Graphidaceae is the second largest family of lichenized fungi, after Parmeliaceae, with 2100 species (Rivas Plata et al. 2012; Lücking et al. 2014; Lumbsch and Lücking 2015). The family is chiefly tropical, with a few taxa occurring in extratropical regions. After a thorough phylogenetic revision, the family now also includes the previously separate family Thelotremataceae and comprises 77 genera, now excluding the separate family Gomphillaceae which had previously also been synonymized with Graphidaceae (Lumbsch and Lücking 2015). Lücking et al. (2014) predicted that the
family might contain another 1800 undescribed species and 175 new species were recently described in a single, compiled work (Sohrabi et al. 2014). Here we described two further new species based on recent molecular phylogenetic analyses (Rivas Plata et al. 2013).
