- A high frequency of hypogeous fungi was detected in Sus scrofa feces.
- Symbiotroph taxa such as Hysterangium and Melanogaster were the most frequent.
- Native and introduced hypogeous fungi are being dispersed by Sus scrofa.
Fleshy hypogeous fungi produce scents that enable mycophagous mammals and invertebrates to locate them and disperse their spores. The European wild boar (Sus scrofa) was introduced in central Argentina in 1900s and later expanded into Patagonia. Here, we determined the diversity and abundance of fungal taxa, and the frequency of hypogeous fungal spores in wild boar feces in Patagonia. We collected fecal samples on Isla Victoria, Nahuel Huapi National Park, and identified fungi using microscope and DNA metabarcoding of ITS2 rDNA. Hypogeous fungal spores occurred in almost all fecal samples. The most abundant species belonged to the genera Hysterangium, Melanogaster, Radiigera and Gautieria. In addition to the symbiotrophic hypogeous taxa, we also identified numerous pathotrophic and saprotrophic taxa. Not only diverse native hypogeous fungi, but also introduced ones are part of the diet of the wild boar in forests of Patagonia. If viable, introduced fungi are being dispersed as far as 2.5Â km from the nearest plantation, highlighting how the introduced wild boar might alter the local distribution and composition of fungal communities.
