中国海南文字衣科(子囊菌门,厚顶盘目)的一个新种和一个新记录种OA
A new species and a new Chinese record of Graphidaceae(Ostropales,Lichenized Ascomycota)from Hainan,tropical China
基于形态学、化学特征及分子系统发育学证据,本研究报道了 2 个中国地衣新记录属:金氏衣属 Gintarasia 和星缘衣属 Asteristion,其中包括 1 个新种——假裂金氏衣 G.pseudochapsa 和1 个新记录种——杯星缘衣A.cupulare,标本采自中国海南省.基于 ITS、nuLSU 及 mtSSU 序列构建联合数据集,采用最大似然法与贝叶斯推断进行系统发育分析;地衣特征化合物采用薄层色谱法检测.假裂金氏衣的主要特征为:地衣体灰绿色;子囊盘为不规则圆形至不规则线形,盘面肉色、无粉霜;子囊孢子非淀粉质;地衣体未检出地衣特征化合物.杯星缘衣的特征为:地衣体黄绿色;子囊果聚生,盘面肉色并具白色粉霜,具双层盘缘;果壳未炭化.本文提供了相关分类单元的详细形态描述、图版,并与近缘种进行了比较和讨论.
Based on morphological,chemical,and phylogenetic evidence,two lichen genera,Gintarasia and Asteristion,are reported for the first time from Hainan Province,China,together with a new species,G.pseudochapsa,and a new Chinese record,A.cupulare.Phylogenetic relationships were inferred from combined ITS,nuLSU and mtSSU sequence data using maximum likelihood(RAxML)and Bayesian analyses.The characteristic lichen compounds were analyzed by thin-layer chromatography(TLC).G.pseudochapsa is characterized by its gray-green thallus,irregularly rounded to elongate apothecia with a flesh-colored,epruinose disc,non-amyloid ascospores and the absence of the lichen substances.A.cupulare is characterized by a yellowish-green thallus,aggregate apothecia,a flesh-colored disc covered by white pruina,a double margin and a non-carbonized excipulum.Detailed descriptions,photographs and comparisons with similar taxa are provided.
