ResumoThe genus Graphis sensu Staiger is treated as a further contribution to the TICOLICHEN biodiversity inventory in Costa Rica. Graphis s.str. is the largest tropical lichen genus, with more than 300 accepted species worldwide, and also the largest in Costa Rica, with a total of 115 species recognized in this work. The following 25 species are described as new: Graphis altamirensis Sipman & Lücking sp. nov., G. argentata Lücking & Umaña sp. nov., G. bettinae Lücking, Umaña, Chaves & Sipman sp. nov., G. duplicatoinspersa Lücking sp. nov., G. firferi Lücking sp. nov., G. flavoaltamirensis Sipman & Lücking sp. nov., G. flavominiata Moncada & Lücking sp. nov., G. fournierii Lizano & Lücking sp. nov., G. gomezii Lücking, Will-Wolf & Umaña, G. gregmuelleri Sipman & Lücking, sp. nov., G. hypocrellina Lücking & Chaves sp. nov., G. inspersostictica Sipman & Lücking sp. nov., G. litoralis Lücking, Sipman & Chaves sp. nov., G. mirabilis Lücking, Sipman, Umaña & Chaves sp. nov., G. nudaeformis Lücking sp. nov., G. oryzaecarpa Lücking sp. nov., G. paradisserpens Sipman & Lücking sp. nov., G. paraserpens Lizano & Lücking sp. nov., G. pittieri Lücking, Umaña, Sipman & Chaves sp. nov., G. pseudocinerea Lücking & Umaña sp. nov., G. pseudoserpens Chaves & Lücking sp. nov., G. subflexibilis Lücking & Chaves sp. nov., G. subruiziana Sipman, Chaves & Lücking sp. nov., G. subturgidula Lücking & Sipman sp. nov., and G. tenoriensis Chaves & Lücking sp. nov. Graphis immersoides Lücking, nom. nov. [Bas. Graphina immersa Müll. Arg.; non Graphis immersa Fink], Graphis subchrysocarpa Lücking, nom. nov. [Bas.: Phaeographina ochracea C. W. Dodge; non Graphis ochracea Hepp], and Graphis submarginata Lücking, nom. nov. [Bas. Graphis marginata G. Mey. & Flot.; non Graphis marginata Raddi] are introduced as replacement names. Furthermore, 17 new combinations are proposed: G. bipartita (Müll. Arg.) Lücking, comb. nov., G. chondroplaca (Redinger) Lücking comb. et stat. nov., G. consanguinea (Müll. Arg.) Lücking, comb. nov., G. dichotoma (Müll. Arg.) Lücking, comb. nov., G. granulosa (Müll. Arg.) Lücking comb. nov., G. insulana (Fée) Lücking & Sipman, comb. nov., G. lutea (Chevall.) Aptroot, comb. nov., G. multisulcata (Müll. Arg.) Lücking & Chaves comb. nov., G. myrtacea (Müll. Arg.) Lücking, comb. nov., G. nuda (H. Magn.) Staiger & Lücking, comb. nov., G. plurispora (Redinger) Lücking & Chaves, comb. nov., G. puiggarii (Müll. Arg.) Lücking, comb. nov., G. rhizocola (Fée) Lücking & Chaves, comb. nov. [syn. G. anguilliformis Taylor; G. serpens Fée], G. subcontorta (Müll. Arg.) Lücking & Chaves, comb. nov., G. subhiascens (Müll. Arg.) Lücking comb. nov., G. xylophaga (R. C. Harris) Lücking, comb. nov., and Hemithecium plicosum (Meissn.) Lücking & Aptroot, comb. nov. [syn. Graphina malmei Redinger].The new name Pallidogramme Staiger, Kalb & Lücking, nom. nov. is introduced for Leucogramma A. Massal. [nom. illeg.; = Hemithecium subgen. Leucogramma Staiger], comprising a group of three species formerly included in Hemithecium Pallidogramme chapadana (Redinger) Staiger, Kalb & Lücking, comb. nov., P. chlorocarpoides (Nyl.) Staiger, Kalb & Lücking, comb. nov., and P. chrysenteron (Mont.) Staiger, Kalb & Lücking, comb. nov.More than 600 types of Graphidaceae suspected to represent species of Graphis s.str. were examined for this study, and notes on type material are given when appropriate. Also, the names previously reported for Costa Rica by the Swiss lichenologist Müller Argoviensis in 1891 and 1893 were checked when possible, and 175 unpublished collections from Costa Rica housed at the Farlow Herbarium (fh) of Harvard University and collected and identified by Carroll William Dodge and colleagues and students were revised.A key is presented to all species, including an image-based identification guide, and diagnostic characters in the genus Graphis are briefly discussed and illustrated. Diagnoses and remarks are given for all species treated here, as are more detailed
