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
A new species and a new Chinese record of Graphidaceae(Ostropales,Lichenized Ascomycota)from Hainan,tropical China
摘要
Abstract
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.关键词
