Chaenothecopsis xishuiensis sp. nov. to Science and Lecanora pseudargentata Newly Reported from China

In order to provide data for lichenologists studying taxonomy, Chaenothecopsis xishuiensis is supported and proposed as a new species from China based on phenotypic, molecular, metabolite data. It characterised by leprose thallus, single, conical hemispherical apothecia, nonbranching stipe, cylindrical, eight-spored asci, nonseptate brown spores, this lichenised fungus contains atranorin zeorin in the thallus. addition, Lecanora pseudargentata reported first time record China. This red-brown dark apothecial discs, nonseptate, hyaline presence of gangaleoidin. The biological activity its lichen substances discussed.
