A new multispored Lecanora species from China is proposed as L. moniliformis, which is similar to L. japonica but differs by its crenate apothecial margin and the presence of psoromic acid. A detailed taxonomic description, ecological and chemical characters, and illustrations are provided for the new taxon, and a key to the multispored species of Lecanora is presented. Keywords: 16-spored; east Asia; Lecanoraceae; lichenized fungi; taxonomy.
