Not a lot of Graphidaceae in my area, but very large number elsewhere, e.g. from data.fs.usda.gov/research/pubs/iitf/ja_iitf_2014_Lucking0...:

 

Recent studies of the global diversity of the lichenized fungal family Graphidaceae suggest that there are a large number

of species remaining to be discovered. No less than 640 species have been described since 2002, including 175 new

species introduced in a collaborative global effort in a single issue in this journal. These findings suggest that the largest

family of tropical crustose lichens may have an even higher number of species than Parmeliaceae.

 

Our approach resulted in a prediction of

4,330 species of Graphidaceae, including approximately 3,500 (sub-)tropical species in the core subfamilies

Fissurinoideae, Graphidoideae, Redonographoideae, plus 125 species restricted to extratropical regions (outside the zone

between 30° northern and 30° southern latitude) and 700 species in subfamily Gomphilloideae. Currently, nearly 2,500

species are known in the family, including species not yet formally described. Thus, our model suggests that even after

describing 175 species in this issue and with another approximately 140 awaiting publication, the number of species still

to be discovered and described is more than 1,800, and much work remains to be done to close this substantial gap.

Based on our approach, we predict that most of this undiscovered diversity is to be found in Mexico, the northern Andean

region, the eastern Amazon and central and southern Brazil, tropical West Africa, continental Southeast Asia, Indonesia,

and Papua New Guinea
