In 1969 he was appointed professor and head of department in the School of Biological Sciences at the University of Exeter, where he remained until his retirement in 1990.

Contributions to mycology
Webster helped organise the first International Mycological Congress, which was held at Exeter University in September 1971. He acted as its secretary, with
G.C.Ainsworth as chairman of the organising committee and
C.T.Ingold as its president. The Exeter congress led directly to the formation of the

Webster also served two terms as president of the British Mycological Society, firstly in 1969, then again in its centenary year in 1996.
As an educator, John Webster's undergraduate teaching classes introduced many students to the world of fungi, some of whom went on to become leading mycologists or academics in their own right, including

His classic textbook book, ''Introduction to Fungi'' was first published in 1970, with every illustration drawn by him from live specimens. The book ran to three editions, the second appearing in 1979 and the third in 2007.
Webster's greatest contribution to the science of mycology was in determining the mechanism for fungal spore discharge in

Honours and recognition
In 1987 Webster was made a Corresponding Member of the Mycological Society of America. He served as the International Mycological Association's third president from 1983 to 1990, and was then made honorary president for life in 1990. In 1996 the association awarded him their Ainsworth Medal in recognition of his "extraordinary service to world mycology".
In 2011 the British Mycological Society conferred on John Webster their President's Award in recognition of his broad contributions to mycology and to the society over many decades.
