Distinguished from the preceding by the paler thallus, the absence of 

 isidia, and the presence of greyish or sordidly caesious soredia. The 

 thallus is usually small, and is either strictly monophyllous or sublobate

 Abrotliallus Welwitzschii, sometimes found on the thallus, might be 

 mistaken for apothecia.
