ASPERGILLACEAE 637 



hypliae, spherical, 200-300/a in diameter. Asci 10.5-11/a in longest axis, 8-spored, 

 filling the perithecia. Aseospores purple brown, slightly ovoid, 4 x 5/x, with 

 a frill, giving the appearance of a biconvex lens, separating into two valves 

 on germination. 



Colonies on Czapek's solution agar, white to yellowish green or fairly deep 

 green, velvety to more or less floccose in purely conidial areas, becoming defi- 

 nitely floccose when perithecia are forming. In aseosporic strains, colonies 

 floccose with conidium production much reduced and green color absent or 

 nearly so. Reverse and medium usually reddish to dark red or red brown. 



Perfect stage of A. fumigatus described by Grijns, 1903, belongs here 

 (see Pinoy & Masson, 1915).

Diplosfej)hanus nidulans Neveu-Lemaire var. NicoUei Neveu-Lemaire, Precis 

 Parasitol. Hum. 101, 1921. 



Isolated from a case of Madura foot in Tunis. Tissues of the foot ex- 

 tensively invaded by the parasite. Puestow (1929) reports this organism from 

 a case of maduromycosis of the forearm and mycetoma back of the right ear. 

 (Organism determined by Thom as A. nidulans.) Not pathogenic to guinea 

 pigs or rabbits. 



Young mycelium colorless. Conidiophores erect, simple, continuous or 

 rarely septate, glaucescent or sometimes brownish, SOO/a long by 4/* in di- 

 ameter, head obconic, 12 x lO/x. Primary phialides 8 x 3/x with two, rarely 

 four, secondary phialides to each. These are 4 x 2.5/a, each giving rise 

 to a chain of conidia, spherical, 2-3/x in diameter, smooth or slightly roughened, 

 somewhat green. Chlamydospores terminal, spherical, 8-16/* in diameter, 

 brownish. Sclerotia black brown, 50-300/* in diameter, embedded in nests of 

 hyphae. Optimum temperature 36°-38° C. 



Var. Cesarii Pinoy & Masson, Bull. Soc. Path. Exot. 8: 11, 12, 1915. 



Caused mycetoma in the lung of an ass. 



Phialides often simple and inserted near the base of the vesicle. Conidia 

 3/* in diameter. Perithecia fertile, aseospores 4.1 x 4/*. Membrane turns brown 

 rapidly. 



Aspergillus unguis (Weill & Gaudin) Dodge, n. comb. 



Sterigmafocystis unguis Weill & Gaudin, Arch. Med. Exp. Anat. Path. 28: 

 463-465, PI. 12, 1919. 



Found on rather superficial lesions of nail of great toe in deeply penetrat- 

 ing brownish crevices of the nail, the remainder of which is deep yellow with 

 a marbled appearance resulting. 



Mycelium 2-5/* in diameter (mean 3/*). Conidiophores simple, nonseptate, 

 of uniform width, 250-300 x 5/*. Vesicle spherical, 12/* in diameter, or pyri- 

 form, 14-16 x 8/*. Primary phialides cylindric, 5 x 3/*. Secondary phialides 

 flask-shaped, 6/* long to the base of the neck and 3/* in diameter, four per
