Cecil Terence Ingold CMG was "one of the most influential mycologists of the twentieth century". He was president of the British Mycological Society where he organised the first international congress of mycologists. An entire class of aquatic fungi within the Pleosporales, the Ingoldian fungi, were named after him, although recent DNA studies are changing the scientific names.

The British Mycological Society is a learned society established in 1896 to promote the study of fungi.
