Abstract

During a survey of phyllosphere and non-rhizosphere soil fungi of orange plantations in the Assiut area, Egypt, several isolates of species of Aspergillus belonging to the section Usti were isolated at 25 °C. These were identified using phenotypic and genotypic characters as Aspergillus porphyreostipitatus and Aspergillus carlsbadensis. To the best of our knowledge, these are the first global records since their original descriptions and indicate their probable wide distribution. The strains of both species could grow at 37 °C (a character contrasting to that of the original description of A. carlsbadensis), but both were not able to grow on CYA at 5 °C or 45 °C or to produce acid on creatine. It is interesting to report that both strains produced the urease enzyme (however weakly in A. porphyreostipitatus) and failed to grow on G25N at 25 °C, characters not examined in the original descriptions.
