A total of 218 species and 3 varieties belonging to 83 genera of filamentous and yeast fungi were recovered from the air of both citrus and grapevine plantations. A relatively higher numbers of genera and species were recovered from the air of citrus plantations compared with those recovered from grapevine plantations. The peak of total propagules of fungi caught from the air of citrus plantations was shown in February on both media and from the air of grapevine in December and August on DYM and DRBC, respectively. Their troughs were shown in June and October on DYM and DRBC, respectively for both citrus and grapevine plantations. The widest spectrum of species recovered from the air of citrus plantations was registered in June on both media and from the air of grapevine plantations in February and in April on DYM and DRBC, respectively. The air of citrus plantations shared the air of grapevine plantations in some highly encountered filamentous fungi on both media (Cladosporium, Penicillium, Aspergillus and Alternaria) or on one medium (Cochliobolus, Fusarium, Myrothecium, Phoma and Pleospora). Eighty-four fungal species were isolated from the air of citrus only, while 46 species were isolated from the air of grapevine only.Yeast fungi showed their peak of total propagules from the air of citrus plantations in October and April and from the air of grapevine plantations in June and December on DYM and DRBC, respectively. Fifteen genera and 26 species of yeasts were collected. Two genera of yeasts were encountered in high frequency on one medium and moderate or low on the other medium in the air of both citrus and grapevine plantations and these were Cryptoccocus (4 species) and Rhodotorula (3 species).

During surveys of the mycota inhabiting guts of some insect species in Assiut area, Egypt, an interesting isolate of a dematiaceous hyphomycete was obtained from a gut sample (out of 11 investigated) of the red palm weevil, Rhynchophorus ferrugineus. This isolate was morphologically and genotypically identified as a new species in the genus Triadelphia (Triadelphia moubasherii Abdel-Sater and Zeinab Soliman, with 94 % ITS similarity with T. disseminata Madrid & J. Edathodu, GenBank accession no. KC489510). The type strain of the new species was deposited at Assiut University Mycological Centre Culture Collection and given AUMC number 10746 and the ITS gene sequence was deposited at the National Center for Biotechnological Information (NCBI) and accession numbers is given as KY611849. Description and photos of the new species are presented.
During the mycological analysis of skin and nail samples taken from patients with
onychomycosis and tineas in Assiut city, it is interesting to report that yeast fungi
were the main causal agents being cultured from 45.79% of total cases. In general,
21 species of yeast were isolated. Some of these are reported for the first time from
clinical specimens. From the literature available up-to-date around the world, this
study reports for the first time Saccharomycopsis fibuligera as the causal agent of four
clinical cases: two onychomycoses, one tinea capitis and one tinea amiantacea. Also,
it is reported here the second record for Trichosporon dohaense from a case of onychomycosis
of a 40-year-old woman (after its original description in 2009 by Taj-
Aldeen et al. J Clin Microbiol 47: 1791). Candida galli was also reported for the first
time from clinical specimen (tinea unguium) in 2014 by Galan-Sanchez et al. Mycopathol
178: 303, and this study reports the second case of onychomycosis by
C. galli. These strains were identified on the basis of their phenotypic, biochemical,
physiological and genotypic features. Strains and internal transcribed spacer (ITS)
gene sequences of these species are deposited at Assiut University Mycological Center
Culture Collection (AUMC) and National Center for Biotechnological Information
(NCBI) respectively.
