This research examines two species of mushrooms found in the Dominican Republic, expanding our understanding of fungal diversity in the Caribbean region. The study combines traditional morphological analysis with modern DNA techniques to better understand these species’ relationships and distribution. Impacts on everyday life: • Contributes to better understanding of fungal biodiversity in tropical regions • Helps mycologists and naturalists accurately identify these mushroom species • Advances our knowledge of fungal evolution and distribution patterns • Provides baseline data for future conservation efforts • Helps track potential changes in species distribution due to climate change
