Note: "Caloplaca albolutescens, C. atroflava, C. demissa, C. erythrocarpa, C. soralifera, C. teicholyta, C. xerica are clearly related to the genus Pyrenodesmia, but more sequence data are needed to resolve the relationship of this genus to the C. xerica group and C. demissa" (Arup et al. 2013: 74).
