- Uncovering fungal diversity in mangroves: new records, ecological insights, and phylogenetic analysis of from Tarout Island, Saudi Arabia. Gaafar, Abdel-Rhman Z Elzein, Abdalla Khalaf, Sameh M H Hodhod, Mohamed S This study investigated the diversity and ecological patterns of marine fungi associated with decayed wood in the mangrove ecosystems of Tarout Island, Saudi Arabia. A total of 17 fungal species were isolated from four distinct mangrove stands that varied in vegetation density and environmental characteristics. These included ten teleomorphic ascomycetes and seven anamorphic fungi. Notably, 15 species were recorded for the first time from Tarout Island, and 13 species represent new records for the marine mycobiota of Saudi Arabia. was the most frequently encountered species, accounting for 30.07% of total isolates. Morphological identification was supported by scanning electron microscopy (SEM), revealing characteristic features such as erumpent ascomata and rough-walled ascospores. Molecular identification was conducted using large subunit (LSU) and small subunit (SSU) rDNA sequencing, and phylogenetic analysis confirmed the placement of within the family Ascocylindraceae. Environmental data collected from each stand revealed significant correlations between fungal diversity and key abiotic factors. Species richness showed a strong positive correlation with sediment nitrogen concentration (r = 0.72,
