“…He identified five Penicillium species including P. digitatum and P. italicum as the dominants. Moubasher et al (1971) found that the mycobiota of soil under five varieties of citrus was not specific, but almost similar to that in other Egyptian cultivated soils. The basic components here were Aspergillus, Fusarium and Penicillium.…”

“…Aspergillus was already earlier reported as the dominant genus from soil under citrus trees (Naim 1967, Moubasher et al 1971. Species of section Nigri (the black aspergilli) are ubiquitous saprotrophs in soils around the world, particularly in tropical and subtropical regions (Raper & Fennell 1965, Moubasher 1993, Domsch et al 2007, Sharma et al 2011.…”

“…Soil fungi have been extensively studied in Egypt by Moubasher and his collaborators and several other investigators (Sabet 1935, Ragab 1956, Besada & Yusuf 1968a, 1968b, Moubasher & Moustafa 1970, Moubasher & El-Dohlob 1970, Salama et al 1971, Moubasher & Mazen 1972, Ali et al 1975, Moubasher & Abdel-Hafez 1978a, 1978b, Moubasher 1993, 2010, Moubasher et al 1971, 1985. During this period, extensive surveys were performed in the Assiut University laboratory and in different environments in Egypt.…”

An extensive survey of soil mycobiota on citrus and grapevine plantations in Sahel-Saleem City, Assiut Governorate, Egypt was carried out using the dilution-plate method and 2 isolation media at 25°C. Sixty-four genera and 195 species of filamentous fungi and 10 genera and 13 species of yeasts were recovered. A higher diversity (number of genera and species) and gross total counts were recovered from citrus than from grapevine soil. The peak of filamentous fungi recovered from both soils was found to be in February. Aspergillus (45 species) was the most dominant genus; A. ochraceus predominated in citrus plantations, while A. niger and A. aculeatus in grapevine. The Penicillium count came second after Aspergillus in citrus (23 species) and after Aspergillus and Fusarium in grapevine (11 species). Penicillium citrinum, P. ochrochloron and P. olsonii were more common in citrus plantations, but they were replaced by P. oxalicum in grapevine soil. Fusarium (19 species) was represented in 88.9-100% of both soils on both media; F. solani predominated in both soils, while F. incarnatum came next in citrus, and F. babinda and F. oxysporum in grapevine. Humicola (3 species) with the dominant H. fuscoatra was recorded in 61.1-83.3% of soil of both plantations, while Talaromyces (with T. purpureogenus followed by T. pinophilus being the most common) was recorded in 83.3-100% on DRBC and 38.9-50% on DYM from the soil of plantations of both crops. Volutella (5 species) was common in citrus but missing from grapevine soil. The present study reveals that hyaline fungi predominated over dark-coloured ones. Yeasts comprised only minor proportions in both soils (maximum 0.5%). They showed their peak in the soil of citrus plantations in April and in grapevine in February. All species were recovered in one or two samples only. Diutina catenulata, Debaryomyces hansenii, Galactomyces (3 species), Hanseniaspora occidentalis, Kluyveromyces marxianus, Meyerozyma caribbica, and Schwanniomyces pseudopolymorphus were encountered in citrus only, while Cryptococcus laurentii, Pichia kudriavzevii, Meyerozyma guilliermondii and Rhodotorula sp. in grapevine only. Physiological and growth characteristics were obtained for most of the recovered yeasts.

“…Alternaria alternata is another very common fungus found in the phylloplane of several plants (e.g. KAMAL and SINGH 1970, MOUBASHER et al 1971, MISHRA and DICKINSON 1981, ANDREWS et al 1987, ANDREWS and HARRIS 2000. Cladosporium sphaerospermum, a very frequent fungal specie in our study, has been found less frequently in the phylloplane of other plants (DOMSCH et al 1980, ALHUBAISHI andABDEL-KADER 1991).…”

“…By focusing on fungi, leaf surfaces are open to colonization by members of several genera of saprophytic and pathogenic fungi. In Egypt, many investigations have been done on phyllosphere and phylloplane fungi of some cultivated plants; air fungal spore over these plants have been also studied (MOUBASHER et al 1971;MAZAN & GEHAN, M. SHABAN 1983;ABDEL-GAWAD 1984;MAZEN et al 1985;ABDEL-HAFEZ et al 1990, 1995BAGY & HEMIDA 1992). However, a few studies have been concentrated on leaf surface and pollen grains of some Egyptian wild plants (EL-NAGGAR et al 1993;ABDEL-HAFEZ & EL-NAGGAR 2001;EL-NAGGAR & ABDEL-HAFEZ 2003).…”

Leaves of two wild species of the flora of Egypt: Calotropis procera (Ait.) Ait., Asclepiadaceae and Chrozophora plicata (Vahl) A.Juss. ex Spreng., Euphorbiaceae have been studied morphologically and mycologically, in addtion to air borne fungi. Fifty five species and two varieties belonging to 26 genera of phyllosphere and phylloplane fungi were isolated from both plant species on glucose‐ and cellulose‐agar media. Mycological analysis was done monthly over six months (July to December, 2003). Alternaria alternata, Aspergillus fumigatus, A. flavus and A. niger were the basic fungal species found on leaf surfaces. Phylloplane of C. plicata caught specifically Chaetomium globosum, C. spirale, Cochliobolus lunatus, Drechslera halodes, Fusarium incarnatum, F. oxysporum, Memnoniella echinata and Papulaspora sepedonioides.The total counts of phyllosphere fungi of C. plicata were nearly twice as much as those of C. procera regardless medium's type.Forty species and one variety belonging to 22 genera of air borne fungi were recovered all over the experimental period (six months). Alternaria, Aspergillus, Cladosporium and Penicillium were the most frequently isolated species. The presented results revealed that, leaf shape and density (hair density and type) may be the most important factors of the biodiversity of the fungal species on the studied taxa.
