THE ASPERGILLUS GLAUCUS GROUP 147 



(1930) isolated, in Brazil, A. amstelodami from a case of mycetoma of the 

 foot; and .4. keratitis Ball was described as on the cornea (Thorn and 

 Church, The Aspergilli, p. 86, 1926). There is thus data enough to justify 

 belief that an occasional strain of the A . glaucus group is found in connec- 

 tion with lesions in man. We know nothing of the manner of infection and 

 have no evidence that these organisms appear in any consistent manner as 

 pathogens. Quevedo's case in which A. maydis (1912) appeared as a cause 

 of poisoning of horses reads plausibly; this, however, is rendered doubtful 

 by the observations of other investigators who have reported in widely 

 separated places such masses of mycelium and spores without encountering 

 similar injury. A . fontoynonti of Gueguen (1909 and 191 1) isolated from an 

 abcess was not found pathogenic in subsequent animal experiments. 

 Species which grow well at blood heat have possibilities of pathogenesis; 

 fortunately, however, most members of the group do not grow at 37° C.
