Introduction: Arbuscular mycorrhizae, symbiotic associations between fungi and plant roots, play a fundamental role in the nutrition and survival of many forest species. The objective of the study was to morphologically identify the arbuscular mycorrhizae population based on the development stage of Retrophyllum rospigliosii (Pilg.) C.N. Page in the Huamantanga forest, Jaén, Peru. Materials and methods: Quantitative approach, descriptive type. Three soil and root sampling areas were selected in the sapling, latizal and fustal categories: area 1 (squirrel tail sector), area 2 (squirrel tail road sector) and area 3 (Nueva Jerusalén sector). Results: According to the statistical analysis (ANVA), the hypothesis of equal means is rejected, so there is a significant difference between the natural regeneration categories. Discussion: The results obtained in this study reveal a community of arbuscular mycorrhizal fungi (AMF) dominated by the genera Glomus, Entrophospora and Acaulospora, associated with Retrophyllum rospigliosii in the Huamantanga forest. Likewise, a diversity of morphospecies was identified with a total of 16 morphospecies distributed in the genera Acaulospora, Entrophospora and Glomus. Conclusions: The highest colonization was for saplings, in roots 93.0%, in soil 91.7%; followed by latizal, in roots 88.3%, in soil 89%; then by stem, in roots 86.7%, in soil 87.3%. The AMF associated with Retrophyllum rospigliosii (Pilg.) C.N. Page., identified are: Acaulospora 4 morphospecies, Entrophospora 5 morphospecies, and Glomus 7 morphospecies.
