“…The genus Monocillium is the asexual state of Niesslia (Ascomycota). Niesslia is a weak cellulose decomposer that has been found in salt marshes (Moustafa and Sharkas, ), suggesting that some species have high salinity tolerance. In below‐grade foundation walls, alkaline water can filtrate through concrete and moisten building paper.…”

Below-grade foundation walls are often exposed to excessive moisture by water infiltration, condensation, leakage, or lack of ventilation. Microbial growth in these structures depends largely on environmental factors, elapsed time, and the type of building materials and construction setup. The ecological preferences of Actinomycetes (Actinobacteria) and the molds Ascotricha chartarum, Myxotrichum chartarum (Ascomycota), Geomyces pannorum, and Monocillium sp. (Hyphomycetes) have been addressed based on analyses of 1764 samples collected in below-grade spaces during the period of 2001-2012. Our results show a significant correlation between these taxa and moist foundation walls as ecological niches. Substrate preference was the strongest predictor of taxa distribution within the wall, but the taxa's physiological needs, together with gradients of abiotic factors within the wall structure, also played a role. Our study describes for the first time how the wall environment affects microbial growth.

“…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. Aspergillus ochraceus has a wide distribution in soil in Egypt (Moubasher & Moustafa 1970, Moubasher & Abdel-Hafez 1978a, Moubasher et al 1985), Jordan (Moubasher et al 1977, 1981, Kuwait (Moustafa & Al-Musallam 1975, Moustafa & Sharkas 1982, Halwagy et al 1982, Qatar (Moubasher & Al-Subai 1987), Saudi Arabia (Abdel-Hafez 1981, 1982, Sudan (El-Amin & Abdalla 1980), and Syria (Abdel-Kader et al 1983).…”

“…Naim (1967) found that Cladosporium was one of the dominant genera isolated from soil under citrus trees. The common species C. cladosporioides was isolated from soil of Vigna sinensis, Egypt (Abdel-Kader et al 1983), soil at Wadi Bir-El-Ain, Eastern Desert, Egypt (Moubasher et al 1985), and soil in Jordan (Moubasher et al 1977, Mazen et al 1980), Kuwait (Moustafa & Al-Musallam 1975, Moustafa & Sharkas 1982, Halwagy et al 1982, Qatar (Moubasher & Al-Subai 1987), Saudi Arabia (Abdel-Hafez 1981, 1982, Abou-Heilah 1985, and Syria (Abdel-Hafez et al 1983). This species was one of the dominant soil colonisers in Northeastern India (Sharma et al 2011) and is the incitant of serious plant diseases, e.g.…”

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.

“…STOVER (1955) showed that Fusarium oxysporum survived in anaerobic submerged marsh soils and that species of Trichoderma, Aspergillus and Penicillium could tolerate the same conditions for at least 67 days. It was found that Aspergillus, Penicillium and Stachybotrys were the most common genera in mud-flats of Kuwait (EL-WAHID et al 1982 andSHARKAS 1982). The remaining terrestrial species had been previously isolated in varying numbers and frequencies from related habitats by several workers (e.g.…”
