Alan W. Archer is a mycologist and taxonomist. He is currently an honorary research associate at Royal Botanic Gardens Sydney. He uses chemotaxonomy as well as morphological features in taxonomy and to devise keys, most recently for the genus Pertusaria in the Australasia region.
Allographa leptospora is a species of script lichen in the family Graphidaceae. The lichen was first formally described in 1921 by Finnish lichenologist Edvard August Vainio as Graphis leptospora. The type specimen was collected in 1904 by German botanist Carl Curt Hosseus on Doi Suthep, where it was found growing on tree bark. Hosseus sent this and other lichens collected from Thailand to Vainio for identification. Robert Lücking and Klaus Kalb transferred it to the genus Allographa in 2018. In 2016, the lichen was reported from the Sintra Mountains, Portugal, which was its first documented occurrence in Europe.

The specific epithet lichexanthoimmersa refers both to the presence of lichexanthone as a secondary chemical, and the apothecia, which are immersed in the thallus. The lichen also contains norstictic acid.
