We proposed Parmelia maculoides Gyeln. as a synonym of Punctelia stictica (Delise ex Duby) Krog;Physcia hosseana Gyeln. as a synonym of Physcia stellaris (L.) Nyl. and Teloschistes exilis (Michx.) Vain. f. inaequalis Gyeln. as a synonym of Teloschistes nodulifer (Nyl.) Hill- mann based on the study of the Argentinian type material of Kofarago-Gyelnik. We also confirmed the presence of Oropogon loxensis (syn. Bryopogon hosseusianus Gyeln.) in Central Argentina by comparing the type specimen with samples collected recently. Finally we excluded the presence of Parmotrema stuppeum (Taylor) Hale from Argentina.
