Abstract
Three new species, Lecidea flavothallia, L. sublaboriosa, and L. tibetica, are reported from China based on morphological, chemical, and molecular characters. Lecidea flavothallia is characterized by an orange thallus and the presence of schizopeltic acid. Lecidea sublaboriosa is characterized by a sparsely developed thallus, brown hypothecium, and the presence of 4-O-demethylplanaic acid in the apothecia. Lecidea tibetica is characterized by a well-developed thallus, I+ violet medulla, hyaline to pale straw-colored hypothecium, and the presence of 2'-O-methyperlatolic acid as the major secondary metabolite. All of the new species were collected from the Qinghai-Tibetan Plateau in Southwest China. Detailed descriptions, discussions, and figures are provided for each species, along with a key for all known Chinese Lecidea s. str. species.
根据形态、化学和分子特征报道了3个新种：黄花Lecidea flavothallia、L. subblaboriosa和L. tibetica。黄花Lecidea flavthallia的特点是具有橙色的菌体和分裂酸的存在。下棘球蚴的特点是：囊体稀疏发育，下鞘呈棕色，囊液中含有4- o -去甲基planaic酸。藏蓝蛭的特点是：菌体发育良好，髓质呈紫色，下膜呈透明至浅草黄色，主要次生代谢物为2′- o -甲基草酸。本文提供了每个物种的详细描述、讨论和图表，并提供了中国所有已知物种的钥匙。
