One specimen (Sokoloff 252) was collected on a rock inside the passageway connecting the MDRS "hab" with the Musk Observatory. Though we follow Brodo et al. (2001) in treating this species as a member of Caloplaca , some authors treat this species as Xanthomendoza trachyphylla (Tuck.) Froeden , Arup & Sochting ( Arup et al. 2013 ). Caloplaca trachyphylla is common in western North America ( Brodo et al. 2001 ). Supplemental Files: CANL 127956 (Suppl. material 17), CANL 127957 (Suppl. material 18).
