The lichens and allied fungi of Mount Mitchell State Park, North Carolina: a first checklist with comprehensive keys and comparison to historical data

A total of 171 species of lichens and allied fungi are reported from the spruce-fir forests of Mount Mitchell State Park, in the Black Mountains of North Carolina, based on both historical and modern records. Comparison of the modern baseline with the historical macrolichen baseline generated in the 1970s revealed potential losses of high-elevation southern Appalachian endemics (2 species), cyanolichens (5 species), species typical of exposed rock outcrops (1 species), and widespread species typical of hardwood substrates at high elevations (8 species). In addition to a checklist and summary of lichen biodiversity, dichotomous keys are provided that include all reported species.

本研究基于历史与现代记录，对北卡罗来纳州布莱克山脉密契尔山州立公园的云杉冷杉林展开调查，共记录到171种地衣及其近缘真菌。将本次现代调查本底与1970年代构建的历史大型地衣（macrolichen）本底进行比对后发现，该区域存在潜在的物种丧失：包括2种阿巴拉契亚南部高海拔特有种、5种蓝藻地衣（cyanolichens）、1种典型裸露岩崖生境物种，以及8种高海拔阔叶树基物广布物种。本研究除提供地衣生物多样性名录与综述外，还为所有记录物种编制了二歧分类检索表（dichotomous keys）。
