The present study was conducted to assess as well as monitor the status of macro-basidiomycetes in terms of species richness, abundance and distribution at Cagayan State University Lal-lo. It sought to profile the macro-basidiomycetes and looked into the ecological factors affecting their density and distribution. The study employed the Descriptive Classification Survey (Colmerin) design and quadrant method in field sampling. Opportunistic method for macro-basidiomycetes sampling was also used during the survey on the months of July to October 2017. Field sampling of macro-basidiomycetes resulted to the identification of five orders, 17 genera and 20 species with a total of 34 individuals. Majority of the basidiomycetes belonged to Order Polyporales. One species, a wood decay macrofungus, remained unidentified. Results showed that Schizophyllum commune (Fr.) (a) has the highest population density, while Ganoderma pfeifferi (Bres) has the lowest. In terms of population distribution, only six species were most distributed, and five species, including the unknown species, were least distributed. Correlation analysis showed that amount of rainfall, soil moisture and air moisture had positive effects on the density and distribution of some macro-basidiomycetes, while elevated soil and air temperature reduced the density and distribution of these species. In contrast, an increase in air and soil temperatures made the population of Volvariella volvacea to be more abundant and more dispersed. Results of this research shall be an important contribution in the creation of conservation actions and policies for strengthening the biodiversity conservation, especially of the country’s mycoflora.
