Water pollution by heavy metals poses a growing threat to ecosystems and human health. Bioremediation using fungi offers a promising solution due to their tolerance and absorption capabilities. This study aimed to isolate and identify cadmium-tolerant fungi from the Iloilo River, a potentially polluted river in Iloilo City, Philippines using morpho-phylogenetic analysis. Water and sediment samples were collected, and fungi were isolated by serial dilution on PDA plates supplemented with cadmium ions [Cd(II)] (25 ppm). Isolates were further tested for tolerance to varying cadmium concentrations (50 and 100 ppm). Nine fungal species were identified, including three ascomycetous taxa (Pseudopestalotiopsis elaeidis, Peroneutypa scoparia, Diaporthe sp.) and six basidiomycetous taxa (Cerrena sp., Irpex laceratus, Phlebia sp., Pyrrhoderma noxium, Schizophyllum commune, Trichosporon asahii). The majority of the isolates originated from sediment samples. Morphological illustrations, descriptions, and taxonomic notes are provided for each taxon. These findings provide insight into the fungal diversity of the Iloilo River and their tolerance to cadmium.
