In the framework of continuing studies on the Graphidaceae in China, the status of all taxa traditionally assigned to the genus Graphina reported from China are resolved in the present paper. Five new combinations are made, namely Diorygma isabellinum (Zahlbr.) Z.F. Jia & Lücking, comb. nov., Fissurina adscribens (Nyl.) Z.F. Jia & Lücking, comb. nov., Graphis lecanactiformis (Zahlbr.) Z.F. Jia & Lücking, comb. nov., Phaeographis haloniata (Zahlbr.) Z.F. Jia & Lücking, comb. nov. and Platygramme taiwanensis (J.C. Wei) Z.F. Jia & Lucking, comb. nov. Five new synonymies were found: Graphina olivascens Zahlbr. (= Fissurina adscribens), Graphina plumbicolor Zahlbr. (= Phaeographis haloniata), Graphina roridula Zahlbr. and its variety platypoda Zahlbr. [= Diorygma pachygraphum (Nyl.) Kalb, Staiger & Elix], and Graphina taiwanensis f. obscurata J.C. Wei (= Platygramme taiwanensis). [ABSTRACT FROM AUTHOR]

As part of ongoing studies of the lichen family Graphidaceae in China, the status of all taxa traditionally assigned to the genus Phaeographina reported from China is resolved in the present paper. Five new combinations are proposed: Phaeographis pleiospora (Zahlbr.) Z.F. Jia & Lücking, comb. nov., Platygramme elaeoplaca (Zahlbr.) Z.F. Jia & Lücking, comb. nov., Platythecium maximum (Groenh.) Z.F. Jia & Lücking, comb. nov., P. pyrrhochroa (Mont. & Bosch) Z.F. Jia & Lücking, comb. nov., and Sarcographina heterospora (Nyl.) Z.F. Jia & Lücking, comb. nov. Six new synonyms are established: Phaeographina callospora Zahlbr. [= Diorygma hieroglyphicum (Pers.) Staiger & Kalb], P. fukiensis Zahlbr. [= Pallidogramme chrysenteron (Mont.) Staiger, Kalb & Lücking], P. fukiensis var. substriata Zahlbr. [= Pallidogramme chrysenteron (Mont.) Staiger, Kalb & Lücking], P. granulans Zahlbr. [= Platygramme platyloma (Müll. Arg.) M. Nakan. & Kashiw.], P. pluvisilvarum Zahlbr. [= Graphis alpestris (Zahlbr.) Staiger], and P. valida Zahlbr. [= Thecographa prosiliens (Mont. & Bosch) A. Massal.]. Two additional synonyms are reported: Phaeographina subrigida (Nyl.) Zahlbr. is synonymized under Platygramme platyloma (Müll. Arg.) M. Nakan. & Kashiw., and Platythecium dimorphodes (Nyl.) Staiger under Platythecium pyrrhochroum (Mont. & Bosch) Z.F. Jia & Lücking. [ABSTRACT FROM AUTHOR]

We studied the genus Chapsa in China based on morphological characteristics, chemical traits and molecular phylogenetic analysis. One species new to science (C. murioelongata M.Z. Dou & M. Li) and two records new to China were found (C. wolseleyana Weerakoon, Lumbsch & Lücking and C. niveocarpa Mangold). Chapsa murioelongata sp. nov. is characterised by its lobed thalline margin, orange discs with white pruina, clear hymenium, and submuriform and long ascospores. Chapsa wolseleyana was recombined into Astrochapsa based on phenotypic traits. Sequences of this species are for the first time reported here and phylogenetic analyses of three loci (mtSSU, ITS and nuLSU) supported the position of this species within Chapsa. A key for the Chapsa species known in China is provided. [ABSTRACT FROM AUTHOR]
