ASPERGILLUS HERBARIORUM 



1029 



Pathogenicity. — This Aspergillus was found by Lindt in a case 

 of otomycosis; according to this author, it is very pathogenic for 

 rabbits. 



Aspergillus herbariorum Wiggers, 1780. 



Synonyms. — Mucor herbariorum Wiggers, 1780; Aspergillus 

 glaucus De Bary, 1870. 



MyceHum at first colourless, later yellow or reddish-yellow. This 

 Aspergillus is characterized by the large size of the conidia, which 

 are 9 to 15 ^ in diameter. It is in nature a common saprophytic 

 fungus. It has been found by Dunn in 1896 in the nasal cavities 

 of a man, and by Einhorn in 1900 in the vomit of a case of hyper- 

 chloridia. 



Aspergillus repens De Bary, 1870. 

 Synonym.^ — Eurotium repens De Bary, 1870. 



This fungus is very similar to A. herbariorum, but for the smaller 

 size of the conidia. Mycelium of a yellowish-green colour. Conidia 

 large, 7 to 8-5 /j,. Found by Sieben- 

 mann in the ear three times. Its 

 pathogenic role is doubtful. 



Quevedo has described an aspergillus very 

 similar to A . repens, which he believes to be 

 the cause of a type of encephalo-myelitis in 

 horses in South America. He calls the 

 organism A . mayidis.

strated, is now used to denote the (After Montoya y Florez.) 

 species of Aspergillus which is found in 



the pure violet variety of pinta. This fungus shows the typical 

 morphological characters of the genus Aspergillus. It grows easity 

 on various sugar media. On maltose agar the growth has at 

 first a whitish colour, which afterwards changes into greenish, to 

 become violet or greenish with a violet tinge at a later period. The 

 colour of the growth may vary according to the medium on 

 which cultivation takes place. The conidiophores are comparatively 

 thick; the conidia are globular, with a smooth surface. 



Several other species of aspergillar and aspergillar-like fungi are 

 found in pinta, but their botanical position has not yet been defined 

 with certainty.
