The exsiccata 'Dupla Graecensia Lichenum (numbers 1291– 1330)' comprises 40 collections (271 specimens) of lichen duplicates (including the two non-lichenised fungi Mycocalicium subtile and Zythia resinae) from the following 10 countries: Artsakh (= Nagorno-Karabakh Republic, Province Martakert), Australia (state of New South Wales), Austria (states of Carinthia, Salzburg, Styria, and Upper Austria), Czech Republic (Jihočeský kraj [=Southern Bohemia]), Greece (Karpathos Island), Italy (region of Friuli-Venezia Giulia), Portugal (Madeira Island), Slovenia (Primorska), Spain (Canary Islands), Switzerland (canton of Bern). TLC-investigations were carried out for 15 species. Apothecia of Letharia vulpina have been shown to contain relatively high amounts of norstictic acid. Apothecia of Zythia resinae contain - beside a reddish-orange pigment - several depside/depsidone like compounds in high concentration.
