Abstract

In 2019, during May to September a unique lichen occurring on soil was collected from four different localities in Deosai National Park, Gilgit-Baltistan, Pakistan. Phylogenetic analysis of the nrDNA ITS and LSU regions revealed that it clustered within the genus Placidium. Further morpho-anatomical and chemical analyses proved its novelty, and it is here described as a new species under the name P. deosaiense. The distinguishing characters of this novel taxon are brown to blackish 2–7 mm wide squamules, undulating in the center, epruinose at margins, epinecral layer up to 70 lm, cylindrical asci with ellipsoid to narrowly ellipsoid ascospores and clavate to bacilliform pycnidiospores.

来自巴基斯坦吉尔吉特巴尔蒂斯坦Deosai国家公园的一种新型北极高山地衣

2019年5月至9月，在巴基斯坦吉尔吉特-巴尔蒂斯坦Deosai国家公园的四个不同地点采集到了一种独特的土壤地衣。对nrDNA ITS和LSU区域的系统发育分析表明，它聚集在Placidium属内。进一步的形态解剖和化学分析证明了它的新颖性，并将其描述为一个新种，名为P.deosaiense。这个新分类单元的显著特征是棕色到黑色的2–7毫米宽的鳞片，中心起伏，边缘具epruinose，内冠层高达70 lm，具有椭圆形到窄椭圆形子囊孢子和棒状到杆状pycnidiospores的圆柱形海鞘。
