Abstract: By screening of available sources of information, it was possible to figure 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 forms are not included. According to the scheme proposed by Kirk et al. (2008), reported taxa in Egypt belonged to 88 genera in 31 families, and 11 orders. In view of this scheme, very few numbers of taxa remained without certain taxonomic position (incertae 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 from 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 important 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 108 taxa followed by desert 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 first place among all reported genera by including 51 species followed by Arthroderma (15 spp.). Provisional keys to the identification of reported taxa are given. Key words: Ascomycota, biodiversity, check-list, Egypt, fungi, taxonomy
