中文摘要：
该文报道了文字衣科（Graphidaceae）地衣一广西新记录属——炭刺文衣属（Carbacanthographis）。该属主要特征是子囊盘面闭合,果壳炭化,盘唇具白色粉霜层,类缘丝具疣,子囊孢子砖壁型或横隔双透镜型,I-或微I＋。枯炭刺文衣,标本采自广西金秀圣堂山,该种特征是线盘明显、盘被两侧炭化、子囊孢子无色砖壁型、孢子大小（12.5-20）×（5-7.5）μm、地衣体含有水杨嗪酸。该属是中国稀有属,迄今仅有1种报道。该种首次在内陆自然环境中发现,这对于炭刺文衣属及其类群的区系研究、物种保护和利用具有很重要的意义。
英文摘要：
The lichen genus Carbacanthographis is reported as new to Guangxi,characterized by the closed disc,carbo nized exciple,labia covered with a distinct white pruinose layer,warty periphysoids,and I- or weakly I＋,muriform or trans-septate ascospores. The species C. marcescens is characterized by the conspicuous lirellae,the laterally carbonized exciple,the hyaline ascospores muriform with（ 12.5- 20） ×（ 5- 7.5） μm size,and the presence of salazinic acid. The specimens examined come from Mt. Shengtang,Jinxiu,Guangxi. So far,only one species reported in the rare genus from China. The species was firstly found in the natural environment and inland of Guangxi,China. Which is very important to the flora study,protection and using of the species resource.
