This is a key to all species of Flavoparmelia and Flavopunctelia-species known to occur in Italy (Nimis 2016).
Flavoparmelia Hale This genus, with c. 32 species, includes yellow-green foliose lichens characterised by broad rounded lobes, non-ciliate margins, a pored epicortex, bifusiform or fusiform conidia, a cortex containing usnic acid, and cell-walls composed of isolichenan (Hale 1986). The genus has a worldwide distribution with the highest diversity in temperate and subtropical areas. For further details on its systematic position see Crespo & al. (2010).
Flavopunctelia (Krog) Hale This genus is a segregate of Punctelia based on differences in conidial morphology and chemistry (Hale 1984). Molecular studies confirm the distinction of these two groups with roundish pseudocyphellae at generic level (Thell & al. 2005). The genus consists of c. 5 species and has its speciation centre in Europe, Africa and South America. It is characterised by broad, yellow-green lobes with punctiform pseudocyphellae on the upper surface, bifusiform conidia, and the presence of usnic acid.
