A revision of Leptogium ( Collemataceae , lichenized Ascomycota) from Antarctica with a key to species
Abstract With more than 180 known species, Leptogium has its greatest richness in tropical regions. Only three species have so far been reported from Antarctica but extensive surveys in the Antarctic Maritime Islands have shown that this is an underestimate. Leptogium antarcticum (non-isidiate, with...
