Caloplaca albolutescens (Nyl.) H.Olivier

Thallus crustose, greyish white, lacking an upper cortex and becoming powdery greyish-sorediate, margins without lobes; apothecia orange, with thin, whitish thalline margins, and with proper margins concolorous with the disks. An uncommon species of basic rocks and concrete, apparently widespread but distribution uncertain due to substantial past confusion with C. teicholyta. Many and perhaps the majority of northern records of the latter belong here.
