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。本研究共计报道该森林全境共414个地衣型真菌（lichenized fungi）类群；其中圣哈辛托山脉（含圣罗莎山脉）记录有327个类群，圣贝纳迪诺山脉则记录有289个类群。本文记述2个科学新种：Lecanora remota 与 Lecidea stratura。另报道2个尚未正式定名的Bellemerea属与Scytinium属类群，目前二者均处于研究阶段。另有5个物种为北美及加利福尼亚州的首次记录：Gloeoheppia rugosa、Lecanora formosa、Peccania cernohorskyi、P. corallina 以及 Psorotichia vermiculata。其中Peccania cernohorskyi同时为加拿大不列颠哥伦比亚省的首次记录物种。另有8个物种为加利福尼亚州的首次记录：Caloplaca diphasia、C. isidiigera、Peltigera extenuata、Rhizocarpon simillimum、Rinodina lobulata、R. terrestris、Sarcogyne squamosa 以及 Xylographa difformis。研究确认Lecidea xanthococcoides 为 Lecanora cadubriae 的同物异名。报道加利福尼亚特有种Lecidea kingmanii可产生4-O-去甲基普兰酸（4-0-demethylplanaic acid）。将Polysporina simplex 处理为Acarospora simplex，将P. urceolata 组合为A. urceolata；并为Polysporina gyrocarpa 提出新组合Acarospora gyrocarpa。
