 brick red( ?), 70-80/x in diameter; vesicle 20-30/a in diameter. Primary phialides

This species belongs in tlie A. ochraceus group but dimensions are all 

 smaller. Aspergillus ochraceus has been reported from a case of otitis media by 

 Bellucci, but his description is too vague to be sure of the identity.

Isolated from human ear. This species belongs in the A. flavus group, but 

 has been too briefly described to identify with certainty. Conidiophores up to 

 4 mm. long.
