Erik Acharius (1757-1819) was Linnaeus's last student and the founder of modern systematic lichenology. Before his death in 2014, David Galloway found Acharius's personal, interleaved copy his book Lichenographiae suecicae Prodromus (1799) in the Manuscripts Department of the university library in Uppsala. It is a handsome volume, with a particularly luscious hand-painted frontispiece plate drawn and coloured by Acharius himself and with many hand-written changes, additions and lists. Clearly it was the working model for his later book, Methodus, and as such is a volume of considerable historical and taxonomic interest.
This work has now been digitised, a project initiated by David Galloway and completed as a fitting tribute to him as well as to Acharius. It can be viewed online by following this link to the Alvin portal.
The project was funded mainly by Uppsala University Library, the British Lichen Society and the Linnean Society of London.
