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.

Nobuko Tuno at Kanazawa University in Japan had been studying the potential for fungi to make use of animals as spore dispersers. But she didn’t think much about slugs in this role, since they …
