Aspergillus flavus De Bary, 1870. 



Synonyms. — Monilia aurea Gmelin, 1791 ; Eurotium flavum De 

 Bary, 1870; Aspergillus flavescens Wreden, 1874. 



Mycelium colourless; conidiophore hyphse terminate in roundish 

 formations of a gold-yellow colour. The conidia are dark yellow, 

 roundish, 5 to 7 in diameter, with a surface showing numerous 

 minute mammillar prominences. Found by several observers 

 (Wreden, Siebenmann, etc.) in the ear. Optimum temperature, 

 S7° C 



Aspergillus bronchialis Blumentritt, 190 1. 



Mycelium of a white colour, much ramified; conidiophore hyphae 

 are 6*2 to i2-6 jj, in diameter, 280 to 300 in length. Conidia 

 roundish, 3 to 4 in diameter, with a smooth surface, of a greyish- 

 greenish colour. This Aspergillus was found by Chiari in the 

 bronchi of a patient who had died from diabetes; it was investigated 

 by Blumentritt. It has not yet been found as a saprophyte. 



Aspergillus fontoynonti Gueguen, 1909. 



Found by Fontoynont and Carougeau in a European living in 

 Madagascar, who was suffering from multiple abscesses of the neck. 

 In the pus and in the first cultures obtained the fungus had no true 

 aspergillar appearance; it had to be subcultured several times 

 before the typical aspergillar fructifications appeared. Conidia 

 4 to 5 ^ in diameter, with surface finely verrucose. Optimum 

 temperature, 22° to 25° C. 



Aspergillus malignus Lindt, 1889. 



Synonym. — Eurotium malignum Lindt, 1889. 

 Colourless mycelium, composed of short articles. Conidiophore 

 hyphae erected, terminating in pyriform formations, 22 to 24 /j, in 



Fig. 532. — Aspergillus malignus Fig. 533. — Aspergillus repens

diameter, on which are situated the sterigmata, which are 10 ^jl long 

 and 4 to 5 in breadth. Conidia roundish, of a greenish-bluish colour.
