摘 要: 该文综合运用形态学、解剖学和化学等方法对山东大型地衣进行分类研究,发现了两个中国新记录种,即德氏蜂窝衣(Heppia despreauxii)和多孢小极衣(Lichinella myriospora)。德氏蜂窝衣隶属于蜂窝衣属(Heppia),生于光线充足且裸露的土壤上,主要识别特征为下皮层缺失、子实层IKI+蓝色;多孢小极衣隶属于小极衣属(Lichinella),生于干燥的钙质岩石上,主要识别特征为其子实层IKI+酒红色变为蓝色。该文对这两个中国新记录种进行了详细描述,与近似物种进行了对比讨论,并且提供了其地衣体、子囊盘及其解剖特征图片。同时,该文还补充报道了白棋盘蜂窝衣(Heppia solorinoides)的有性繁殖结构特征和数据。蜂窝衣属和小极衣属均为山东新记录属。以上研究结果为中国异极衣科(Lichinaceae)地衣研究提供基础资料。

Abstract:  Morphological, anatomical and chemical characters were used in this research. Two Lichinaceae species new to China, Heppia despreauxii and Lichinella myriospora, were discovered during a taxonomical study of the macrolichens from Shandong Province. Heppia despreauxii, belonging to the genus Heppia, grows on well-lit bare soil in open situations, and is characterized by its absence of lower cortex and hymenium IKI+ blue; Lichinella myriospora, belonging to the genus Lichinella, occurs on calcareous rock in arid sites, and is characterized by its hymenium IKI+ wine-red turning blue. Descriptions in detail, comments with similar species, and morphological photographs of these two species are provided. The materials of Heppia solorinoides, reported from China by other lichenologists, lack apothecia, and the morphological and anatomical characters of its apothecia are described according to the materials collected and examined by us. Both genera Heppia and Lichinella are reported for the first time from Shandong Province. All these results provide basic data information for the taxonomy of the family Lichinaceae.

山東省地处暖温带,属于温带季风气候区,分布有温带阔叶落叶林,主要分为鲁东、鲁中南山地丘陵地区和鲁西北平原区两种地形。山东东部为鲁东丘陵,具隶属崂山山脉的昆嵛山和崂山两座沿海高山,中部和南部为鲁中山地,主要有泰山、蒙山和沂山等构成的泰沂山脉。

近20年来,多位地衣学家对山东省地衣物种多样性进行了调查和标本采集工作,并报道了许多中国或山东省地衣新记录种,其中,包括山东省大型地衣共计29属98种(赵遵田等,1998,1999,2002;张峰等,1999;侯亚男等,2008;李颖等,2008;Sun et al., 2013; 任强和郑晓佳,2020)。2008年以前的文献主要以地衣物种名录的形式列出了该地区的物种,并没有对物种进行描述和与近似种进行对比讨论。……
