| Popis: | Nearly 100 years after its first discovery, Diploöspora rosea was detected on biologically damaged parchment paper in Rome, Italy and isolated from house dust collected in Micronesia. The isolation of this culture permitted morphological study of colony characters, conidium and conidiophore development, and phylogenetic investigations using sequences of nuc 18S rDNA, internal transcribed spacers, and 28S rDNA. The results indicate that D. rosea is an onygenalean fungus, of uncertain taxonomic position, basal or sister to the Gymnoascaceae. Based on observations of the parchments using SEM-Energy Dispersive Spectroscopy, we speculate that the fungus occurs in archival and domestic environments subject to periodic wetting. Its ability to grow on all low water activity media used in the study, including malt extract agar amended with 60% sucrose, confirms its xerophilic nature. |
