6); the lirellate genera in other clades Selleckchem CUDC-907 (Fissurinoideae, Thelotremateae) have always hyaline, predominantly non-amyloid (to weakly amyloid) ascospores. Allographa, Glyphis, Graphis, and Schistophoron are PRN1371 solubility dmso well-delimited, strongly supported monophyletic clades (Rivas Plata et al. 2011a), whereas the genera Diorygma and allies (Anomomorpha, Platythecium, Thalloloma) and Phaeographis and allies (all brown-spored lineages) require further phylogenetic studies.

The Graphis clade is genetically distinct from the clade including the remaining genera (Rivas Plata et al. 2011a). Ocellularieae Rivas Plata, Lücking and Lumbsch, trib. nov. MycoBank 563412 Tribus novum ad Graphidoideae in Graphidaceae pertinens. Ascomata rotundata vel rare elongata, immersa vel sessilia. Excipulum hyalinum vel carbonisatum. Hamathecium non-amyloideum et asci non-amyloidei. Tideglusib in vitro Ascospori transversaliter

septati vel muriformes, incolorati vel fusci, amyloidei vel non-amyloidei, lumina lenticulari vel rare rectangulari. Acidi lichenum variabili sed acidum psoromicum et acidum protocetraricum et adicum hypoprotocetraricum et cinchonarum frequentia. Type: Ocellularia G. Mey. Ascomata rounded to rarely elongate, immersed to sessile. Excipulum hyaline to carbonized, usually prosoplectenchymatous. Periphysoids absent. Columellar structures commonly present. Hamathecium and asci non-amyloid. this website Ascospores transversely septate to muriform, colorless to (grey-)brown, amyloid to non-amyloid, septa thickened but often reduced in muriform ascospores, lumina lens-shaped to rectangular. Secondary chemistry variable but psoromic, protocetraric and hypoprotocetraric acids and cinchonarum unknown predominant.

Genera included in tribe (11): Ampliotrema Kalb ex Kalb, Fibrillithecis Frisch, Gyrotrema Frisch, Leptotrema Mont. and Bosch, Melanotrema Frisch, Myriotrema Fée, Ocellularia G. Mey., Rhabdodiscus Vain., Reimnitzia Kalb, Redingeria Frisch, Stegobolus Mont. (Fig. 1). Tribe Ocellularieae is the second largest clade in the family with currently over 350 accepted species in twelve genera (Rivas Plata et al. 2011b) and a great deal of morphological variation (Fig. 7). It comprises two strongly supported clades, one including Leptotrema and Reimnitzia and a second one including all other genera. The latter clade includes several smaller and one large clade that corresponds chiefly to Ocellularia sensu Hale (1980).
