Laundon specialized on rust fungi (then known as Urediniomycetes; now as Pucciniales). Rusts are considered among the most harmful pathogens to agriculture, horticulture and forestry. Rust fungi are major concerns and limiting factors for successful cultivation of agricultural and forest crops. White pine blister rust, wheat stem rust, soybean rust, and coffee rust are examples of notoriously damaging threats to crops. Laundon soon became well-known in the field for thorough, careful work on the class, first publishing new taxa in 1963.
In 1965 the Commonwealth Mycological Institute published Laundon’s book, The Generic Names of Uredinales. This was reviewed in the Transactions of the British Mycological Society:
“Nomenclature at best is a tedious business for many of us, but until a better system is invented the best we can do is to have a set of names whose basis is firmly established. Mr Laundon has done this service for the generic names of rusts nobly.”
Among Laundon’s most important contributions was a new system of spore terminology published in 1967 - this was controversial at the time but was generally accepted later.
In 1963 Laundon married Margaret Cox and they had three children. In 1965 they emigrated to New Zealand, where Laundon became mycologist at the Plant Health & Diagnostic Station at Levin, and continued to research the taxonomy and nomenclature of rusts. Laundon was an active member of the International Association for Plant Taxonomy and was on the Special Committee for Fungi and Lichens for a number of years.

Laundon was the first to realise there were two species involved when the poplar rusts were first found in New Zealand in 1972, a claim not verified until samples of the spores were examined with an electron microscope.
By 1977 Laundon had transitioned as Gillian. She was supported in this by her wife and children. She was initially involved in Hedesthia, the then major New Zealand trans group, but it was mainly oriented to transvestites. Gillian, using her wife’s surname, in 1976 set up Transformation, which was more focused on transsexual issues. Gillian and Margaret produced several information leaflets and fielded questions from transsexuals, interested public and professionals alike, seeking to aid and educate as many people and groups as they could.
She placed an announcement in the New and Notes section of the Taxon journal:
“Mr G. F. Laundon of the Plant Health & Diagnostic Station, Levin, New Zealand has changed sex as from the 22nd Jan. 1977 and is now known as Miss Gillian Laundon. She continues her work in plant pathology, mycology and nomenclature.”
Actually she had become Gillian Fiona Laundon, which enabled her to take advantage of the practice of Onomastic Occlusion, that is to continue to publish professionally as “G F Laundon”.
However at work some staff strongly opposed her using female toilets. She was restricted to only one toilet and threatened with disciplinary action if she used another. However she was supported by other colleagues including her controlling officer who wrote to the State Services Commission (SSC) on her behalf in order to suggest that guidelines be set up so that “transexuals be treated consistently in the public service”. She was supported by Leone Neil, also a Hedesthia member and public servant. By 1978 Laundon had won her case and was free to use whatever facility she pleased.
However, the SSC did not implement any guidelines, and discrimination was still rife in the public service. In 1979 Laundon wrote in support of a trans woman in another department who was to be subjected to a vote by her colleagues over whether she should be able to use the female toilets.
Over her career Laundon collected at least 211 specimens and identified 539 that are in formal herbaria or culture collections. The species Phoma laundoniae is named in her honour.
