ASCOMYCETES AND BASIDIOMYCETES 



Aspergillus boulfardi Brumpt, 1905. 



Found by Bouffard in a case of black mycetoma, and completely 

 described by Brumpt. Mycelium whitish in some zones, dark 

 brown in others. Conidiophores erect, white, each terminating in a 

 claviform structure, bearing some short chains of roundish conidia. 

 Conidia i'3 to 2 in diameter, roundish with a smooth surface, white. 

 Chlamydospores present, 5 to 10 /,t in diameter. Attempts at 

 cultivation did not succeed. 



Aspergillus barbae Castellani, 1907. 



Found by us in natives of Uganda, and in natives of Ceylon. Conidia 

 spherical, 4 to 5 yW, of a brownish colour. 



Aspergillus nigrescens Robin, 1889. 

 Doubtful species, which, according to Wienfeld, causes a faviform eruption. 



Genus Sterigmatocystis Cramer, 1859. 



Definition. — Aspergillales with conidiophores terminating in 

 roundish or ovoid formations, on which are situated short cylindrical 

 s! ructures — primary sterigmata — surmounted by similar elements- — 

 secondary sterigmata. Each of the secondary sterigmata supports 

 a chain of roundish conidia. 



Remarks. — The genus w^as created by Cramer for a fungus found 

 in a man's ear. 



Type Species. — Sterigmatocystis antacusiica Cramer, 1859. 

 Classification.— The two species of importance to us can be 

 recognized as follows: — 



A. Young conidial forms green; later strongly grey to brown. Conidia 



small, 3 microns in diameter — Nidulans. 



B. Conidial forms blackish brown. Conidia small, 2-5 microns in 



diameter — AntacusHca. 



Sterigmatocystis antacustica Cramer, 1859. 



Synonyms. — Sterigmatocystis antacustica Cramer, 1859; Eurotium 

 nigrum De Bary, 1870 ; Monilia pulla Persoon ; Aspergillus nigricans 

 Wreden, 1874; A. niger von Tieghem, 1867. 



Primary and secondary sterigmata; erected conidiophores; 

 hyphse more than i millimetre in length (3-5 to 4*5). Conidia 

 globular, 2 -5 in diameter, provided with a membrane of a brownish 

 colour. Commonly found in decaying organic substances. It was 

 first observed in man by Cramer, who observed it in the ear of a 

 deaf patient. Later it was observed by Furbringer and others in 

 mycotic affections of the lungs. 



Sterigmatocystis nidulans Eidam, 1883. 



Synonym. — Aspergillus nidulans Eidam, 1883. 

 Mycelium of a greenish colour. Conidiophores are erect, o»5 to 

 0'8 millimetre in length. Presence of primary sterigmata, sup-
