In the current study, fifty-eight Ingoldain fungal species assignable to forty-one genera were recovered from two water bodies receiving the treated sewage and the effluents of oils and soaps factory at Assiut Governorate (Upper Egypt), of which Anguillospora, Amniculicola, Flagellospora, and Mycocentrospora were the most prevalent genera. The most widespread identified species were Anguillospora furtive, Amniculicola longissima and Flagellospora fusarioides. Forty-three species were identified for the first time in Egypt. The most Ingoldain taxa were estimated for El-Zinnar canal, with the highest recorded taxa in winter. Whereas, the highest dominance of Ingoldian fungi was estimated for the El-Ibrahimia canal. The highest Simpson and Shannon diversity indexes were estimated for El-Zinnar canal samples recording 0.9683 and 3.741, respectively. The poorest water sites with Ingoldian fungi were those exposed directly to either treated sewage or industrial effluents, with which relatively higher values of water conductivity, cations and anions. Water temperature was the main abiotic factor driving the seasonal occurrence of Ingoldian fungi. It is interesting to isolate some Ingoldian fungal species from the stressful water sites receiving the effluents which provide valuable insights regarding their adaptation, predictive and putative role as bioindicators and their potentiality in pollutants degradation, organic decomposition, and transformation of xenobiotic compounds.
在当前的研究中，从接收处理过的污水和油脂工厂废水的两个水体中回收了 58 种可分配到 41 属的 Ingoldain 真菌物种，其中 Anguillospora、Amniculicola、Flagellospora 和 Mycocentrospora 是最常见的属。最广泛鉴定的物种是 Anguillospora furtive、Amniculicola longissima 和 Flagellospora fusarioides。有 43 种是首次在埃及鉴定的。Ingoldain 类群估计在 El-Zinnar 运河中最多，冬季记录的类群最多。而 Ingoldian 真菌的最高优势度估计在 El-Ibrahimia 运河中。El-Zinnar 运河样本的 Simpson 和 Shannon 多样性指数最高，分别为 0.9683 和 3.741。暴露于处理过的污水或工业废水的 Ingoldain 真菌最差的水点，其水的电导率、阳离子和阴离子相对较高。水温是驱动 Ingoldian 真菌季节性出现的主要非生物因素。从接收废水的有压力的水点分离出一些 Ingoldain 真菌物种很有趣，这为它们的适应、预测和潜在的生物指示作用以及它们在污染物降解、有机分解和外来化合物转化方面的潜力提供了有价值的见解。
