MEDICAL MYCOLOGY 



Conidia cylindric or fusiform, elongate. 



Conidia acrogenous, single. Acrocylindriwrn. 



Conidia several on the tips of the branches. 



Tips of branches swollen. Calcarisporium. 



Tips of branches uncinate. TJncigera. 



Tips of branches neither swollen nor uncinate, sterigmata in a single row on 

 one side. Coemansia. 



Conidia and branches more or less surrounded by a gel. 



Conidiophores several times verticillately branched. Acrostalagmus. 



Conidiophores with an unbranched main axis on which the small side branches are 

 borne. 

 Branches perpendicular, like sterigmata, simple with a small head of conidia. 



Harziella. 

 Branches short, ovoid, conidia single. Gloiosphaera. 



Conidia borne in chains (sec also Penieillimv, etc.) Spicaria.

No clear-cut pathogens are yet known from this group. Verticillium is 

 the only common contaminant (Fig. 134). The position of Spicaria is not clear. 

 Some have considered Scopulario'psis a synonym, in which case it should be 

 transferred to the Aspergillaceae. Some species were originally described as 

 Penicillium. Many of the species have not been adequately figured, so that one 

 cannot be sure that the spore chain is formed in the same way as that of the 

 Aspergillaceae, but it is very likely that such is the case. For the present, 

 we have retained it as a separate genus and are treating Spicaria rubra from 

 corneal lesions at this point.
