Parmelia-like, green-grey leafy lichen with a soralia-punctured outer layer (cortex) giving it a white-spotted appearance. P. jeckeri is distinctive in having the majority of its soralia running like a band along the raised edges of the lobes, these being otherwise of a dark brown (burnt) and sometimes frosted appearance. It is an epiphyte of waysides, parks and urban spaces. In Ireland, the species is frequent.

Key characteristics

  • Thallus foliose, green-grey above, pale brown below, spotted, numerous soralia dusting the edges of the lobes like a border
  • Wayside trees in villages, towns and cities: spreading.
