Resumen:
Scedosporium, Acremonium, Phialemonium, Lecythophora and Paecilomyces were studied. In Scedosporium, the study has focussed on choosing the best tool for the characterization of S. aurantiacum and S. prolificans. As for the other genera, studies have focussed on morphological and molecular identification. The results showed that the system based on multilocus sequencing is the best methodology for the characterization of Scedosporium. By correlating the results obtained by morphological and molecular techniques, we have been able to establish the species associated with clinical samples from the United States, Acremonium kiliense, complex Acremonium sclerotigenum-Acremonium egyptiacum, Acremonium implicatum, Phialemonium obovatum, Phialemonium curvatum, Lecythophora hoffmannii, Cephalotheca foveolata and Lecythophora mutabilis being the most found species. We proposed Phialemoniopsis as a new genus. We transferred Sarcopodium oculorum and Phialemonium curvatum to Phialemoniopsis, and Acremonium atrogriseum and Taifanglania inflata to Phialemonium. We proposed the new species: Phialemoniopsis cornearis, Phialemoniopsis pluriloculosa, Phialemonium globosum, Lecythophora luteo-rubra, Lecythophora cateniformis and Paecilomyces lavendulus.
