Since Pier Antonio Micheli described and published genus Aspergillus in Nova Plantarum Genera in 1729 the genus attracted an immense interest. The published Egyptian literature on the genus is scattered and fragmentary. By screening the available sources of information since 1921, it was possible to figure out a range of 150 taxa that could be representing genus Aspergillus in Egypt up to the present time. Ten species of Aspergillus were introduced as type materials from Egypt since 1964 till now.Recorded taxa were assigned to 5 subgenera and 25 sections. This article includes Aspergillus species that are known to Egypt, provides a comprehensive checklist of species isolated from Egypt and provisional key to the identification of reported taxa is given. Although the present study will add some new data to our information concerning the Ascomycota of Egypt, this work must be considered as a provisional one always waiting for continuous supplementation.
The study is conducted in two growing areas of garden pea (Pisum sativum L.) in northwestern Algeria. Damages caused by Ascochyta sp complex are important in particular for the variety of Kelvedon Wonder. Observations carried out on the infected plants for several years, indicate the presence of superimposed necrosis of different sizes on all aerial organs. However, these observations do not differentiate symptoms by species. The results of morphological and molecular characterization with sequencing in internal transcribed spacer (ITS) regions and inoculation tests on 32 isolates in the laboratory of symbiosis and plant pathology from Toulouse (France), show a reconciliation of the sequencing by polymerase chain reaction (PCR) products and size necrosis for all Ascochyta pinodes and pinodella. Alone, Ascochyta pisi is distinguished by a smaller size necrosis. On the molecular level, all isolates whose ITS regions were amplified by PCR, expresses similar size products (550 bp). This molecular weight is found on a large set of pathogenic fungi. The three species of Ascochyta sp complex do not exhibit polymorphism for Pisum sativum species and have an identical molecular weight. The pathogenicity tests performed showed differences in aggressiveness on the host plant. Ascochyta pinodes is the most aggressive than the other two species. As a result, it causes more damage to the crop.

An annotated check-list of Ascomycota reported from soil and other terricolous substrates in Egypt2011 •
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.

Aspergillus creber and A. keveii, two new records as endophytes from wild medicinal plants in Egypt2020 •
In the present research and during surveys of mycobiota inhabiting leaves and roots of some wild and medicinal plants in El-Kharga Oasis, New Valley Governorate, Egypt, two significant isolates were isolated for the first time in Egypt and for the second time worldwide after type species inhabiting leaves of Convolvulus arvensis and Moringa oleifera. Those isolates were phenotypically classified as Aspergillus creber, and A. keveii referred to the representative type species belonging to the genus Aspergillus section Versicolores and section Usti, respectively. Pure cultures of both species have been deposited in the Culture Collection of Assiut University Mycological Centre with A. creber AUMC 14298 and A. keveii AUMC 14299. Their identification was verified by molecular recognition based on the sequencing of the ITS gene for each. Sequences of the two fungi's ITS genes have been submitted to GenBank with respective accession numbers MN542346 and MN542353, respectively. These species are recorded here for the first time worldwide as endophytes. The current research provides brief descriptions and photographs of both species.

Some interesting species of the genus AscochytaThe paper presents eleven species of Ascochyta recently collected in central and southern part of Poland. Two of them, Ascochyta bondarceviana Melnik and Ascochyta equiseti (Desm.) Grove noted in Poland for the first time, are illustrated with microphotographs. In addition, nine other species are newly reported on their host plants species in the country. Short characteristics of the fungi species based on the collected specimens and the distribution maps of all fungi taxa are presented.
Some fungal species were isolated from scab or scab-like symptoms on leaves of various plant hosts in Iran. Some of them isolated from apple and pear leaves were investigated in the present study. The isolates were identified based on the morphological and cultural characteristics. On the other hand, for molecular identification and phylogenetic analyses were carried out based on the sequence of ITS-rDNA region (including 5.8S rDNA). As a result, six species, namely Acremonium fusidioides, Acrostalagmus luteoalbus, Clonostachys rosea, Sarocladium kiliense, Sarocladium strictum and Endoconidioma populi were identified. Among them, Acremonium fusidioides is a new taxon for the mycobiota of Iran.

The history, fungal biodiversity, conservation, and future perspectives for mycology in Egypt2010 •
Records of Egyptian fungi, including lichenized fungi, are scattered through a wide array of journals, books, and dissertations, but preliminary annotated checklists and compilations are not all readily available. This review documents the known available sources and compiles data for more than 197 years of Egyptian mycology. Species richness is analysed numerically with respect to the systematic position and ecology. Values of relative species richness of different systematic and ecological groups in Egypt compared to values of the same groups worldwide, show that our knowledge of Egyptian fungi is fragmentary, especially for certain systematic and ecological groups such as Agaricales, Glomeromycota, and lichenized, nematode-trapping, entomopathogenic, marine, aquatic and coprophilous fungi, and also yeasts. Certain groups have never been studied in Egypt, such as Trichomycetes and black yeasts. By screening available sources of information, it was possible to delineate 2281 taxa belonging to 755 genera of fungi, including 57 myxomycete species as known from Egypt. Only 105 taxa new to science have been described from Egypt, one belonging to Chytridiomycota, 47 to Ascomycota, 55 to anamorphic fungi and one to Basidiomycota.
