Valadbeigi et al. (2011) . Notes. " Immersaria " Immersaria iranica has lecanorine apothecia, a distinct epinecral layer and halonate ascospores ( Valadbeigi et al. 2011 ). The materials from China are in accordance with the materials of Iran, based on comparisons with the original descriptions and the photographs given by Valadbeigi et al. (2011) . The characters of this species are consistent with the new genus and the phylogenetic results showed that it was clustered with species of Lecaimmeria . Therefore, it was transferred to Lecaimmeria . This species is currently known from Iran and China. Specimens examined (SDNU). China . Xinjiang : Urumqi , Mt. Tianshan-glacier No. 1, alt. 3800 m , on rock, 2011, Z.L.
