Abstract
Abstract : This study is carry out, to identifying and the diversity of fungal flora in the 15 samples of carpets used in selected and common rooms in Hilla city .The result showed that the frequencies of occurrence of Phyla – Group are 100% of Ascomycota followed by Zygomycota were 26.7 %. The highest widespread fungal genera in frequencies of occurrence fungi were those belong to the genus Cladosporium was 93 .3 % was the most ubiquitous of the genera then the Aspergillus and Pencillium were 66.6 % and 60 % respectively while the lowest widespread the Helicomyces was 6.66 % . The highest frequencies of occurrence of percentages the species Cladosporium cladosporides was 93.3 % than Pencillium chrysogenum wes 33.3% followed the species Aspergllus niger , A.carponarius , A. flavus , and Pencillum sp2 were 26.7 % . Also showing the percentages of the relative dominance , the highest genera ware recorded in Yeast, Cladosporium were 36.41 % and 34.23% respectively, followed by Aspergillus and Pencillium 9.78 %and 9.51% respectively. While, there were differences in fungal species associated with each of the samples .Also, showing the percentages the highest relative dominance of the species were recorded in Yeast, Cladosporium were 36.41 % and 34.23% respectively, followed by Pencillum chrysogenum and A. versicolure were 7.88 % and 4.62 % respectively. Presents the values of four different diversity indices calculated for the 15 samples under study . The Simpsons diversity index (D) was the lowest in the in the samples 7, 1 and 6 were 0.071, 0.091 and 0.100 respectively followed the samples 2, 8 and 10 with the same index were 0.143 , while the D was the maximum in the sample 15 was 0.706 . The D value for the other samples is reasonably varying from 0.467 - 0.695 . When the Shannon values (H) show an increase is reasonably high varying from 0.066 to 0.753 correspondingly the Simpson's values are low varying from 0.071 to 0.706 . The H index in the other samples were low while the D index was the high indicating less diversity in these samples or when the D index was the low in the same samples indicating high species diversity . The richness index (R) in most the samples indicates many species with maximum diversity. The evenness index indicates that species were fairly evenly distributed except the samples 3 and15 .
