Data from: Lichen biodiversity and ecology in the San Bernardino and San Jacinto Mountains in southern California (U.S.A.)

San Bernardino National Forest in southern California encompasses two major mountain ranges, the San Bernardino Mountains and the San Jacinto Mountains. Here 414 taxa of lichenized fungi are reported from San Bernardino National Forest as a whole; 327 from the San Jacinto Mountains (including the Santa Rosa Mountains), and 289 from the San Bernardino Mountains. Two species new to science are described: Lecanora remota and Lecidea stratura. Two undescribed taxa of Bellemerea and Scytinium are reported, both currently under study. Five species are reported new for North America and California: Gloeoheppia rugosa, Lecanora formosa, Peccania cernohorskyi, P. corallina and Psorotichia vermiculata. Peccania cernohorskyi is also reported new for Canada (British Columbia). Eight species are reported new for California: Caloplaca diphasia, C. isidiigera, Peltigera extenuata, Rhizocarpon simillimum, Rinodina lobulata, R. terrestris, Sarcogyne squamosa, and Xylographa difformis. Lecidea xanthococcoides is recognized as a synonym of Lecanora cadubriae. The California endemic Lecidea kingmanii is reported as producing 4-0-demethylplanaic acid. Polysporina simplex is treated as Acarospora simplex and P. urceolata as A. urceolata. The new combination Acarospora gyrocarpa is proposed for Polysporina gyrocarpa.

加利福尼亚州南部的圣贝纳迪诺国家森林（San Bernardino National Forest）涵盖两大山脉——圣贝纳迪诺山脉与圣哈辛托山脉。本研究总计报道该森林全境共414个地衣型真菌（lichenized fungi）分类单元；其中圣哈辛托山脉（含圣罗莎山脉）记录有327个类群，圣贝纳迪诺山脉记录有289个类群。本文描述2个科学新种：近缘盘衣（Lecanora remota）与条纹鳞盘衣（Lecidea stratura）。另报道2个尚未正式发表的贝梅雷衣属（Bellemerea）与线叶衣属（Scytinium）类群，目前二者均处于研究阶段。另有5个物种为北美地区与加利福尼亚州的首次分布记录：皱孢胶盾衣（Gloeoheppia rugosa）、美丽盘衣（Lecanora formosa）、切尔诺霍尔斯基佩坎衣（Peccania cernohorskyi）、珊瑚状佩坎衣（P. corallina）以及蠕形微孢衣（Psorotichia vermiculata）。其中切尔诺霍尔斯基佩坎衣同时为加拿大不列颠哥伦比亚省的首次分布记录。另有8个物种为加利福尼亚州的首次分布记录：双型黄茶渍（Caloplaca diphasia）、具裂芽黄茶渍（C. isidiigera）、细裂皮叶衣（Peltigera extenuata）、相似黑盘衣（Rhizocarpon simillimum）、叶状黑星衣（Rinodina lobulata）、陆生黑星衣（R. terrestris）、鳞形盘菌衣（Sarcogyne squamosa）以及异形木盘衣（Xylographa difformis）。研究确认黄粉鳞盘衣（Lecidea xanthococcoides）为卡杜盘衣（Lecanora cadubriae）的同物异名。本文报道加利福尼亚州特有种金曼鳞盘衣（Lecidea kingmanii）可产生4-O-去甲基平酸（4-0-demethylplanaic acid，原文此处数字0应为字母O，已按正确化学术语译出）。研究将单孢多孔衣（Polysporina simplex）处理为无丝盘衣（Acarospora simplex），将瓮形多孔衣（P. urceolata）处理为无丝盘衣（A. urceolata）。同时为陀螺形多孔衣（Polysporina gyrocarpa）提出新组合：陀螺状无丝盘衣（Acarospora gyrocarpa）。
