This study employed the descriptive research method and purposive sampling technique to conduct a comprehensive analysis of macrofungi species. Its primary objectives were to gather and classify macrofungi species, examine environmental factors, assess their economic significance, and identify human activities that affect macrofungi in the study area. Samples were collected from different barangays in Lavezares, Northern Samar, Philippines, each representing a distinct ecosystem. A total of forty-five (45) species were gathered, with only three (3) found to be edible, making them economically valuable as human food. The sampling sites, which varied in elevation from plain to moderately elevated terrain, experienced warm air temperatures ranging from 28.3oC to 30.3oC, along with humidity levels between 72.5% and 82%. The soil pH in the area ranged from 7.1 to 7.3, indicating a slightly alkaline nature. Although rainfall was observed during the sampling period, macrofungi predominantly appeared on sunny days following the rain. The study sites exhibited similar vegetation, characterized by coconut plantations, grasslands, and shrubs, where macrofungi were primarily found on coconut and banana trunks, decaying logs, and other decomposing organic matter. However, the researchers noted the presence of anthropogenic activities such as swidden farming (slash-and-burn or "kaingin"), deforestation, and conversion of land to non-agricultural purposes within the study sites. The results indicated a diverse range of macrofungi species in the study area, highlighting the crucial role of environmental conditions in their growth and development. While the impact of anthropogenic activities on macrofungi appeared to be minimal, there is still a need to protect and conserve these organisms. Consequently, the researchers recommend conducting further studies on macrofungi, particularly focusing on their economic relevance and potential as sources of secondary metabolites or constituents with potential medical applications.
