Popis: Three new species are described as follows: Gypsoplaca alpina H. X. Shi and Li S. Wang, G. bullata H. X. Shi and Li S. Wang, and G. rosulata H. X. Shi, Li S. Wang, and Timdal sp. nov. Gypsoplaca alpina is characterized by a small thallus, upper cortex with very thick gelatinized layer, ascocarp warty with a cerebriform ridging, and by growing on soil in alpine meadows. Gypsoplaca bullata characterized by having bullate ascocarp, uneven to bullate thallus. Gypsoplaca rosulata is characterized by rosulate thallus and 4–6-spored asci. The new combination Gypsoplaca blastidiata (Zhurb) H. X. Shi and Li S. Wang comb. & stat. nov. is proposed. A phylogenetic tree is established, based on combined sequences of ITS and nrLSU, and all species formed monophyletic clades. Two main chemical compounds, brialmontin and sesterterpenes, are reported for the first time from Gypsoplaca by analysis of NMR and MS data. Triterpenoids are absent in Chinese Gypsoplaca specimens.
