Nutritional physiology and taxonomy of human-pathogenic Cladosporium-Xylohypha species.
Physiological profiles of type, authentic and some additional isolates of Cladosporium-Xylohypha species of purported herpotrichiellaceous relationship are established. This group comprises melanized catenate hyphomycetes which are prevalently found on the human host. The species are excluded from the genus Cladosporium and are classified in the genus Cladophialophora. Taeniolella boppii is also transferred to this genus. Cladosporium bantianum (= Xylohypha emmonsii) and C. trichoides are considered conspecific and are now referred to as Cladophialophora bantiana. Meso-erythritol, L-arabinitol, ethanol and growth at 40 degrees C are found to be the most useful criteria for species distinction. The species Cladosporium carrionii is found to be heterogeneous. The anamorph of the saprophytic ascomycete Capronia pilosella is morphologically similar to an authentic strain of Cladosporium carrionii, but physiologically distinct. A diagnostic key for the recognized Cladophialophora species and to morphologically similar taxa is provided.
