2006). Genera were delimited using a more detailed approach based on a series of partially correlated characters, such as excipular structure, ascospore type, thallus structure, and secondary chemistry. During the past decade, these results have been tested using molecular approaches, with a growing amount of sequence data available (Staiger 2002; Kalb et al. 2004; Lumbsch et al. 2004, 2008; Frisch et al. 2006; Staiger et al. 2006; Mangold et al. 2008; Baloch et al. 2010; Rivas Plata and Lumbsch 2011a, b; Rivas Plata et

selleck kinase inhibitor al. 2011a, b). As a result of these studies, the generic concepts were further refined, with over 50 genera currently accepted in Graphidaceae including the former Thelotremataceae. RG-7388 in vivo It was also shown that Graphidaceae and Thelotremataceae were non-monophyletic and that

Thelotremataceae is nested within Graphidaceae, where they form five major clades (Mangold et al. 2008; Rivas Plata and Lumbsch 2011a). In addition, two independent studies supported a further family, Gomphillaceae, as part of Graphidaceae (Baloch et al. 2010; Rivas Plata et al. 2011a). These results require substantial formal changes in the nomenclature and classification of Graphidaceae, which are proposed in this paper. Material and methods We summarized the findings of recent phylogenies (Staiger et al. 2006; Mangold et al. 2008; Baloch et al. 2010; Rivas Plata and Lumbsch 2011a, b; Rivas Plata et al. 2011a, b) to assemble a cartoon tree (Fig. 1) that depicts the major clades of the emended Graphidaceae and their relationships within http://www.selleck.co.jp/products/cobimetinib-gdc-0973-rg7420.html the family.

tree showing relationships between major clades (with the proposed subfamilies and tribes) of Graphidaceae. Numbers indicate approximate number of currently recognized species. Thick lines indicate clades with strong support. Columns to the right indicate previous Pevonedistat order placement of genera in either Graphidaceae or Thelotremataceae (left column: G, T), as well as placement of thelotremoid genera in Hale’s genera Myriotrema (M), Ocellularia (O), and Thelotrema (T); D = Diploschistes, N = Nadvornikia Descriptions of new species were assembled using standard methods of light microscopy and thin layer chromatography (Arup et al. 1993; Lumbsch 2002). Images were taken with a NIKON Coolpix 5400 digital camera mounted on a LEICA MS5 dissecting microscope and a JENOPTIC ProgRes C3 digital microscope camera mounted on an OLYMPUS SZX12 dissecting microscope.
