First read the description for Candelariella vitellina f. vitellina elsewhere on this web site. C. aurella differs in its thallus of scattered, mustard-yellow granules on a black prothallus. C. aurella is well adapted to urban settings and will grow well on garden walls in large towns and cities that are constructed from calcareous rock or brick. It has a K negative reaction.

Key characteristics

  • The black prothallus may be the dominant part of the thallus, especially in urban areas. Over this area, small yellow granules and discs are scattered. The similar Candelariella vitellina always has a better developed, granular yellow thallus
  • On urban walls mostly.
