F. Moustafa* & A. M. Abdel - Azeem Depar tment of Botany, Faculty of Science, Univer sity of Suez *Corresponding author: e-mail: Canal, lsmailia 4 1522, Egypt Moustafa_ [email protected] Received 26/6/20 I 0, Accepted 6/4 /2011 Abstract By screening of available sources of intormation, it was possible to tigure out a range of 310 taxa that could be representing Egyptian Ascomycota up to the present time. In this treatment. concern was given to ascomycetous fungi of almost all terricolous substrates while phytopathogenic and aquatic torms are not included. According to the scheme proposed by Kirk et a!. (2008). reported taxa in Egypt belonged to 88 genera in 31 families, and l l orders. In view of this scheme. very few numbers of taxa remained without certain taxonomic position (im:ertae sedis). It is also worthy to be mentioned that among species included in the list. twenty-eight are introduced to the ascosporic mycobiota as novel taxa based on type materials collected ti·om Egyptian habitats. The list includes also 19 species which are considered new records to the general mycobiota of Egypt. When species richness and substrate preference, as impotiant ecological parameters. are considered. it has been noticed that Egyptian Ascomycota shows some interesting features noteworthy to be mentioned. At the substrate level, clay soils. came first by hosting a range of I 08 taxa to Ilowed by deseti soils (60 taxa). At the taxonomic level, Sordariales. compared to other orders, accommodated the greatest number of taxa i.e. 92 taxa followed by Eurotiales (61 taxa). Chaetomiaceae and Trichocomaceae are by far the richest families by housing 61 taxa. At the generic level, Chaetomium occupied the tirst place among all reported genera by including 51 species followed by Arthroderma ( 15 spp.). Provisional keys to the identitication of reported taxa are given. Key words: Ascomycota. biodiversity, check-list, Egypt, fungi , taxonomy Introduction isolations from different sources.

Therefore, it should It is well known that microscopic characters of be mentioned here that, although the present study teleomorphs (perfect states) are considered by far the will add some new data to our information fundamentals for the identification of Ascomycetes. concerning the Ascomycota of Egypt, this updated However, associated anamorphs (imperfect states) check-list must be considered as a provisional one may be in some instances very crucial where they always waiting for continuous supplementation. serve as useful key characters especially in some For the ease of reference, collected names were genera like Arthroderma, Byssochlamys, Eurotium, sorted out into two main groups, the first comprised Neosartorya, Fennellia and Talaromyces.
