摘　　要：文章报道中国茶渍属地衣3个新记录种——亚异茶渍(Lecanora subravida Nyl.)、栎生茶渍(L.quercicola Coppins&P.James)和针叶茶渍(L.coniferarum Printzen),该3个物种均隶属于柳茶渍组(Lecanora saligna group)。该类群主要特征为,朽木生,地衣体龟裂状至疣状或完全不明显,子囊盘黄绿色至棕色或颜色多样,表面具轻微粉霜,主要化学次生代谢产物为松萝酸。本研究使用贝叶斯分析(BI)构建了基于2个基因位点(nrITS,mtSSU)系统发育树,分析了该3种在茶渍属中的进化位置。本研究还对每个种详细描述形态-解剖特征、分布及栖息地等情况,并提供了地衣体、子囊盘及子囊孢子的彩色图片。Three crustose lichen species of the genus Lecanora,Lecanora subravida Nyl.,L.quercicola Coppins&P.James,L.coniferarum Printzen are recorded for the first time for China.These belongs to the Lecanora saligna group.Species in the Lecanora saligna-group are characterized by a corticolous,having rimose-areolate to warts thallus or endophloedal thallus,yellowish-green to brown or variable in color,the apothecial disc is slightly pruinose,and usnic acid as a major secondary metabolite.Based on nrITS and mtSSU sequences,phylogenetic tree was constructed by Bayesian inference(BI)method to clarify position of the three species in Lecanora.Additionally,detailed morphological-anatomical descriptions,illustrations,distribution,habitat and color photos of those species are provided.
