The soils of Mexico City (CDMX) are heterogeneous, compact, with an alkaline pH, and with low microbiological diversity. In this context, the objective of the present study was to explore the diversity of filamentous fungi in Canarian palm soils with contrasting health conditions during the dry and rainy season 2022. 55 Canary Island palms with different health categories were sampled. From each one, soil was collected from two concentric rings and samples composed of each ring and each palm were formed, for which the pH and electrical conductivity were first determined. To know their fungal populations, the soil dilution technique in PDA-TS (potato-dextrose-agar-tergitol-streptomycin) culture medium was used. Identification was based on cultural and morphological characteristics. In the soils of the study area, a richness of seven fungal species was found, Aspergillus niger was the most...
