Abstract
Twelve of 21 isolates of Cladosporium carrionii, when grown on nutritionally deficient media such as lactrimel agar, hay infusion agar, diluted corn meal dextrose agar and water agar, produced uniform phialides and phialoconidia identical with those produced by 2 isolates of Cladophialophora ajelloi. All isolates of Cladosporium carrionii and Cladophialophora ajelloi hydrolyzed urea in 7 days, but failed to liquefy gelatin. The decomposition of casein, xanthine, hypoxanthine and tyrosine was of no diagnostic value because of the variable results given by the isolates of Cladosporium carrionii. None of the Cladosporium bantianum isolates or commonly encountered saprophytic species of Cladosporium, such as Cladosporium cladosporioides and Cladosporium herbarum, showed the ability to form phialides on any of the media tested. Because of the identical nature of the 2 synanamorphs of Cladophialophora ajelloi, namely the Cladosporium-type and the Phialophora-type, with those of Cladosporium carionii, Cladophialophora ajelloi is considered to be a later synonym of Cladosporium carrionii. The Latin description of Cladosporium carrionii is emended to include the Phialophora anamorph.
