Fungi are organisms that enrich the diversity of living things in the plant world. Macroscopic fungi significantly affect the forest food web, the survival or germination of saplings, tree growth, and the overall health of the forest. Ganoderma has been widely cultivated in various countries due to its benefits as a medicine which is known to have the ability to treat hypertension, hyperglycemia, acute bronchitis, hepatitis, leukopenia, and arteriosclerosis. Research on mushrooms is still very minimally documented, so this research needs to be done. This study aims to identify the types of macroscopic fungi of the ganodermataceae that exist in Martelu Purba Nature Reserve. This study uses a direct survey method in the field. This method can be done by exploring in an area. Based on the research results, 6 types of macroscopic fungi from the Ganoderma family were obtained, namely Amauroderma rude, Cymatoderma elegans, Ganoderma applanatum, Ganoderma adspersum, Ganoderma pfeifferi, and Ganoderma boninense. The six types of mushrooms come from 3 genera, namely Amauroderma, Cymatoderma, and Ganoderma. Each type has different morphological characteristics which are the basis for distinguishing them. The potential utilization of Ganoderma has now been widely developed in the medical world
