculation gave rise to subcutaneous 

 gummata, with the picture of generalized pseudotuberculosis revealed at 

 autopsy. 



Hyphae septate and branched ; conidiophores simple, 5/a in diameter, 

 vesicle 12 x 9/a. Primary phialides cylindric, 4/a long, bearing 2-3, sometimes 

 4 secondary phialides, 5-6/t long. Conidia spherical, 1-2/a in diameter, brown. 

 Other spores, borne laterally on short branches (phialides?), 3-4)u,. Chlamydo- 

 spores occasional. Under some conditions, only monstrous phialides are formed, 

 with a "pleomorphic" mycelium resulting. 



Aspergillus Hortai (Langeron) Dodge, n. comb. 



Sterigmatocystis Hortai Langeron, Bull. Soc. Path. Exot. 15: 383, 384, 

 Fig. 1, 1922. 



Found in a case of otomycosis in Brazil. Mackinnon (1932) refers this 

 species to A. terreus Thom. 



Conidiophore appears empty of protoplasm while neighboring cells ap- 

 pear full. Vesicle 5-10/i, in diameter, primary and secondary phialides 5 x 

 1.5/i,, scarcely covering upper half of vesicle. Primary phialides give rise to 

 two, occasionally three, secondary phialides. Conidia smooth, 2.5fi in diameter, 

 in long chains.

Sterigmatocystis antacustica Cramer, Vierteljahrschr. Naturf. Ges Ziirich 

 4: 325-337, PI. 2, 1859. 



Saprophyte, originally isolated from dates. 8. antacustica Cramer isolated 

 from external ear of man. Aspergillus niger Risel (1906) non al. from lungs 

 apparently belongs here. 



Vesicles 45/t in diameter ; primary phialides 20-50/x long, several secondary' 

 phialides to a primary phialide ; conidia 2.5-3. 5/i,. 



This species has often been confused with Aspergillus niger Tieghem by 

 subsequent writers, but differs in the much longer primary phialides. 



It is probable that Aspergillus nigricans Wreden, C. R. Acad. Sci. Paris 

 65: 368-370, 1867, belongs here, but it was too briefly described to place defi- 

 nitely. Apparently it was not cultivated.

This species is predominantly saprophytic but occasionally parasitic, es- 

 pecially in the human ear. Unless pathogenicity is clearly proved, reference
