Some mushroom-eating slugs may be important – if slow – dispersal vehicles for fungal spores, which the animals spread through their faeces.
The languid molluscs deliver payloads of spores from a wide range of forest fungi, including honey (Armillaria) and rustgill (Gymnopilus) mushrooms, to microhabitats that are perfect for new fungal colonies.
