Abstract

A new species, Lecanora darelensis sp. nov is described here from Darel Valley, Gilgit Baltistan, Pakistan. A comparative morpho-anatomical, chemical study and ITS-based molecular analyses confirmed the position of new species within the genus Lecanora. The new taxon is phylogenetically closely related to L. argopholis. The former can be distinguished from latter in having pale yellowish green upper surface (vs yellowish white), larger apothecial disc 0.5–1.5 mm (vs c. 1.2 mm), brown, plane to convex, pruinose to rarely epruinose apothecial disc (vs deep yellowish brown, plane or slightly concave, epruinose), taller epihymenium 25–35 µm (vs c. 20 µm), taller hymenium 110–150 µm (vs 70–75 µm), larger ascospores 14–18 × 5–8 µm (vs c. 12.7 × 7.3 µm), atranorin is detected by TLC (vs atranorin, epanorin, zeorin) and growing on calcareous rocks (vs rock surfaces, detritus, mosses, sloping siliceous and calcareous rocks, boulders, gravel).

巴基斯坦吉尔吉特-巴尔蒂斯坦 Darel 谷的 Lecanora darelensis，Lecanoraceae 的一个新种

本文描述了产自巴基斯坦吉尔吉特-巴尔蒂斯坦省达雷尔山谷的新种Lecanora darelensis sp.nov。比较形态解剖学、化学研究和基于 ITS 的分子分析证实了新种在 Lecanora 属中的位置。新分类群在系统发育上与 L. argopholis 关系密切。前者与后者的区别在于前者的上表面为淡黄绿色（vs 黄白色），皮孔盘较大，长 0.5-1.5 mm（vs 约 1.2 mm），皮孔盘为棕色，平面或凸面，具粉霜或很少具附着粉霜（vs 深黄褐色，平面或稍凹面，具附着粉霜），表膜较高，长 25-35 µm（vs 约 20 µm），膜片较高，长约 1.5 mm（vs 约 1.5 mm）。20 µm），较高的膜片 110-150 µm（vs 70-75 µm），较大的无孢子 14-18 × 5-8 µm（vs 约 12.7 × 7.3 µm），通过 TLC 检测到阿特拉诺林（vs atranorin、epanorin、zeorin），生长在石灰质岩石上（vs 岩石表面、碎屑、苔藓、倾斜的硅质和石灰质岩石、巨石、砾石）。
